Influence of Stand Composition on Locust Borer (Coleoptera: Cerambycidae) Attack Rates

Abstract

Locust borer attack rates were studied in relation to stand mixtures in Appalachian Maryland. Current (active) attacks, as opposed to past attacks, were utilized to evaluate present stand composition. Current attack density increased with increased percent black locust on the plots. The trend was significant in 2 of 3 study areas (P < 0.05). Current and past attack density were not correlated with each other, nor was current attack correlated with indices of tree thrift or size.
