Beetles

Posted by John Fulton -

We are still experiencing a large number of beetles in the garden. This includes not only the Japanese beetles, but also the recently emerged Western corn rootworm beetles. These small black and yellow striped beetles are of concern around cucumbers, melons, and pumpkins since they can carry a wilt virus.

It is a good idea to treat your vining crops with Sevin, permethrin, or bifenthrin on a weekly basis. It is important concentrate on the new runners to help prevent damage from squash vine borers.

The numbers of Japanese beetles seem to be declining somewhat. Of course there are still plenty in many areas, but the population should continue to decline until the last of them are finished off by frost. As favored food sources are consumed, less likely plants may be attacked. This may mean a recheck of things around the landscape. I've recently seen them on marigolds, and seen some limited feeding on red maples. These plants are in the less preferred categories.
