Abstract:Since establishment of the Grasshopper Investigations Laboratory at Bozeman, Mont., in 1930, it has been cutomary to maintain a supply of grasshoppers for experimental usage during the winter months. For the most part, eggs were gathered from the field in the fall and kept under refrigeration until needed. Because it was necessary to gather large quantities of eggs, the species of grasshoppers reared were limited to 3 or 4 that normally concentrate their eggs around the edges of cropland or along the horrow pits of country roads. The migratory grasshopper, Melanoplus sanguinipes (F.); the two-striped grasshopper. M. bivillatus (Say); the differential grasshopper, M. differentialis (Thomas); and the clear-winged grasshopper, Camnula pellucida (Scudder), in that order, were the species most sought. In most years we had little trouble gathering sufficient eggs to rear all the grasshoppers needed for experimental work during the winter months. However, with the advent of the chlorinated hydrocarbon insecticides, and their almost universal use on farms to control grasshoppers in and around crops, it became increasingly difficult to find sufficient eggs for rearing the necessary grasshoppers. For this reason we have found it advisable to collect adult grasshoppers during the summer, cage them over sand at the laboratory, ami harvest the eggs. The method has proved quite successful with M. sanguinipes at the Mesa, Ariz., laboratory, where they have been able to obtain enough eggs to supply their needs and also to supply the Bozeman laboratory with several hundred pods each year.
