|Grasshopper Site Highlights|
Please note: We are in the process of updating our existing grasshopper site to make it mobile friendly. To start that process we've moved over our grasshopper hazard maps (1994-2019) and survey maps to the new site. Until the update for the entire site is completed you will be redirected between the old and new websites. We apologize for the inconvenience.
This website provides one of the most comprehensive sources of information on the biology, ecology, identification and management of grasshoppers and Mormon crickets in North America. It also contains information on non-target effects, current survey information, and decision support software. The site was produced by the USDA-ARS-Northern Plains Agricultural Research Lab in Sidney, Montana, and several collaborators.
Grasshopper Identification Guides and Species Fact Sheets - Several identification guides, keys and a naturalist's guide are provided to help identify grasshopper species throughout North America and to provide information on the biology and economic importance of individual species. Fact sheets, with photographs, for 60 common species.
Field Guide to Common Western Grasshoppers - An overview of grasshopper biology, ecology, anatomy, life cycles and surveys.
Grazing Management and Grasshoppers - Grazing management methods to help reduce grasshopper outbreaks.
Chemical Control Methods - New aerial and ground based techniques (RAATs) for reducing pesticide application rates, costs, and environmental concerns.
Grasshopper Management Information - Includes practical grasshopper management guides, USDA-APHIS grasshopper control program information, environmental side-effects of grasshopper control, and IPM and chemical control research reports.
Outbreak Information - Regional hazard maps for the Western United States and updated grasshopper and Mormon cricket outbreak field survey and forecast information.
APHIS' Grasshopper Integrated Pest Management User Handbook - Practical information on grasshopper control methods, environmental impacts, range management techniques, grasshopper ecology, outbreaks and modeling.
NPARL Grasshopper Management Research and Publications - An overview of grasshopper and Mormon cricket research being conducted at USDA-ARS Northern Plains Agricultural Research Laboratory (NPARL) and a list of grasshopper publications.
