Khapra Beetle Can’t Beat the Heat
The khapra beetle does outsize damage to stored grains and is a top target at ports and border crossings. Researchers in Canada have found the threshold temperature that will kill the beetle at all life stages, even diapause.
Beer Brewers’ Spent Yeast Could Be Next Bait for Fruit Fly Pest
Researchers in China say a protein bait derived from leftover brewer's yeast attracted more spotted-wing drosophila flies than existing attractants in a lab test.
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.
Study Explores How Flower-Eating Katydids Pick Their Meals
Research in Singapore on katydid florivory could have applications in agriculture or even weed control.
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.
After 17 Years and 1,800 Tests, Researchers Find Cat Flea Pesticide Remains Effective
A 17-year study that monitored for resistance among cat fleas to the insecticide imidacloprid finds no evidence of decreased susceptibility. The study involved researchers in 10 countries, who tested more than 1,800 cat flea egg samples.
Tastes Like Chicken: Hydrogel Shows Promise as Yellowjacket Bait
Existing baits for yellowjackets require fresh meat as an attractant, but a new study finds that hydrogel makes an adequate substitute, absorbing insecticide and giving a tactile resemblance to meat to effectively bait yellowjackets in the same manner.
Bodycams Can Make for Better Agricultural Pest Management, Too
In a new study at the University of Arizona, researchers used body-mounted cameras to evaluate the efficiency of two insect pest sampling techniques—a sweepnet and a vacuum—in a cotton field. The perspective offered new insights into how such methods can be evaluated and could help growers and integrated pest management professionals further fine-tune their sampling techniques.
Got Aphids? Call in the Reinforcements With Banker Plants
To manage pest infestations in greenhouses, banker plants draw in different insect species that don’t feed on the main crop but do serve as hosts for predator insects that will also attack the pest on the main crop—a useful (and green) tool for integrated pest management.
The Collapsible Passive Trap: Mosquito Monitoring in a Lightweight Package
Evaluation of the collapsible passive trap for mosquitoes shows performs as well as other commonly used traps but in a lighter, easier-to-carry design, making it an attractive option for mosquito monitoring in remote areas.
New Ingredient Improves Pheromone Lure for Brown Marmorated Stink Bug
Researchers at USDA's Agricultural Research Service identified a chemical that enhances capture of the invasive brown marmorated stink bug (Halyomorpha halys) in pheromone traps
Citizen Scientists Collect 29,000 Mosquitoes in Germany and Help Detect Spreading Populations of Invasive Species
By Edward Ricciuti Armchair scientists nimble enough to catch insect lightning in a jar have helped the professionals map distribution of invasive mosquitoes in Germany—and they even detected three previously […]
Could Repellents Be Useful in Protecting Crops From Spotted-Wing Drosophila?
By Edward Ricciuti Cornell University scientists are tuning up the entomological version of psych war tactics that, instead of killing insect pests outright, manipulate their behavior so they avoid crops […]
How Flashy Wings, UV Light, and Seasons All Play a Role in One Butterfly Species’ Mating Rituals
By Edward Ricciuti Males of an African butterfly, with the improbable nickname of “squinting bush brown,” are the Lepidopteran version of chick magnets—if their generation of caterpillars chills out while […]
UV Light Best for Luring Cigarette and Drugstore Beetles
By Edward Ricciuti Their common names—cigarette beetle and drugstore beetle—only hint at the amazingly eclectic and destructive diet of two related insects, which can wreak havoc on products stored in […]
Researchers Develop Improved Lab-Testing System for Mosquito Repellents
By Edward Ricciuti Among the processes by which researchers gauge the effectiveness of a mosquito repellent is one that depends on convincing a volunteer to shove an arm treated with […]
