Management of Mexican Bean Beetle in Snap Beans Using Cultural Control Strategies

2015

Mexican bean beetle (Epilachna varivestis Mulsant) is a serious pest of snap bean varieties, causing injury by feeding on the leaves and pods and increasing the chances of diseases while making the pods unmarketable. Researchers at Virginia Tech have taken a special interest in finding sustainable methods for controlling the insect; snap beans are an important fresh market crop in the state, with over 5,500 acres grown.

These series of fact sheets from Virginia Tech discuss cultural control strategies of the pest that could alleviate reliance on chemical foliar applications. Such strategies include plastic mulches to reduce insect populations and feeding damage, more resistant snap bean varieties, parasitoids, and delayed planting.
