The Forgotten Era: When Bed Bugs Were Tested for Combat in Vietnam

In 2004, Brooke Borel got bed bugs in New York. Then she experienced them again in 2009—twice in two different apartments. Because of those experiences, which were part of a widespread bed bug resurgence in the US, Borel, a science journalist, decided to explore why the bugs were back. This excerpt is one of many stories from her new book: Infested: How the Bed Bug Infiltrated Our Bedrooms and Took Over the World.


In 1965 at the Limited War Laboratory in Aberdeen, Maryland, army entomologists were testing bed bugs for combat. The Vietnam War had escalated on the other side of the world, and the Vietcong were putting up a more impressive fight than the Americans and their allies had expected. The enemy’s familiarity with the jungle made it easy to ambush US soldiers; the army was thus desperate to flush the guerillas out.

The Americans stripped the leafy jungle greens with Agent Orange and other defoliants so that the trees could no longer conceal an attack, and they trained German shepherds to sniff out hidden enemies sneaking through the ruined forest remains. But the researchers at Aberdeen thought that the bed bug might be a more versatile lookout. Compared to dogs, insects were easier to transport, required less care and attention, and needed no training.

Bed bugs are also naturally attracted to humans. The scientists wanted to exploit this tendency, whether in this species or a short list of other bloodsuckers, to see if they could detect the heat coming off of an enemy’s body or the carbon dioxide from his breath. In addition to the bed bug, the contenders included an unnamed species of lice; Xenopsylla cheopis, the Oriental rat flea; Amblyomma americanum, the lone star tick; three mosquito species; and Triatoma infestans, the kissing bug and most infamous carrier of Chagas disease.

The scientists put each species through a series of tests to observe how the insects acted when a person was nearby and to see whether that action could be converted into a warning signal. Lice were ruled out early because their aimless crawls didn’t change when a person was nearby. The fleas did notice the presence of a person, but they became so excited when they smelled a potential meal that they tapped like kernels of popcorn against a metal detection chamber and took too long to settle back down, which meant they were sensors that couldn’t reset. The soft feet of the tick made no discernible noise even after the researchers hung weights from the arthropods’ legs in hopes that the additional heft might audibly scrape across a detector’s surface.

In tests on one species of mosquito, the insects responded by probing a screened, skin-like membrane, thinking it was food whenever the researchers wafted in a human scent. A phonograph pickup, the same device that captures the vibration from the strum of an electric guitar and converts it to an electrical signal, connected to the membrane and converted the action of each wishful bite so it resonated like a plucked guitar string. And the kissing bug, a distant cousin of the bed bug, made a raucous noise with each of its footsteps, which was promising.

Both adult and nymph bed bugs sprung to attention when a meal was nearby, but only the younger bugs reacted strongly enough in initial tests to warrant the construction of a complex sensor. The researchers made one from a coiled spring of piano wire connected to a phono pickup. Just as the mosquitoes bit the fake skin in their detector, the bed bug nymphs shimmied across the piano wire, triggered it, and produced a sound. But when the wires, the bugs, and the pickup were put in a portable container—a small mesh envelope—the sound was too muffled to hear. The intrepid scientists built a chamber of fine steel wool and put the bugs and the detector inside. This helped, but the device still was not good enough to be useful on the battlefield. None of the other insect finalists that the army entomologists tested worked out, either, and the project was abandoned.

That the bed bug was included in the Aberdeen research in the sixties was unusual— as the bed bug faded from homes and our collective memory, it also became less common in the laboratory. In the decades leading up to World War II, scientists had mainly tried to understand the bugs’ basic biology, whether they were a health threat, and how to kill them. Both during and directly after the war, the research slanted toward pest control through experiments using DDT and other poisons.

By the late fifties, just after DDT’s initial deluge, the scientists’ interest dipped for about a decade, corresponding with the decimation of the bug. In the years that followed, what little research there was came from the developing world, where the pest was still a problem: countries in Africa and Asia, or institutions including the London School of Hygiene and Tropical Medicine, which often operated in those regions. Just a handful of studies were published each year. Many looked at the tropical bed bug rather than the common one, and most of the work focused on public health, pesticide effectiveness, or, as bed bugs evolved to withstand DDT and its cousins, pesticide resistance. The research on the latter grew in the decades following the war, for even DDT couldn’t completely destroy what nature had perfected over millennia, and thus bed bugs hadn’t disappeared entirely.

