Colorado potato beetle larvae are generally in the later instars now. Some may have entered the soil to pupate and the second group of adults will emerge in two to three weeks. They will feed for a brief period then leave the fields to overwinter. No new eggs will be laid by this group of adults. Aside from potato, the beetle readily attacks eggplant and tomato.
Numbers are low compared to other years but they are capable of laying numerous eggs.
They feed on a wide variety of vegetables including cole crops, many of the oriental vegetables, radish and rutabaga. No larvae have been detected yet. The relatively dry, mild weather over the past few days will help to slow disease development. All crops should be scouted carefully to detect diseases that are present. The warm wet weather that was experienced a few weeks ago was favorable for the development of bacterial diseases, and many have been observed on a variety of vegetable crops.
