The U.S. Rangeland Grasshopper Collection contains short-horned grasshopper species from different habitats of the western United States. It is a major resource for the genus Melanoplus (fig. 16) from western North America; of 300 species worldwide, 72 are represented in the collection. This genus contains three of the most economically important species of grasshoppers in the New World.

The 2,900 reprints in the collection's library are worldwide in scope and are primarily on Acridids. Much of the information is now historical, as articles have been continuously added since the start of grasshopper studies in Montana in the late 1920's. The library also contains an archive of correspondence pertaining to grasshopper abatement campaigns that took place between 1900 and 1950.

Background

The collection was started in the early 1920's by Robert L. Shotwell and Steward Lockwood, who were employed by the Bureau of Entomology, U.S. Department of Agriculture, in Billings, MT. Most of the specimens in their collection were obtained in previous surveys throughout the United States by government entomologists. In 1930, the collection was moved to Montana State University. John R. Parker was in charge of the collection, and the laboratory became known as the Grasshopper and Mormon Cricket Laboratory. During this time, Fred Skoog and Louis Spain were the curators, and many specimens were added. In 1961, when the collection was moved to another building at the university, Frank Cowan was in charge of the laboratory. George Hewitt was responsible for the collection from 1970 to 1989. In 1987, the collection was moved to the library in the new Rangeland Insect Laboratory building on the campus of Montana State University. In 1996, the collection was moved to the Sidney Agricultural Research Center, in Sidney, MT, when the Rangeland Insect Laboratory in Bozeman was closed. Jerome Onsager presently serves as curator of the collection. Although the collection has grown slowly since the 1960's, it is used extensively in support of identification services, for historic range records, and as a voucher repository for scientists from the Rangeland Insect Laboratory and many other locations.

Identification
Service

Identifications are made for Federal, state, and private research scientists and for others concerned with pest problems. The collection has been used to assist scientists in locating potential collecting sites for species used in research and is a source of specimens for taxonomic revisions. Information has been made available to movie producers for filming pictures with grasshoppers. In addition to the preserved specimen collection, the laboratory maintains colonies of several important species of rangeland grasshoppers. Live grasshoppers are used for active local research programs and to fill needs as requested by the pest control and motion picture industries, researchers within USDA, and other public agencies and institutions.

Research

The Rangeland Insect Laboratory was located at Bozeman, MT, for over 65 years and was incorporated into the Sidney Agricultural Research Center in 1996. The laboratory is primarily responsible for developing management strategies for insect pests and weeds of rangeland and rangeland-associated agriculture throughout the western United States. The lab is staffed with 5 research scientists, 1 support scientist, and 14 clerical and technical employees. The major emphasis of the laboratory is on crop management of rangeland and rangeland-associated agriculture for the Northern Plains. Studies are performed on biological control (protozoa, viruses, and other pathogens) of insect pests and weeds, insecticide application and delivery, and soil dynamics and hydrology.