Four years after the Americans and the Brits added DDT to their wartime supply lists, scientists found bed bugs resistant to the insecticide in Pearl Harbor barracks. More resistant bed bugs soon showed up in Japan, Korea, Iran, Israel, French Guiana, and Columbus, Ohio. In 1958 James Busvine of the London School of Hygiene and Tropical Medicine showed DDT resistance in bed bugs as well as cross- resistance to several similar pesticides, including a tenfold increase in resistance to a common organic one called pyrethrin. In 1964 scientists tested bed bugs that had proven resistant five years prior but had not been exposed to any insecticides since. The bugs still defied the DDT.

Soon there was a long list of other insect and arachnid with an increasing immunity to DDT: lice, mosquitoes, house flies, fruit flies, cockroaches, ticks, and the tropical bed bug. In 1969 one entomology professor would write of the trend: “The events of the past 25 years have taught us that virtually any chemical control method we have devised for insects is eventually destined to become obsolete, and that insect control can never be static but must be in a dynamic state of constant evolution.” In other words, in the race between chemical and insect, the insects always pull ahead.

Chagas Disease in the United States: A Growing Public Health Concern

 Each month, The Clinical Advisor makes one new clinical feature available ahead of print. Don’t forget to take the poll. The results will be published in the next month’s issue.

Chagas disease is a parasitic infection caused by the protozoan parasite Trypanosoma cruzi (T cruzi).  T cruzi infection can be acquired through the vector-borne route, transplacentally, through transfusion of contaminated blood products, from a transplanted organ of an infected donor, or rarely from contaminated food or laboratory accidents.1 A majority of infections are transmitted via the vector-borne route, which occurs only in the Americas. The vector for T cruzi is the triatomine bug, also known as the “kissing bug.” Infection is acquired through contact with the feces of an infected triatomine bug. The triatomine bug has been found in the southern United States, Mexico, Central America, and South America — as far south as Argentina. Chagas disease is endemic in Latin American countries, including Mexico and most countries in Central and South America.2 Although the triatomine bug survives in the southern United States, the vast majority of persons infected with T cruzi living in the United States acquired the infection while living in Latin American countries.

The United States is considered a nonendemic country for Chagas disease.  As of 2009, more than 300,000 persons living in the United States were believed to be infected with the T cruzi parasite.3 Although a 2016 review places this number closer to 240,000, this estimate does not include undocumented immigrants, who could account for more than 100,000 cases.4 If left untreated, the parasitic infection can lead to chronic disease with severe and life-threatening manifestations.  In approximately 20% to 30% of T cruzi infections, the disease progresses to Chagas cardiomyopathy and/or gastrointestinal Chagas disease.1 Practitioners serving communities with large populations of Latin American immigrants need to be aware of the disease prevalence in this population.

Which of the following statements regarding Chagas infection is true?

 

Epidemiology

An estimated 8 million people worldwide are infected with T cruzi, and the United States has the seventh highest prevalence of Chagas infections. Of the estimated 300,000 US individuals infected with the parasite, 30,000 to 45,000 will develop Chagas heart disease.5 Chagas infections represents a growing public health concern in the Western hemisphere, particularly in communities with high populations of Latin American immigrants.  The majority of cases of T cruzi infections in the United States are among immigrants from Latin American countries where T cruzi infections are endemic; few actual vector-borne cases of infection have been reported in the United States. According to Bern and Montgomery, only 7 cases of US vector-borne infections have been reported since 1955 despite the presence of the triatomine bug in the southern states.3

The kissing bug can be found in the southern half of the continental United States and large parts of Central and South America.1 The climate in the northern portions of North America and the southernmost portions of South America are not compatible for triatomine bug survival. Vector-borne transmission is prevalent in endemic countries where housing is poorly constructed as the bugs like to nest in cracks and holes in substandard housing.  Improved housing and less-efficient vectors may explain the low risk of vectorial transmission in the United States.1,2 Plastered walls and sealed entryways help to prevent bug infestations.

