Field Crops Integrated Pest Management

Alfalfa weevil (Hypera postica) adults emerge in the spring and begin feeding on leaves and stems of alfalfa. Female weevils lay eggs in the stem. When the larvae emerge, they feed inside the stem for a few days, and then move on to consume leaf buds and leaves. Severe infestations may require control to reduce economic losses.
