CUCUMBER BEETLES IN GARDENS
Cucumber beetles will appear in gardens once the weather warms. Adults don't die but overwinter so as soon as it starts to warm, they come out and can be seen. Adult cucumber beetles will need to feed so anything growing will be fed upon immediately. If you plan on starting a vegetable garden, it's a good idea to treat early cucumber beetle activity which in turn will minimize or even eliminate those that might forage on your crops later in the year. Though cucumber beetles prefer vine plants like cucumbers, squash and pumpkins, they'll eat what they can find early in the growing season. Feeding adults will chew holes through the leaves of new plant growth and they don't discriminate. Active adults will feed on most any garden variety plant they find and their damage can become substantial. More importantly, they are largely responsible for the spread of bacterial wilt. This fungus can be devastating to any garden so don't let cucumber beetle populations have free roam of your plants. Once they feed, males will seek females and mate. Female cucumber beetles will then lay eggs 8-25 days after mating. Females will deposit 225-800 in small egg clusters or singly into soil cracks at the base of cucurbit plants. Eggs hatch 5-8 days later and larvae emerge. These worm like grubs will spend the next 15 days feeding on roots and stems of fruit or anything else close by that is in contact with the soil. The pupal period is 6-7 days for them to molt. The time from egg to adult for the first generation of beetles requires about a month. Over the course of the summer, there could be 2-4 generations and most will take a month or longer to completely grow. After cucurbit plants mature and fall weather approaches, beetles will migrate to wooded landscapes, bushy areas, barns, sheds and houses to find adequate locations to hibernate. Some may overwinter a mile from their original hatching site. Next spring these hibernating adults will emerge as the weather warms and seek new plant growth to feed.