Risk Factors

Persons at highest risk of contracting T cruzi infection are those living or who have lived in poorly constructed, triatomine bug-infested houses in endemic countries.1 Other persons at risk are those who have received blood transfusions, transplant recipients, and offspring of infected mothers.  Since 2012, donated blood at all US blood centers undergoes screening for T cruzi infection; therefore, US blood transfusion recipients since 2012 are not considered high risk.1 Transplant recipients who receive an organ from a donor infected with T cruzi and children born to infected mothers are at risk of developing Chagas disease.1

Public Transportation Seats Might Have Bed Bugs On Them

It’s no secret that public transportation is an ideal way to combat gridlock and reduce greenhouse gas emissions from cars. However, if you sit down on the bus or subway on the regular, the gross things on public transportation seats might make you vow to never put your butt on a seat again. This is especially true if you live in Los Angeles or Chicago where metro and el trains sport seats made of fabric, which are more difficult to keep clean.

If you’d rather live in denial, I totally support that, and you should stop reading right now because the Los Angeles Times reported that these seats are home to bed bugs, lice, urine, food, and dangerous bacteria. Despite being cleaned daily, and dry cleaned often, with more than a million trips a day, fabric seats are almost impossible to keep germ free.

In fact, one regular Los Angeles Metro rider told the Times that he hasn’t sat down on the train since a bed bug crawled from a seat onto his lap. “Sometimes you’re tired, or you don’t feel good, and you just want to sit down,” perfume designer and visual artist Chris Rusak said. “But you know what? It isn’t worth it.”

Giphy

He’s right. If standing on the train can reduce your chances of bringing home bed bugs, do it. After all, 20 minutes of standing is a small price to pay to avoid months of anxiety and expensive pest-control treatments because a bed bug hitched a ride on your belt loop.

Another metro rider told the Times that she got lice after her hair long hair touched a seat. The story also noted that one rider reported witnessing a Metro employee place a paper towel on a seat before sitting down. It’s kind of like when the employees of a restaurant won’t eat the food. Obviously they know something you don’t, and it’s probably best to follow their lead.

Throwback psychedelic-looking fabric-covered seats are designed to disguise dirt and stains, which is why they look like the carpet used in Las Vegas casinos. And while fabric seats are certainly the grossest, germs and pests can cling to plastic and vinyl seats too.

A study from Travelmath found that the New York City Subways system is home to more mold and dangerous bacteria, which can cause skin infections and pneumonia, than any other city in the U.S. This makes sense because New Yorkers take public transport more often than residents of other cities. And more people equals more germs.

In the study of several cities, New York was the most bacteria ridden, San Francisco came in second, Chicago third, and Washington, D.C. fourth. (If you’ve ever ridden the metro in D.C. then you know it’s the unicorn of public transportation and has strict rules about what you can bring on board, which might account for its low levels of bacteria.)

In another study, a global team of scientists launched an initiative to get a snapshot of the bacterial ecosystem aboard public transportation, The Sydney Morning Herald reported. While they concluded that most of the bacteria is harmless, that doesn’t mean it isn’t gross. The study found that 20 percent of bacteria present in the New York City Subway system came from genitals — the result of improper hand washing and farting. Seriously.

Giphy

Other bacteria came from the human gastrointestinal tract and human skin. Because subway trains tend to be jerky, it’s pretty difficult to stand the entire time without holding onto the handrail, which is why proper hand washing is so important. What’s more, you should also clean your phone after riding public transportation because it’s pretty likely that you touched something gross on the train and then started scrolling through social media thus transferring those germs to your digital bestie.

Other germ ridden forms of transport include buses, taxis, and airplanes. Specifically airplane tray tables, which probably aren’t wiped down after every flight. If you’re super grossed out, Travelmath said that common sense is the best defense against germs on public transportation.

“Avoid touching surfaces if you can help it, keep your hands away from your face and out of your pockets to avoid spreading germs, and wash your hands as soon as you arrive at your destination.” Additionally, it’s a good idea to carry alcohol wipes with you when flying so you can wipe down the tray table and the touch screen before choosing your in-flight movie. Because, the germs on public transportation are sick AF, and not in a good way.

Judge allows lawsuits claiming Monsanto weed killer Roundup causes cancer to go forward

SAN FRANCISCO — Hundreds of lawsuits alleging Roundup weed killer causes cancer cleared a big hurdle this week when a federal judge ruled that cancer victims and their families could present expert testimony linking the herbicide to non-Hodgkin’s lymphoma.

U.S. District Judge Vince Chhabria said evidence that the active ingredient in Roundup — glyphosate — can cause the disease seemed “rather weak.” Still, the opinions of three experts linking glyphosate and non-Hodgkin’s lymphoma were not “junk science” that should be excluded from a trial, the judge ruled on Tuesday.

