Abstract

\r\n Kentucky is surrounded on all sides by invasive insects of importance to field crops. Specifically we are interested in two groups of pests of corn and soybean. The “variant” western corn rootworm, Diabrotica virgifera virgifera LeConte, is spreading eastward and southward in Illinois and Indiana. This insect has become a pest of first year corn by overcoming rotation as a control. The pest has succeeded in this through adapting the behavior of laying eggs in soybeans in a year preceding corn production. Two stink bugs that are of importance to corn and soybean production are found in adjacent states. The brown marmorated stink bug, Halyomorpha halys (Stal) is known to be present in bordering states of IL, IN, OH, WV, VA and TN while the red banded stink bug, Piezodorus guildinii (Westwood) is known to be present in TN and MO. Our objectives in this study are twofold: (1) early detection of the invasive pests and (2) developing a robust data set describing the current pest situation. In 2010 twelve counties were surveyed. None of the targeted invasives were collected. Data were obtained on three species in the brown stink bug complex, two species in the green stinkbug complex and a single predatory species. Estimates were made on relative frequencies and sex ratios. These serve as baseline data prior to entry of the invasive species.
