The striped cucumber beetle is the most important insect pest of cucurbits i. This insect is responsible for more insecticide applications on cantaloupes than any other pest in Indiana. Both the adult beetle and the immature stages larvae feed on watermelon and cantaloupe.

If you find that the stems of your seedlings are being eaten off, leaves are yellowing and wilting, and holes are appearing, you may have a striped or spotted cucumber beetle problem. Often, the beetles leave their hibernating sites early in the season mid-April to early Juneand feed on seedlings right as they are emerging, usually killing them. Then their larvae feed on the roots of the host plants.

One of the most problematic insect pests that organic vegetable growers have to deal with is the striped cucumber beetle. The insect feeds on all the cucurbit crops, but can be particularly devastating to muskmelons and cucumbers because those two crops are susceptible to bacterial wilt of cucurbits, which is caused by a bacterium carried by the beetles. The only way to avoid this devastating disease is to prevent the beetles from feeding on the plants. There are no effective organic insecticides for managing striped cucumber so we have to look for alternative methods.
William E. This article examines the biology and management of cucumber beetles within organic farming systems. In North American cucurbit crops, two species of cucumber beetle present the most problems.
The three black stripes on the wings have distinct straight edges fig. Beetles sometimes confused with SCB.
