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.

Brown Marmorated Stink Bug
|Brown marmorated stink bug is present in Colorado in low numbers. Introduction from travlers coming from the Eastern US is common. They have not done any economic crop damage in Western Colorado yet, but we need to keep watching. Be especially aware of large numbers of stink bugs overwintering in homes.|

If you are a local honey beekeeper wanting to share or acquire knowledge about beekeeping, please visit the Western Colorado Beekeepers Association website or on Facebook.
The Western Colorado Beekeepers Association has a phone line set up to assist with honeybee swarm removal. In anticipation of the busy season the WCBA has partnered with the Four-Corners Beekeepers to more effectively serve the needs of the public. Due to the terrain of the Western Region, the Four-Corners Beekeepers have agreed to take swarm calls for Archuleta, Dolores, Hinsdale, La Plata, Montezuma, San Juan and San Miguel counties. The Western Colorado Beekeepers will take calls and attempt to partner with beekeepers in the remaining Western Region counties.
If you need assistance with swarm removal contact:
The Western Colorado Beekeepers Association swarm line number
The Four-Corners Beekeepers Association swarm line number is (970) 884-8190. Or visit the FCBA website. They can also be found on Facebook.
