Description

Grasshopper infestations of more or less serious proportions have been experienced in South Dakota during the past 10 years. Each fall many questions have been asked the writers concerning the deposit of eggs that was made by the grasshoppers during the growing season just closed and information was sought concerning measures which, if followed, might be effective in destroying the hopper eggs. There are about 112 different species and varieties of grasshoppers in South Dakota. Ordinarily, only four of this number affect our cultivated crops to a damaging extent. These four species are the two-striped, the differential, the red-legged, and the lesser migratory grasshoppers. The two-striped and the differential grasshoppers are robust of body and usually measure between one and one and three-fourths inches in length. The red-legged and the lesser migratory grasshoppers, on the other hand, are smaller, usually measuring less than an inch. These hoppers all live over winter in the egg stage. The eggs are deposited in masses called egg pods. (See more in text.)
