For grasshoppers, habitat management practices such as grazing and fire will be used to minimize variation in grasshopper populations around lower average densities. The reciprocal interactions among grasshoppers and plant communities will also be investigated. The efficacy of existing microbial agents for grasshoppers will be improved to make rangeland application practical. The environmental cues and behavioral interactions that drive Mormon cricket migratory bands will be investigated. Safe and effective natural enemies for the wheat stem sawfly will be developed and released. Sugar beet root maggot management will be developed that integrates microbial control with other control strategies.
