Rangeland Grasshopper Control Using Dimilin, 1993

Treatment of Pastures with Diflubenzuron Suppresses Horn Fly, Haematobia irritans (Diptera: Muscidae) Development

Diflubenzuron is an insect growth regulator labeled for application to pastures and rangeland to suppress grasshopper (Orthoptera: Acrididae) populations. Livestock are permitted access to land immediately after treatment. We hypothesized the development and survivorship of horn fly Haematobia irritans (L.) larvae feeding on manure resulting from these animals would not be impacted due to the p...

Rangeland Monitoring Using Remote Sensing

Grasshopper (Orthoptera: Acrididae) Community Composition in the Rangeland of the Northern Slopes of the Qilian Mountains in Northwestern China

In order to describe grasshopper (Orthoptera: Acrididae) species composition, diversity, abundance, and density of four rangelands types, we compared the grasshopper community composition and dynamics in the rangeland of the northern slopes of the Qilian Mountains. In total, 55 grasshopper species were collected from 2007 to 2009, representing three families and six subfamilies. The subfamily O...

Study of the Grasshopper Integrated Pest Management Project'

The Grasshopper Integrated Pest Management Project (GHIPM) WDS a S15 million projccllhat lasted from 1986 La 1994 to identify, develop, and implement rangeland grasshopper management tactics within the Framework of Integrated Pest Management (lPI\'I) in the western United Stales. Computer simulation has been used La fulfill many original objectives for GHIPM and help bridge the gap between theo...

Grasshopper Management.pmd

Grasshoppers are divided into two major subgroups: the short-horned grasshoppers (Figure 1) and the long-horned grasshoppers, Mormon crickets and katydids (Figure 2). Short-horned grasshoppers are responsible for most of the reported crop losses. As a result, individuals of this subgroup are popularly referred to as “grasshoppers.” Figure 1. A mature two-striped female grasshopper (Melanoplus b...
