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.
Eriophyid mites are a challenging pest for turfgrass managers due to their small size and poorly understood biology. A new guide in the open-access Journal of Integrated Pest Management outlines what is known about eriophyid mites, available management options, and avenues for future research.
Meet Marian Rodriguez-Soto, master’s student in entomology at Purdue University researching turfgrass pest management, Puerto Rico native, and subject of a new “Student Spotlight” feature on Entomology Today.
A simple change in the choice of grass varieties for lawns of St. Augustinegrass could be a key tool for fending off fall armyworm infestations, according to new research. While no single St. Augustinegrass cultivar rises above the rest in resisting infestation, mixing varieties may confer some benefits, as fall armyworms clearly preferred single-cultivar plantings in a series of lab tests.
