Western Colorado Insects
Welcome to the Colorado State University Extension Western Colorado Entomology web site. This site was created and is maintained by Tri River Area Extension Entomology & Agronomy, and is dedicated to presenting factual information on the insects and insect related issues affecting western Colorado.
Spotted Wing Drosophila (Drosophila suzukii), was confirmed from Mesa County raspberries in early October 2014. This exotic pest of small fruits, stone fruits, and other soft fleshed fruits has been present on the front range near Ft. Collins since 2012.This is the first confirmed capture in western Colorado. SWD was first found in the US in 2008 and has since spread to many states and northward into Canada. For more information visit our spotted wing drosophila page.
