Much like the different environments of a forest floor and treetops, interactions among insects and related arthropods vary within the much smaller-scale vertical zones of a turfgrass “canopy.” Researchers using clay models of caterpillars to lure predatory arthropods are revealing what a difference a few centimeters can make.
Researchers at the University of Georgia are studying how clay models of caterpillars and other insect larvae can attract predator insects and arthropods in turfgrass and reveal their presence by the marks they leave behind. Their latest study fine-tunes the method by evaluating the colors, shapes, and sizes of the decoys that work best.
In a study on organic farms, researchers in Illinois find that field borders with a mix of grasses and flowering plants provide important winter habitat for arthropods that like to eat or parasitize crop pests, allowing these natural enemies to get an early start on emerging pests in the spring.
By Andrew Porterfield A new study from the University of Minnesota has found that the selective insecticide sulfoxaflor is just as effective at controlling soybean aphids (Aphis glycines) as broad-spectrum […]
