Many different insects attack leguminous vegetables. Aphids damage terminals, whiteflies feed on sap and transmit bean golden mosaic virus, and caterpillars, like bean leafroller, and beetles feed on leaves. Flower thrips feed in blossoms and stink bugs, corn earworm, and leaffooted bugs damage seeds and pods.

Snap beans are becoming an important crop for Florida. Southern peas (a bean) are common in north Florida. Many other types of beans are grown on a small scale. Increasingly, newer pesticides are being registered for the entire crop group, including legumes such as pigeon pea, yardlong bean, swordbean, and crowder pea. Labels for individual insecticides should be consulted to see if they are labeled for all types of beans.

According to already published guidelines for snap beans (Pernezney et al., 2003) management practices should include scouting twice a week for insect pests in at least one location for every 2.5 acres. More sites should be chosen in small fields (less than 20 acres). A map of the field should be drawn so that pest counts can be connected to a particular section of the field for future reference.
