Research Project: IPM of Black Grass Bugs

Agriculturists in Wyoming and several other western states (Idaho, Utah, Colorado, Nebraska, New Mexico, Arizona, Oregon, and Washington) are facing an unprecedented increase in rangeland damage by black grass bugs (BGB) (Hemiptera: Miridae). Aggravated by continuing drought, this damage is most severe on improved grasslands enrolled in the Conservation Reserve Program (CRP), which covers over 6 million acres in these states. The affected grasslands rapidly deteriorate, losing their value as wildlife habitat. The BGB infestations often spread from grassland to adjacent wheat fields, causing significant crop losses. 

In the past, no management efforts to reduce BGB populations have been implemented on CRP. Recent increased flexibility in CRP management offers more opportunities for Integrated Pest Management (IPM) techniques. The objective of this field-oriented, multi-disciplinary project is to develop an integrated strategy for sustainable BGB management in CRP grasslands to protect ecosystem health and biodiversity, and support agricultural producers. It will be based on assessment of BGB infestations through remotely sensed/GIS and ground survey techniques. Action thresholds will be derived from BGB phenology and density/plant damage relationship. Potential management approaches include livestock grazing, mechanical harvesting, and insecticide applications. These strategies may be applied separately or combined in an IPM approach. Management options will be evaluated for their efficacy, economic efficiency and environmental risk reduction.
