Six-Legged Giant Finds Secret Hideaway, Hides For 80 Years

A 12-centimeter-long stick insect that hadn’t been seen for 80 years was rediscovered in 2001. Only 24 individuals remained, so conservation became vitally important.

Today, there are over 9,000 of the stick insects, thanks to the conservation efforts at the Melbourne Zoo. However, they are still considered critically endangered by the IUCN.

Bed Bugs Unfazed By Ultrasonic Devices, Researchers Report

Bed Bugs Unfazed By Ultrasonic Devices, Researchers Report

Northern Arizona researchers Kasey Yturralde and Richard W. Hofstetter tested four different products, none of which successfully drove away bed bugs.

With bed bugs bunking just about everywhere these days, people battling the bloodsucking insects may be tempted to try their hand at driving them away. But ultrasonic bug zappers, which retail for less than $25, aren’t the solution, say entomologists who tested some of the devices.

Northern Arizona researchers Kasey Yturralde and Richard W. Hofstetter tried out four different ultrasonic devices available on Amazon: one designed specifically for bedbugs and three that claimed to repel insects and small furry mammalian pests.

Their simple experimental design consisted of two 5-gallon buckets lined with sound-muffling insulation that were connected by a tube. An ultrasonic device was placed in one bucket, and eight to 10 bed bugs were placed in the tube.

More care was given to how the bedbugs were housed in the lab. The researchers kept them in large jars, like those used for canning, which were placed in bins full of soapy water. And every lip or edge over which a rogue bed bug would have to crawl was covered in a slippery substance a little like liquid Teflon, Yturralde says, to keep them from escaping.

In test after test, the bed bugs showed no preference for either bucket. None of the four devices drove the bed bugs away.

INTEGRATED PEST MANAGEMENT PROGRAM KEY TO SUCCESSFUL PEST CONTROL

INTEGRATED PEST MANAGEMENT PROGRAM KEY TO SUCCESSFUL PEST CONTROL

Hulett Environmental discusses the importance of creating an integrated pest management (IPM) program

IPM is a process involving common sense methods and environmentally friendly solutions for controlling pests. The approach incorporates three basic steps: inspection, identification and treatment by a pest professional.

The goal of IPM is to stop pests before they invade homes. Developing an IPM program with a professional will give homeowners peace of mind that they will be protected against pest-related health and property threats.”

There are a few standard pest prevention protocols in every IPM program. Pest experts at the National Pest Management Association (NPMA) and Hulett recommend the following techniques:

  • Seal cracks and holes on the outside of the home including entry points for utilities and pipes.
  • Screen vents and openings to chimneys, and keep tree shrubbery well trimmed and away from the house.
  • Eliminate sources of moisture and keep basements, attics, and crawl spaces well ventilated.
  • Store garbage in sealed containers and dispose of it regularly.
  • Keep counters, floors and other surfaces clean and free of crumbs.
  • Store food in plastic or glass containers with secure lids.
  • Vacuum often.

Top Five Pest Stories of 2012

Top Five Pest Stories of 2012

From the West Nile virus and Yosemite Hantavirus outbreaks to Lyme disease and the plague, it could be argued that 2012 was the year of pest-related infectious diseases. But, there were also some weird and wacky pest stories that grabbed headlines over the past twelve months. Here’s the list of the top five pest stories of 2012, as ranked by the National Pest Management Association (NPMA):

West Nile Virus (WNV) Outbreak: The mosquito-borne WNV outbreak became the second-worst in the history of the country. According to the Centers for Disease Control and Prevention (CDC), there were 5,387 cases of WNV disease in people, including 243 deaths in 2012.

Hantavirus and the Plague: Ten people fell ill and three died from exposure to deer mice infected with Hantavirus after staying in tent cabins at Yosemite National Park. A Colorado girl was also infected with the Bubonic Plague, a rare disease that wiped out one-third of Europe in the 14th century.

Acorn Crop Boosts Ticks: This spring, the tick season was heavier than in previous years due to an increase in 2010’s acorn crop and a decrease in the white-footed mouse population this year. These strange events forced many ticks to find new warm-blooded hosts – humans, which caused a surge in Lyme disease.

Spider Calls Woman’s Ear Home: One of the strangest and most unusual stories of 2012 has to do with a spider that was recently removed from a woman’s ear canal after doctors found it living inside for five days.

Termite Species Re-Identified: An aggressive termite species was recently re-identified in Broward County, Fla. Native to the Caribbean, tree termites — once thought to have been eradicated in the United States — can cause widespread property damage in a short period of time. This species is being carefully watched by experts because it’s difficult to control with existing treatment methods.

Will we ever… get rid of bed bugs?

Will we ever… get rid of bed bugs?

Many countries have seen a surge in infestations of the bloodsucking pest over the past decade. Brooke Borel examines what’s needed to tackle the re-emerging threat.

 

 

Why do we need to sleep?

 

 

Nothing makes the skin crawl more than the idea that tiny bloodsucking bugs could be living in our bedrooms. Around the size of a lentil, the common bed bug*, Cimex lectularius, can drink up to seven times its own weight in blood in one feeding, leave nasty, itchy bumps on their human hosts, and hide unseen for months on end.

Since the late 1990s, the bed bug has become an increasingly common urban nuisance in homes and hotels worldwide. A 2010 survey from the University of Kentucky and the National Pest Management Association found that 95% of US pest control companies had treated a bed bug infestation in the previous year, up from 25% a decade before, and 11% before that. Only last month, New York’s Department of Health and Mental Hygiene, a resource for other people with bed bug infestations, had to fumigate one of its floors.

