Planting strips of wildflowers next to crops is a boon for native bees, but few farms adopt the practice. A new study, however, shows farmers can turn an immediate profit by selling wildflower seeds retail, while the long-term benefits of increased pollination and crop yields materialize over time.
A study along a river in Central Mexico finds Hetaerina americana damselflies in reduced numbers after a decline in vegetation the addition of wastewater outlets. Researchers say the decline illustrates the impact of human land use on natural ecosystems.
In a new special collection on trap and cover crops in integrated pest management, experts review the latest research on various habitat-management methods and their applications in both deterring pest populations and fostering natural enemies of crop pests.
A new study finds several edible plant oils—such as hempseed, sesame, and pumpkinseed oils—have potential utility as eco-friendly larvicides or egg-laying deterrents against the Aedes aegypti mosquito.
Use of an insecticide can be counterproductive if it also harms natural enemies of a target pest. A new study puts several insecticides currently in use to manage spotted-wing drosophila to the test to see how they do or don't affect parasitoids of the invasive fruit fly.
Honey bees are incapable of buzz pollination, but they can (and do) perform pollination duties in highbush blueberry. A new study shows that, while honey bees rarely collect blueberry pollen in the pollen baskets on their hind legs, they frequently contact it with other body parts and transfer it to other flowers.
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.
A new study finds spotted-wing drosophila prefer red, glue-covered monitoring traps made of plastic rectangles or spheres compared to the most commonly used clear deli-cup traps. The findings will advance the pursuit of more efficient and effective monitoring techniques for the pest.
The Aedes aegypti mosquito typically prefers humid climates, but it has gained a foothold in the arid southwestern U.S. by using manmade containers for breeding sites—in particular, flower pots and the saucers underneath them.
Indigenous cultures in Colombia have known for a long time that stings from the little fire ant, Wasmannia auropunctata, can cause corneal lesions. Medical doctors are just figuring it out.
By John P. Roche As average temperatures rise globally, the ranges of many species will be affected. Climate-induced shifts in the ranges of invasive species will be particularly important because […]
By John P. Roche Spotted wing drosophila (Drosophila suzukii), is an invasive fruit fly species from eastern Asia, first seen in the United States in 2008. The species is devastating […]
By John P. Roche Blister beetles produce cantharidin, a 10-carbon isoprenoid molecule that is highly bitter and is toxic to most animals. Because cantharidin is so bitter, it discourages predators, […]
By John P. Roche West Indian sweetpotato weevils (Euscepes postfasciatus) are costly pests of sweetpotato plants (Ipomoea batatas) in the Pacific, the Caribbean, and Central and South America. Entomologists in […]
By John P. Roche Male Japanese stag beetles (Prosopocoilus inclinatus) have battles to defend territories to earn the opportunity to mate with females. They use enlarged mandibles that look like […]
Beetles may play a more important role in pollinating orchids than originally thought, based on a new beetle trapped in amber 20 million years ago
