CARMA 5.0 (CAse-based Range Management Adviser)

CARMA is a Windows®-based program that produces advice about the most economical responses to rangeland grasshopper infestations in Colorado, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota and Wyoming. CARMA does this by predicting the proportion of available forage that will be consumed by grasshoppers and estimating the economic returns of various treatment options, including newly developed RAATs and Dimilin treatments.

It will allow you to identify 70 of the most common adult grasshoppers.  An identification proceeds simply as this - by choosing more and more features from the list in Characters Available that describe your specimen.

Hopper 4.0

Hopper 4.0 can be used to help determine the best course of action when dealing with grasshopper outbreaks on rangeland. Users should compare recommended treatments with other options developed since the program was written, such as RAATs and Dimilin. Not all treatment options listed in Hopper are currently registered for use on rangeland. Where trade names are used, no discrimination is intended and no endorsement is made by USDA. Although Hopper 4.0 is a DOS based program, it has been modified by USDA-APHIS-PPQ-CPHST to easily install and run on all Windows 2000 and XP machines.
