Abstract

Genes conferring insecticide resistance can exert physiological and behavioural side-effects on the phenotypic fitness of their carriers. Previous work has shown that peach-potato aphids (Myzus persicae) possessing target-site resistance to pyrethroids are significantly more refractory to the stimulatory effects of the alarm pheromone (E)-B-farnesene than susceptible insects. The intriguing hypothesis that this leads to selective parasitism or predation of aphid genotypes, thereby constraining the spread of resistance, will be tested at different spatial scales ranging from computer- based analyses of individual components of aphid/natural enemy interactions, to investigations of population dynamics under simulated field conditions.
