High Temperature, Grasshopper Diet Boost Venom Production in Lab-Reared Scorpions
Researchers in Pakistan evaluated the factors that influence venom production in scorpions, with the aim to maximize venom extraction for research and medical uses.
In the Southern U.S., Young Blacklegged Ticks’ Habitat is a Mystery
In the southern U.S., blacklegged tick larvae and nymphs can be found on hosts, but they don't otherwise show up in vegetation or—as a new study finds—in leaf litter or soil either. So where are they hiding?
Train-the-Trainer Program Multiplies Reach of IPM Knowledge
In Missouri, a series of "train-the-trainer" workshops have provided extension educators with the latest knowledge in integrated pest management to share with growers throughout the state.
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.
Array of Management Methods Needed to Curb the Pesky Squash Vine Borer
The larva of the squash vine borer burrows into the stems and crowns of squash, zucchini, and pumpkin plants, causing wilting damage. A new guide in the open-access Journal of Integrated Pest Management outlines a variety of management methods to combat the squash vine borer.
Could Insecticide Netting Help Manage Brown Marmorated Stink Bug Infestations in Homes?
New research on brown marmorated stink bug behavior indicates they prefer darker surfaces, doorways, and the north and east sides of homes—and that insecticide-treated netting offers potential as a means of nuisance control.
Busy Bees: An Up-Close Look at One Bee Species’ Scramble to Mate
With high-speed, high-definition cameras, researchers at the University of Arizona got an unprecedented look at the mating habits of the solitary bee species Diadasia rinconis and gained new insights into their courtship behaviors and the selective pressures those behaviors produce.
Why Smoking Soothes the Stressed-Out Bee Hive
A new study that explores the effect of smoke on honey bee (Apis mellifera) behavior finds that it reduces the instance of bees releasing a venom droplet in their signaling of danger to other bees, which researchers speculate may thereby reduce the amount of alarm pheromone released.
Butterfly Pupae Make Sounds In Never-Before-Known Ways
New research explores how pupae of certain butterfly species make a "twittering" noise—via a wiggling movement that triggers sound from tiny structures in the membranes between their abdominal segments.
Tick-Repellent Clothing: How Laundry Suds Affect Your Permethrin-Treated Duds
A study on the durability of permethrin-treated clothing found that, after 16 cycles of wearing and washing the clothes, their repellent effect on ticks was indeed reduced, but it was still better than untreated clothing.
Cattle Call: Tick Surveillance Project Offers Model for Monitoring Livestock
A study in Tennessee found ticks on about one in six cattle and at livestock monitoring locations in all regions of the state, highlighting a "hidden health threat" to the cattle industry.
Study Explores How Flower-Eating Katydids Pick Their Meals
Research in Singapore on katydid florivory could have applications in agriculture or even weed control.
Meddling in the Mutualism: Fly Larva Uses Nectar to Lure Ants for Lunch
In the Brazilian savanna, the larvae of a fruit-fly species exploits an ant-plant mutualism by trapping and preying on ants atop the plant's nectar deposits.
Fluid Termite Bait Aims to Combine Best of Both Management Methods
A new termite-control method currently in development looks to combine the advantages of a liquid insecticide application with the comprehensive impact of existing solid termite bait systems.
Swim Lessons: How Two Land-Dwelling Ant Species Paddle Through Water
A new study in the Annals of the Entomological Society of America examines how two ant species swim and concludes that bigger is indeed better when it comes to which of them swims fastest.
