What is Modelling the interactions between phenology and insecticide resistance genes in the codling moth Cydia pomonella about?
## Abstract In the codling moth __Cydia pomonella__ (L), insecticide resistance genes have been associated with pleiotropic effects affecting phenology. In this paper, we investigated whether an increase in the frequency of insecticide resistance in field populations of __C pomonella__ was likely to entail significant divergences in the temporal occurrence of both susceptible and insecticide‐resistant individuals. For this purpose, we built a phenological model that provided suitable predictions of the distinct and diverging seasonal evolutions of populations of a susceptible and two insecticide‐resistant (at two and three loci) homozygous genotypes of __C pomonella__. Model simulations for each genotype were further compared with pheromone trap catches recorded in a field insecticide‐treated population over an 8‐year period (from 1992 to 2000), which reflected the progressive annual increase in the frequency of resistance in southeastern France. We found a significant delay in field adult emergence relative to those predicted by the homozygous susceptible model, and the magnitude of such a delay was positively correlated with increasing frequencies of insecticide resistance in the
