A group of researchers gets creative with some simple materials: strips of cardboard, rolled up and tied with string. Affixed to tree trunks or limbs, the "trunk refugia" show promise as a simple and inexpensive tool for sampling tree-dwelling insects and arthropods.
It's easier to manage an insect pest if you can predict where and when it's likely to show up, rather than trying to react after it appears. The USA National Phenology Network's "Pheno Forecast" maps offer daily updates that model the temperature conditions necessary for a dozen forest insect pests. A new article in the Annals of the Entomological Society of America showcases the tool, part of a new special collection on geospatial analysis of invasive insects.
A trailblazer for women in forestry, the U.S. Forest Service's Iral Ragenovich has worked on managing more than a dozen different forest pests in her 46-year career. Get to know Ragenovich in the next installment in Entomology Today's "Behind the Science" series.
In a recent study in Germany, targeted delivery of insecticides by unmanned aerial vehicles was effective against oak processionary moths. Researchers say such drones are suitable for aerial spraying during field studies and may open new doors for "precision forestry."