The lawsuits say agrochemical giant Monsanto, which makes Roundup, long knew about the cancer risk but failed to warn people. The ruling allows the claims to move forward, though the judge warned it could be a “daunting challenge” to convince him to allow a jury to hear testimony that glyphosate was responsible for individual cancer diagnoses.

Many government regulators have rejected a link between cancer and glyphosate. Monsanto has vehemently denied such a connection, saying hundreds of studies have established that the chemical is safe.

The company is facing hundreds of lawsuits in state and federal courts that claim otherwise. Chhabria is presiding over more than 400 of them.

A separate trial is under way in San Francisco in a lawsuit by a school groundskeeper dying of non-Hodgkin’s lymphoma — the first case a jury has heard alleging Roundup caused cancer.

In response to Chhabria’s ruling, Monsanto Vice President Scott Partridge noted the judge excluded some of the plaintiffs’ experts and called the opinions of those he is allowing to testify “shaky.”

“Moving forward, we will continue to defend these lawsuits with robust evidence that proves there is absolutely no connection between glyphosate and cancer,” Partridge said in a statement. “We have sympathy for anyone suffering from cancer, but the science clearly shows that glyphosate was not the cause.”

Michael Baum, an attorney for the plaintiffs, said he was still reviewing the ruling but was pleased the judge rejected Monsanto’s effort to have the lawsuits thrown out.

“We look forward to taking the next step — getting our clients their day in court,” he said in a statement.

The judge wanted to determine whether the science behind the claim that glyphosate can cause non-Hodgkin’s lymphoma had been properly tested and met other requirements to be considered valid.

Chhabria spent a week in March hearing dueling testimony from epidemiologists. He peppered them with questions about potential strengths and weaknesses of research on the cancer risk of glyphosate.

Beate Ritz, an epidemiologist at the University of California, Los Angeles, testified for the plaintiffs that her review of scientific literature led her to conclude that glyphosate and glyphosate-based compounds such as Roundup can cause non-Hodgkin’s lymphoma.

Ritz said a 2017 National Institutes of Health study that found no association between glyphosate and non-Hodgkin’s lymphoma had major flaws.

Monsanto brought in its own expert, Lorelei Mucci, a cancer epidemiologist at the Harvard T.H. Chan School of Public Health, who praised the 2017 study.

“When you look at the body of epidemiological literature on this topic, there’s no evidence of a positive association between glyphosate and NHL risk,” she said of non-Hodgkin’s lymphoma.

In his ruling Tuesday, the judge said Ritz and Mucci could both testify before a jury.

Monsanto developed glyphosate in the 1970s, and the weed killer is now sold in more than 160 countries. Farmers in California, the most agriculturally productive state in the U.S., use it on more than 200 types of crops. Homeowners use it on their lawns and gardens.

The herbicide came under increasing scrutiny after the France-based International Agency for Research on Cancer, which is part of the World Health Organization, classified it as a “probable human carcinogen” in 2015.

A flurry of lawsuits against Monsanto followed, and California added glyphosate to its list of chemicals known to cause cancer. Monsanto has attacked the international research agency’s opinion as an outlier.

The Environmental Protection Agency says glyphosate is safe for people when used in accordance with label directions.

A federal judge in Sacramento has blocked California from requiring that Roundup carry a label stating that it is known to cause cancer, saying the warning is misleading because almost all regulators have concluded that there is no evidence glyphosate is carcinogenic.

Mom claims she found bed bugs in daughter’s hospital room

An Arizona family is speaking out after claiming to find bed bugs in their daughter’s hospital room. Erin Ortega, whose daughter is being treated at Banner Desert Hospital in Mesa, said she and her wife allegedly spotted a bed bug on hospital-provided bedding on Monday night.

She claims she alerted hospital staff, who allegedly moved the family to another room for staffing purposes, Fox 10 reported.

Simple Method To Burn Belly Fat. As Seen On Shark Tank

“Sure enough, there was another bed bug on the floor behind the recliner, as well as a dead one that was stuck to the chair,” Ortega told Fox 10.

In a statement to the news station on Tuesday, the hospital said it immediately responds to any concerns raised by patients.

