CSU officials: Grasshopper outbreak is possible this year in northeast Colorado
There’s a greater than normal risk for outbreaks of grasshoppers in northeast Colorado this year, according to Assefa Gebre-Amlak and Frank Peairs with Colorado State University Extension.
The highest risk of an outbreak is in Yuma and northern Kit Carson counties, but other counties with more localized spots of high risk include Washington, Morgan, Logan, Lincoln, El Paso and Weld. Weather conditions will determine how much of the outbreak potential will be realized.
The two extension specialists said that while there are more than 100 different species of grasshoppers in Colorado, only about a dozen are considered important on rangeland, while there are five species which cause the most problems on crops.
