- The oogenesis-flight syndrome reflects the temporal allocation of energy resources between dispersal / migration and reproduction and is a key concept in research on migratory behaviour in animals. Here, we used an experimental set-up to assess how variation in host plant abundance affected the activity of regulatory elements in the painted lady butterfly (Vanessa cardui), a model species for insect migratory behaviour studies. The results indicate that recently eclosed females that had access to host plants invested in reproduction at an earlier stage and that variation in host plant abundance triggered significant differences in regulatory element activity via acetylation. By analysing functions of genes in the vicinity of significant differences in regulatory activity we pinpointed a set of categories that can be relevant for how females perceive the environment and allocate resources for either migration or reproduction. The functions of genes in the vicinity of differentially activated regions were associated with metabolism, egg shell formation, female receptivity, muscle activity, pheromone binding and mini-chromosome maintenance. Our results provide a first glimpse into the regulatory underpinnings of the oogenesis-flight syndrome and a starting point for more detailed understanding of the links between environmental variation, gene regulation and migratory behaviour in butterflies.