“We are responsive to any concerns expressed by our patients,” the statement read. “We take immediate action to remedy isolated incidents as soon as we are notified.”

WORLD CUP ATTENDEES URGED TO GET MEASLES VACCINE

But Ortega, who said her daughter has been receiving exceptional care at the facility, said she’s concerned other patients are unaware of the situation.

“We see family coming and going out of there still carrying bags, still carrying their sweaters, things like that, and it doesn’t seem that there’s much of a concern for their well-being,” she told the news outlet.

Bed bugs are not known to spread diseases, but they can cause itching and loss of sleep. A bed bug bite could also trigger an allergic reaction and require medical attention, according to the CDC.

Ortega, who has other children at home, said she and her wife have not been able to stay with their daughter over concerns about the bed bugs and the risk of bringing them home. She also said they are considering transferring their daughter to another facility.

According to Experts: Most Public Buildings In Montreal Have A Bed Bug Problem

According to Experts: Most Public Buildings In Montreal Have A Bed Bug Problem featured image

For some reason, bed bug infestations in Montreal are a common occurence. There’s even a public map that depicts all reported instances of bed bugs in the city.

ALSO READ: Toronto Is Dealing With A Gun Violence Epidemic

This week we learned that the widespread problem even extends to popular public institutions. The bed bug problem at Montreal’s largest public library, the Bibliothèque et Archives nationales du Québec (BAnQ), has become so severe that library officials had to remove all cushioned furniture from the building. Some are even considering removing all upholstered pieces from the library.

Today, the Montreal Gazette first reported that, in fact, most public buildings in the city have had a beg bug problem.

Yes, tiny blood-sucking insects roam the halls of public Montreal institutions.

City officials have remained tight-lipped about just where and how often the city has to combat the creepy crawling creatures. Though, the Gazette also reports some city employees have received special training to prevent and deal with infestations. If the city is willing to invest that much time and money into such trainings, the problem must be huge.

Cases reported in libraries, hospitals, and universities received much public attention.

Montrealers who spot bed bugs in their homes or public buildings can file a report with the city. The Point-St-Charles Community Clinic warns that the most important thing Montreal residents can do is not try to deal with the situation themselves and instead call an exterminator.

In the meantime, avoid contact with anything plush the next time you visit a public building.

DMV To Temporarily Close After Alleged Bedbug Infestation

 

Brian Dorman, News on 6

In response to claims of a bedbug infestation, the DMV inside Eastgate Metroplex is now closed for 3 days.

The property manager says the DMV will be treated Thursday morning for bedbugs. But those affected by this problem there say that’s not enough.

“This whole place needs to be shut down. It’s not an isolated incident,” said Cynthia Odom. “We utilize these places on a regular basis and then for management to hide it. Even when I tried to contact them no one called me. It was just like, oh well, that’s your problem.”

Those pictures, as well as pictures from another woman claiming she was bitten, is putting the heat on the Eastgate Metroplex even shutting down DPS. Eastgate Property Manager Dave Ortenburger says the situation’s isolated.

“This talk of infestation is sensationalizing the whole situation there is not an infestation. Nobody and I mean, nobody is immune to bedbugs,” said Ortenburger.

Since the story aired on News On 6 others who are employed at other Eastgate businesses have come forward saying in the past they’ve been told to stay quiet. Ortenburger denied that anyone was told not to report the issue.

Cynthia Odom says she has contacted a lawyer and is hoping others will join her as she considers legal action.

Alorica’s Corporate office also released a statement earlier today.

At this time, we do not have any reported incidents of a bed bug infestation. The bed bug incident in question was located in a common area for the public at one of the other businesses in the complex, a complex with 40 businesses and 10,000 employees. With more than 1,000 employees serving our business not only do we perform monthly treatments to mitigate incidents, we also have standard protocols in place in the case of an infestation. Bed bug treatments including K-9 inspection, steam cleaning and chemical treatments with follow-ups to confirm eradication to the area in question. In addition, the company gives two paid days off to employees that report a bed bug concern immediately or even one day after they first discover an issue. During their two days off, the company pays for a free home inspection by a pest control company, as well as paying for any pest extermination costs.

Alorica deeply cares about maintaining healthy and safe working conditions for our team members and we will continue to work closely with employees to ensure any future events are handled appropriately and promptly.

While we do not provide specific details or comments regarding our former or current employees, I would suggest fact checking data regarding end of employment—reason, timing, etc.

