Seasonal Occurrence and Voltinism of the Stink Bug, Glaucias subpunctatus（Hemiptera: Pentatomidae）

Abstract

We investigated the seasonal occurrence of the stink bug, Glaucias subpunctatus Walker, using light traps in Kinokawa（34°28′N, 135°41′E）and Minabe（33°82′N, 135°34′E）, Wakayama Prefecture, Japan, in April–October, 2014–2016. We also examined the ovarial development of females. Glaucias subpunctatus females retained developed ovaries from July to early September, and the number of adults caught decreased during this period. Additionally, we caught new-generation G. subpunctatus adults only in the beginning of early August. These results suggest that G. subpunctatus is univoltine in this region.
