• E-272    Grasshopper Biology and Management. NDSU Extension Circular (web version).

• Orthoptera of the Northern Great Plains by Gerald M. Fauske, NDSU Department of Entomology

The primary purpose of the website is the identification of the Orthoptera occurring in the Northern Great Plains. Every species known to occur in either North Dakota or South Dakota is included within the keys. The Home page gives an overview of this website. Every topic and every page of this site is accessible through the Table of Contents. The Introduction section is simply what this site is about and how to use it. All technical terms used in the text are explained and usually illustrated in the section: Anatomy of a grasshopper.

• Grasshoppers: Their Biology, Identification, and Management  (following this link will exit the NDSU site)
  (USDA-ARS Northern Plains Agricultural Research Laboratory)
     A comprehensive resource for information on grasshopper management that contains the latest research in grasshopper management, identification, ecology and control tactics, including:

  • APHIS’ Grasshopper Integrated Pest Management User Handbook
        This handbook provides practical information on biological and chemical control methods; range management techniques; and environmental impacts. It incorporates decision support tools and an overview of grasshopper ecology, outbreaks and modeling.
  • Field Guide to Common Western Grasshoppers
        This handy guide provides an overview of grasshopper biology, anatomy, populations and life cycles. It also shows how to survey and collect grasshoppers. 
  • Grasshopper Species Fact Sheets
        This collection of 56 species fact sheets features distribution maps and color photographs for each species, as well as information on their economic importance, identification and biology.
  • Grasshopper Identification Tools
        Identification guides, keys, and photographs to help identify over 90 species of grasshoppers. While there are more than 400 known species of grasshoppers in the Western United States, only about two dozen are considered pest species and a few are beneficial.
  • Decision Support Software for Rangeland Grasshopper Management
        Hopper 4.0 and CARMA 3.3 computer software provide advice on the best course of action when dealing with grasshopper outbreaks on rangeland.
  • New Grazing Management Research 
        The latest preventative grasshopper management research on using grazing management to reduce the intensity and duration of grasshopper outbreaks.
  • New Grasshopper Chemical Control Methods (RAATs)
        The latest techniques for reducing application rates and costs up to 50% by alternating untreated swaths with treated swaths. RAATs maintains effective grasshopper control and reduces environmental impact.
  • New Integrated Pest Management Research
        Includes: South Dakota RAATs Demonstration Project Report, North Dakota IPM Demonstration Project Report, Preventative Grasshopper Management Brochure.
