Abstract

Nanophyes shoreae (Coleoptera, Apionidae) is a pre-dispersal fruit-predator of dipterocarp trees in South east Asian rain forest These trees frequently abort a large part of their fruitcrop soon after anthesis, coincident with N shoreae oviposition Fruit parameters, related to the incidence of weevil attack, were investigated by examination of fruit collected from host trees and through observations made in the canopy Fruit size and the incidence of prior oviposition determined whether beetles initiated attacks However, many fruits were attacked without oviposition occurring and this is discussed with respect to chemical stimuli