Bed Bugs Found in Fox News Channel Newsroom

By Chris Ariens

TVNewser has learned that a small area of the Fox News Channel newsroom has evidence of insects believed to be bed bugs. What is not known is how the insects got into the basement-level newsroom of the News Corp. headquarters. Most likely, an employee or guest unknowingly transported the poppy seed-sized bugs on their clothing, which then made their way into the fabric or carpeting.

We’re told an exterminator was brought in late last week to treat the area and those who sit near there have been alerted to take precautionary measures including sending their clothes to the dry cleaner.

For the past several years New York City has seen a rise of bed bug outbreaks in city hotels and apartments.

Bedbugs infest Montreal’s biggest library

Grande Bibliotheque

Much of the Grande Bibliotheque remains open but some portions have been forced to close due to a bedbug infestation.

Anyone checking out a book from Montreal’s Grande Bibliotheque should be careful that they’re not also bringing home bedbugs.

Several sections of the city’s biggest library have been closed off as officials try to get a handle on the infestation. Upholstered chairs have been swapped out for plastic seats, and exterminators have been dispatched.

This is not the library’s first bedbug problem. In the past 13 years, there have been multiple episodes of bedbugs. In most cases, it’s been an isolated issue that’s been quick and easy to treat.

This time the tiny, brownish critters – which grow to be about the size of an apple seed — appear to have spread throughout the facility.

An estimated 7,000 people visit the Grande Bibliotheque every day. It’s unclear what may have prompted the problem, but library officials say it’s difficult to control what visitors may bring into the facility.

Other cities have experienced similar infestations. In 2016, 14 library branches in southwestern Ontario were temporarily closed after bedbugs were discovered at a library near Windsor. In that case, patrons were asked not to return borrowed items until the problem was under control.

One-third of Vancouver’s library branches were briefly closed in 2011 after bedbugs were found inside books in New Westminster Public Library’s fiction section.

Bedbugs have been known to spread in other public spaces, including buses, movie theatres and hospitals. As juveniles, bedbugs are translucent but eventually turn a brownish-red after they feed. Females can lay up to five eggs per day.

Mosquito trial takes a bite out of dengue and zika-spreading populations

Updated

A CSIRO experiment has managed to wipe out more than 80 per cent of a dengue fever-spreading mosquito near a far north Queensland town.

The CSIRO released more than three million sterile male Aedes aegypti mosquitoes in small towns near Innisfail last summer, and the females they mated with laid sterile eggs.

The researchers drove around the towns in van that used GPS sensors to release mosquitoes at certain intervals to get even coverage of the male mosquitoes across the area.

CSIRO research director Paul De Barro said the team partnered with James Cook University and tech company Verily for the “Debug Innisfail” project.

“We created a population of mosquitoes that had within them a naturally occurring bacterium called wolbachia,” he said.

“What we were doing is releasing only males that had this wolbachia, and they would cross with mosquitoes in the field, the wild mosquitoes that didn’t have that same strain of wolbachia, and as a result the wild females would only lay sterile eggs and so the population would crash.”

The Aedes aegypti mosquito also spreads diseases such as yellow fever, zika virus and chikungunya, making hundreds of millions of people sick in more than 120 countries each year.

Dr De Barro said the results of the experiment were promising for efforts to eradicate disease-carrying mosquitoes from urban areas.

“I certainly think with technology like this, and as it evolves over time, we will be in a situation where we could view a future Australia that didn’t have this mosquito,” he said.

“What we’ve demonstrated is the technology does work to at least suppressing.

“What Verily wants to do now is it wants to trial the technology in a location which has a large dengue problem.”

Dr De Barro said the trial sites near Innisfail were perfect for the experiment.

“You have a number of small towns surrounded by sugar cane, so they become little isolated, experimental patches,” he said.

“We were therefore able to have three towns that were treated and three towns that were not treated so we could get a very good picture of how the mosquitoes responded to the release of these sterile male mosquitoes.

The CSIRO said the project would end for now in far north Queensland and Verily was planning trials overseas.

A separate Monash University trial, the World Mosquito Program (formerly Eliminate Dengue), released wolbachia-infected mosquitoes in north Queensland aimed at replacing the local Aedes aegypti population with ones that cannot transmit dengue fever.

Queensland Health credited the project with reducing locally transmitted dengue cases in Cairns.
