Biological crop protection: a new 'slow down/speed up' strategy for aphid management

This project will underpin the development of a ‘slow down / speed up’ integrated pest management (IPM) system for aphid pests of field crops that combines plant breeding and biological control, focusing on the peach potato aphid, Myzus persicae. Our approach involves slowing down the growth rate of pests while speeding up the performance of their natural enemies. We are investigating the hypothesis that Brassica genotypes with partial resistance that slows down aphid development makes the pest more susceptible to biological control agents including biopesticides and parasitoids.
