Many species of beneficial and damaging insects can be found in dry bean fields in the Central High Plains. Recognition of the harmful pests, awareness of threshold numbers required before economic damage occurs, and the proper selection and timing of insecticides are necessary to produce a healthy crop, insure survival of beneficial insects and minimize environmental impacts of the insecticides.

Numerous species of insects feed on bean in the Central High Plains, but only a few species consistently cause serious damage. The major pest species are the western bean cutorm and the Mexican bean beetle. Thrips, seedcorn maggot and grasshoppers can occasionally cause signficant damage to dry beans. Several other pests also occur sporadically.
