摘要: 1. There was a positive correlation between oviposition and feeding preferences offspring performance in the spittlebug Aphrophora pectoralis Matsumura (Homoptera: Cercopoidea, Aphrophoridae) on four species of willow Salix sp. (Salicaceae) growing near Sapporo, Japan. Spittlebugs preferred rapidly shoots where highest. 2. When effects shoot length were removed, egg densities associated with three species. Egg survival rates low integra miyabeana. Survival high sachalinensis, which had densities, hultenii, densities. 3. formed mating aggregations almost exclusively S. sachalinensis but then dispersed to other oviposit. 4. Nymphs from site feed nearby within same plant they did not disperse plants. preference for as ovipositing females, so able refine maternal choice by moving larger eclosed. 5. The spittlebugs highly aggregated at all life stages that even only small proportion most vigorously utilised.
