Abstract
Recent studies in our laboratory have revealed that aphids initiate larviposition in response to plant factors detected before feeding, during penetration of non-vascular tissues. We will investigate the nature of these factors by synchronising electrical recording of stylet activities with video monitoring of parturition, followed by extraction, bioassay and identification of active phytochemicals. The major focus will be on larviposition by polyphagous summer winged females of the black bean aphid, Aphis fabae, with the aim of identifying new larviposition deterrents for this important pest. In addition, comparisons will be made with autumn migratory females, which have an exclusive preference for spindle.
