Volume 61 Number 18 Date 09/01/2016 POTATO LEAFHOPPER - Surveys during the last week of August found very little change in leafhopper populations. Counts were below 1.5 per sweep in all fields sampled in the central and southwestern counties. Levels of this insect have been non-economic all summer long, despite a timely spring arrival and favorable temperatures. Significant population increases are unlikely to occur during the remainder of the growing season. PEA APHID - Representative counts range from 0.3-4.0 per sweep. One alfalfa field surveyed in Richland County contained seven per sweep, the highest population documented in several weeks, but this site was an exception. Pea aphids have been of minor importance since mid-June. -- Krista Hamilton, DATCP Entomologist
