Overwintering aggregations of the leaf-footed plant bug, Leptoglossus australis FABRICIUS (Heteroptera: Coreidae) in Okinawa Island

Abstract

The overwintering aggregations of the leaf-footed plant bug, Leptoglossus australis, were observed on Okinawa Island during February through March, 1985. The aggrega-tions were formed on the withered leaves of the host plant, Luffa cylindrica, and the nonhost plants, Capsicum annuum, Lacluca longifolia, Curia papaya, and Rumex japonicus. Aggregated plant bugs gradually dispersed to fresh host plants from early March.
