The kids will soon be wrapping up their school year, the NHL and NBA are heading toward their respective post-seasons...and the cucumber beetles are preparing to party harder than Paris Hilton.
Overwintering as adults in protected areas near buildings, in fence rows, etc., cucumber beetles become active in mid-spring, when temperatures begin to increase. Eggs are laid and hatched, and the young beetles feed on plant roots.
There are a couple of different varieties in the U.S.: the striped cucumber beetle is an elongated orange insect with distinct black stripes, while the Southern cucumber beetle -- also called the southern corn rootworm, is stubbier, yellower, and wears black spots on its back.
The worst trait of these little beasts is that the organism for bacterial wilt can overwinter in their gut. (Plants infected with baterial wilt will not survive, and should be promptly destroyed, not composted.) The beetle's mere chewing on plants can spread the disease, so it's important to start control early...and be diligent.
Lacewings and ladybugs eat cucumber beetle eggs, so as always, you should welcome those beneficial insects to your garden. Interplanting repellant herbs like catnip, marigolds (the smellier varieties) and nasturtiums can also help. On food crops like zucchinis, cucumbers and melons, use row covers to keep the beetles from reaching the plants.
Lastly, know this: cucumber beetles are tough to kill. Scientists continue to work on organic methods for their control but so far, just like Paris Hilton, they seem content to hang out and mooch.
