Egg laying is continuing and larval emergence will continue for up to three more weeks. Development from egg-hatch to pupation takes only two to three weeks. Once the larvae have pupated, it takes another couple of weeks before the new adults emerge. The adults generally do not lay any more eggs and usually do not feed as voraciously as the first group. 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. Aster leafhopper numbers have increased dramatically in both the Portage and Winkler areas. Control measures are likely required in many areas and as numbers appear to be increasing quickly, are likely to be required in virtually all areas within a week. The field scouts observed plants with symptoms of aster yellows. The typical symptoms of aster yellows include stunting of infected plants, purple coloration of older leaves, yellowing of new leaves, and a small pale root.
