Diana Roberts , Darrin L. Walenta ,
Online Only
This bulletin describes how to identify the cereal leaf beetle (Oulema melanopus) and discusses its biology. Scouting techniques and economic thresholds are outlined, along with cultural management methods and optimal times to apply insecticide, if needed. It also discusses the most effective method of control—biocontrol using wasps that only parasitize and kill the cereal leaf beetle. Growers may encourage these free biocontrol agents to multiply in their fields by maintaining a simple insectary. Worksheets and a decision chart are included to help integrate all the decision processes.
