Wheat Insect Pest Management

Wheat is the largest acreage small grain crop in North Carolina, planted mainly as soft red winter wheat. The most important known yield-limiting insect pests of wheat in the state are the cereal leaf beetle (Oulema melanopus L.), Hessian fly (Mayetiola destructor Say), and aphids (Aphididae), which transmit barley yellow dwarf virus. Management strategies and tactics for these pests are shifting with changing agronomic practices and their effectiveness is mixed. For example, volunteer wheat is important in maintaining Hessian fly populations throughout the year. Elimination of volunteer wheat can reduce population abundance below economically damaging levels (Zeiss 1989, Zeiss et al. 1993). When North Carolina soybeans fields (without a gene conferring herbicide resistance) are planted into no-till wheat stubble, this effective tactic is eliminated as a management tactic.
