The level of an organism’s investment in defences against its natural enemies depends not only on the fitness costs of parasitism, but also on the costs of maintaining defences in the absence of infection. The presence of heritable variation in resistance suggests that costs exist, but very little is known about the nature or magnitude of these costs in natural populations of animals. A powerful technique for identifying trade-offs between fitness components is the study of correlated responses to artificial selection. We propose to select the Indian meal moth, Plodia interpunctella for increased resistance against a koinobiont parasitoid, Venturia canescens.  Parasitoid larvae develop internally within the host, resulting in eventual death in the absence of any immune response. Hosts may, however, survive parasitoid attack by investing in a cellular immune response.  We will measure the cost of countering parasitism and the cost of maintaining resistance in absence of immune challenge by measuring the trade-offs between increased resistance and other components of host fitness. We predict that costs of host defences will correlated with fecundity, growth, developmental time, size and/or competitive ability of the resistant lines compared with control lines. This study is especially timely because the proposed host species is a major pest of stored products worldwide while the parasitoid is a potential biocontrol agent. The understanding of factors that determine control of pest species and their evolutionary response clearly requires the marriage of ecological, physiological, behavioral and evolutionary perspectives. Thus, we believe our proposed multi-disciplinary approach to this novel question affecting an economically significant pest is of particular importance

Abstract:

Phoresy is a dispersal mode for inadequately mobile organisms that use carriers. The aim of our work is to study the mechanisms that govern phoresy among three partners: Scarabaeidae beetles – Sphaeroceridae flies – Macrochelidae mites. The diversity of host-phoretic interactions has been analysed, with descriptions of new mite species and the study of two main dispersal strategies: generalist and specialist. Phoresy determination needs precise recognition of the host by the phoretics, with a choice of potential available carriers, and a tendency to specialization which probably favours speciation.       Laboratory experiments (behavioural and olfactometric tests) and chromatographic analyses have been driven to separate visual and chemical stimuli (cuticular products) in carrier discrimination. The host choice is based on chemical criteria for mites, on visual criteria for flies. Dung beetles carry their phoretics to their pedotrophic nest where the mites regulate the number of phoretic flies by predation on eggs and larvae, with, in reaction, a shortening of the fly development length compared to other coprophilous flies.       An analysis of different Macrochelid mite species affinity, using morphological, molecular and behavioural data, shows that the specialized choice of a carrier could appear independently in the different mites lineages.
