What are cucumber beetles?
Cucumber beetles can be a pest of cucurbits and other vegetables (Table 1) in the home garden. In east central Utah, zucchini, cucumber, and cantaloupe have received the most damage. In some cases, the leaves of these cucurbits have been riddled with feeding holes. Cultural practices and avoidance of planting highly susceptible cucurbit varieties are the major recommendations for the home garden. Use of row covers, mulches, hand removal of beetles, and crop residue destruction in the fall can reduce cucumber beetle populations and crop damage. If there is a history of cucumber beetle problems in the area, planting non- and less preferred cucurbit species and varieties (see lists above) can help the home gardener avoid beetle infestations. Also avoid using broad-spectrum, toxic insecticides to preserve natural enemies that help suppress cucumber beetles.

What are the predators of cucumber beetles in Utah?
Natural predators and parasitoids that attack cucumber beetles in Utah include ground beetles, soldier beetles, braconid wasps, tachinid flies, and entomopathogenic nematodes (Fig. 10). Nematodes can suppress cucumber beetle larvae and pupae in the soil while the others will attack adults, eggs and larvae on plants or on the soil surface. Natural populations of these beneficial agents can be preserved by avoiding the use of broadspectrum, toxic insecticides and enhancing crop and soil health through cultural practices. Purchase and release of natural enemies from commercial suppliers has not proven effective for cucumber beetles.
What are the diseases caused by cucumber beetles?
Both species will vector plant diseases (Table 1). Bacterial wilt, caused by Erwinia tracheilphila, overwinters in the bodies of hibernating beetles and is a major problem in central and eastern U.S., but not in the West. In Utah, squash mosaic virus, vectored by both species of cucumber beetles, is a greater concern. Aphids are the primary vector and the virus is also seed-borne. Use of certified seed and suppression of aphid and cucumber beetle populations when they occur are the primary tactics to manage squash mosaic virus. Virus symptoms include mosaic patterns, leaf mottling, ring spots, blisters, and fruit deformation (Fig. 8).

How do cucumber beetles live?
Adult cucumber beetles overwinter in the garden, in compost piles or in trash heaps, then emerge in spring. 1 The adults feed on weeds and other plants until their preferred food source—cucurbits (such as cucumbers, squashes, and melons)—are available. Once the beetles locate cucurbits, they feed on the plants and the females lay their eggs in the surrounding soil. After the eggs hatch, the larvae (now called rootworms) feed on below-ground cucurbit roots and stems until they pupate. Then, the adult insects emerge from the pupae and the cycle starts all over again.
How to kill cucumber beetles?
There are a number of environmentally friendly ways to control cucumber beetles: 1 Protect young cucurbit seedlings from cucumber beetles by covering them right after planting with floating row covers, individual screens, or cones. 2 Try planting cucurbits later in the season.

Adult beetles found on plants can be hand-picked and squished. 4 Mulch the ground with straw, hay, plastic, or fabric to deter cucumber beetles from laying eggs in the ground near the plants; however, this will not eliminate them entirely.
