GRASSHOPPERS OF COLORADO
PREFACE
Grasshopper populations present recurring problems to agriculture in the
western United States, and large sums of money are spent annually to combat
these pests. Those responsible for making decisions about grasshopper control
often lack basic information concerning their target organism. This manual
brings together some pertinent information about grasshoppers. It is intended
for use by Department of Agriculture, Cooperative Extension and university
personnel. Students and others also may find it useful. With this audience
in mind, scientific terminology has been minimized, and a glossary has
been provided.
Although intended for use in Colorado, this manual may be useful for
grasshopper workers in nearby states. Wyoming, in particular, and also
western Nebraska and Kansas and northern New Mexico have similar grasshopper
fauna.
