Need to Mail Mosquitoes? Pack Them Up Nice and Snug

Several emerging mosquito-management methods require the transport of mosquitoes to precise locations. There, lab-reared mosquitoes—for instance, sterilized males—mix with wild mosquitoes and hinder the population's ability to reproduce or transmit disease. But, getting mosquitoes from lab to wild presents logistical challenges. A team led by researchers at New Mexico State University are tackling this problem and have made a surprising discovery about just how tightly live mosquitoes can be packed up.

Tabloid Sensationalism Aside, Lady Bugs Are Still Fascinating

Despite headlines to the contrary in British tabloids this fall, harlequin ladybird beetles are not killing off native species by giving them a sexually transmitted fungal infection. "There have been stories mixing up various research findings into quite sensational headlines, which is a shame because these fungi and the ladybirds are fascinating in their own right," says ecological entomologist Helen Roy, Ph.D., of the Centre for Ecology & Hydrology in Wallingford, England.

So, You Want to Study Termite Control? Step 1: Raise a Few Million Termites

Subterranean termite colonies can be as large as 1 million individuals with a foraging territory and underground galleries stretching up to 100 meters long. How does an entomologist study something that large? Here's a behind-the-scenes look at how researchers at the University of Florida have raised entire termite colonies from scratch and devised experimental setups that mimic large foraging and nesting areas while still fitting inside a lab.

Organic Dust Takes a Bite Out of Ticks

Researchers at the USDA-Agricultural Research Service find promising results using clay and silicate dusts to combat lone star ticks. They hope the dusts could be a useful tool against tick species that transmit deadly pathogens to livestock.

For Good of the Colony, Sick Honey Bee Brood Sounds the Alarm

Honey bees detect and remove brood afflicted with parasites or pathogens. A new study shows that part of this "hygienic behavior" relies on chemical signals emitted by unhealthy brood, and brood coming from colonies bred to be more hygienic are more effective in signaling for their own removal.

Why Integrated Pest Management is Due for a Reset

In a new paper in American Entomologist, three experts suggest a modified focus for integrated pest management that better accounts for evolution and tolerance to pest injury and shifts from control toward management.
