Abstract

The proportion of fruiting to non-fruiting clusters on apple trees influences the distribution of predators within and between trees. The mirids Atractotomus mali (Meyer), Campylomma verbasci (Meyer), Hyaliodes harti Knight, Diaphnocoris pellucida (Uhler), Pilophorus perplexus Douglas and Scott, and the anthocorid Anthocoris musculus (Say) all showed greater preference for limbs (or trees) bearing a high proportion (or percentage) of fruiting clusters. The predacious mite Anystis agilis Banks exhibited no preference.
