Abstract

Grasshoppers in Iowa are now dying from infection by several insect pathogens. These pathogens are causing disease that may devastate grasshopper populations in corn and soybean fields before the first frost. Entomophaga fungus is a widespread and common pathogen of grasshoppers in North America. The advanced stage of the disease is easy to recognize. Shortly before the grasshopper dies, it climbs to the top of a fencepost, cornstalk, or other plant where it hangs on in a death grip. It typically dies with its head pointed upward and the carcass often remains in this position for several weeks until it deteriorates.
