What is Alfalfa Weevil Management in Utah about?

1) The alfalfa weevil has one generation per year and is a major pest in Utah and the Intermountain West. 2) Larvae feed on alfalfa leaves in the spring, causing the most damage near the first cutting if populations peak during the last larval stage. 3) Natural enemies like parasitic wasps can provide some control of alfalfa weevil larvae, but their effectiveness is highly variable so insecticides may be needed if monitoring shows larval populations exceed economic thresholds.