According to the survey, the majority of pest control operators from Europe, Africa, Australia and North America said bed bugs were the most difficult insect pest to control, more so than ants, termites and even the formidable cockroach. Another study showed that in London alone, bed bug treatments grew by a quarter each year between 2000 and 2006.

The worst aspect about this is that we thought we had tackled the bed bug problem before. Clive Boase, a pest management consultant in Suffolk and author of the London survey, says that UK bedbug numbers began decreasing in the 1930s, thanks to changes in social housing and public health policies, which led to the demolition of old publicly-funded housing and teams of inspectors checking homes for vermin, respectively. New pesticides introduced in the 1940s, including DDT, also helped to bring numbers down, and by the 1950s infestations were rare. The US saw a similar drop in infestations from the late 1940s onwards, thanks to the advent and widespread use of DDT and other chlorinated hydrocarbon pesticides.

So, where is the chemical cure this time around? Or, is there any relief to be found in the myriad bed bug products and services on the market, from growth regulators to heat treatments?

Fighting resistance

The pesticides currently available, says Dini Miller, an entomologist and bed bug expert from Virginia Tech, are “not practical to use in a widespread way because of the cost.” New, cheaper pesticides are too expensive and time consuming to develop, she adds. Because bed bugs live primarily in the bedroom, chemical companies must provide extensive toxicity data to prove it is safe for indoor use, as it might come into contact with people or pets.

But, proving that a pesticide works and is safe could cost a company up to $256 million over eight to ten years for each active ingredient, according to a 2010 industry study conducted for Crop Life America and the European Crop Protection Association. The investment may not be worth it. The US accounts for over a fifth of the world’s pesticide use, the vast majority of which is used in agriculture, followed by herbicides and then insecticides. Compared to the vast expanse of farmland and orchards, the real estate of all of the apartments and houses in the world combined is small and brings in less money, says Miller. This is especially a problem considering patent protection on a novel ingredient runs out after around 20 years, after which the tech is open to generic competitors.

Even if making a new bed bug insecticide were lucrative, there are other challenges. There is the problem of figuring out how a chemical has to function in order to best kill bed bugs cheaply, efficiently and safely. This requires intimate knowledge of the bed bug’s basic biology. But, because bed bugs were at such low levels for decades, interest in studying them waned. Starting in the early 2000s, once it was clear the resurgence was real and that bed bugs weren’t going anywhere, scientists had to relearn bed bug basics from scratch, starting with fundamental aspects as how to raise them in a lab.

Then there is the problem of paying for the research. While dozens of labs now work on the basic science of bed bugs worldwide, funding remains low in part because bed bugs are not known to spread disease.

Finally, there is the problem of insecticide resistance. Even DDT, the supposed miracle cure, wasn’t immune to this. Five years after the pesticide was in widespread use in the US, DDT-resistant bed bugs popped up in Hawaii; in the 1950s and 1960s, resistant strains were found elsewhere in the US and in Japan, Korea, Iran, Israel and French Guiana, to name a few.

No chemical insecticide is immune to resistance, particularly if it is overused. Today, roughly 90% of bed bugs have a genetic mutation that makes them resistant to pyrethroids, a class of insecticides commonly used for bed bugs that work in a similar way to DDT.

Stopping spread

So, chemicals are not the sole answer. Neither, it seems, are any other options when used alone. “There is no silver bullet,” says Michael Potter, an entomologist from the University of Kentucky. Still, chemicals and other tactics can be used in an integrated pest management strategy, where they are sometimes used sparingly along with heat treatments (bed bugs die at 45C), desiccants such as silica gel and diatomaceous earth that fatally dry the bugs out, or vacuuming and getting rid of clutter.

Biological tactics are emerging as another possible option. Insect growth regulators, or IGRs, are chemicals that prevent bed bugs from completing their lifecycle, stunting their growth so they can’t reproduce. But, IGRs are slow-acting, and the bugs will still bite even if they can’t breed. On the horizon, perhaps, are genetically modified versions of symbiotic bacteria that live in the insect’s gut, including Wolbachia, which may be exploited for pest management. Or, the bugs’ pheromones, which tell them where to go and who to mate with, may also be reengineered and used against them.

In the meantime, public awareness measures can keep bed bugs from spreading. Good practices include: checking hotel room beds before unpacking, being mindful of belongings like a coat draped carelessly on an unknown couch, washing clothing in hot water and vacuuming suitcases after travelling, and avoiding discarded furniture on the street. Some experts also recommend sealing mattresses and box springs in encasements specifically intended to keep away bed bugs, which may make the bed easier to treat and could save it from permanent damage.

These combined efforts have knocked down infestations in some areas, says Boase, particularly among high-end hotels and the rich. Both can afford to throw money at the problem. Right now, he adds, the most severe infestations in the UK are in low-income housing – not because poor people are more apt to get them, but because they are less likely to be able to afford the treatments. The US has a similar problem. Better control will depend on cheaper, more efficient options entering the market.

“I feel that it is possible to bring infestation levels down in that residual housing area, but we don’t have the tools of infrastructure to support it,” says Boase. Then again, he says, “we’ve never had [total] eradication before.” But, with cheaper tools, we may be able to knock bed bug levels back down everywhere. Or at least, he adds, “we love to think we can.”

* Many people write “bedbugs”, but entomologists use two words when describing Cimex lectularius, because it is a “true bug” (Hemiptera). Entomologists always use two words for insects that are true to the common name they have – so for example, house fly is two words because those are actually flies, but butterfly is one word because they aren’t flies.
