Termites are xylophagous insects well-known for their hierarchical organization and labour division between individuals which has permit them to be defined as eusocial insects.
The latter organization is based on a highly optimized cast system. Workers take care of the colony by foraging, feeding other casts individuals and taking care of the brood but can also develop into neotenic reproductives. Soldiers defend it against predators and other biotic pressures. Nymphs are morphologically characteristic individuals that will become preferentially reproductive. Lastly, termites of the reproductive cast have a capital role in the colony as they’re the only ones able to mate and lay eggs. They maintain the survival of the colony. Thus this reproductive cast have a key role in every termite species dynamics.
In this thesis project we are investigating the behavioral ecology and genetic of reproductive individuals from two European species, one endemic and one invasive species. The purpose is to understand the different factors of differentiation of the three reproductive kinds (primaries or alates; secondaries or neotenics from two kinds, nymphoids and ergatoids). To do so, we are working with several approaches based on behavior observations, morphometric plasticity, chemical analyses and behavioral genetics.
