Variation of Leptopilina boulardi success in Drosophila hosts: what is inside the black box?
Interactions between Drosophila hosts and parasitoid wasps are among the few examples in which occurrence of intraspecific variation of parasite success has been studied in natural populations. Such variations can originate from three categories of factors: environmental, host and parasitoid factors. Under controlled laboratory conditions, it is possible to focus on the two last categories, and, using specific reference lines, to analyze their respective importance. Parasitoid and host contributions to variations in parasite success have largely been studied in terms of evolutionary and mechanistic aspects in two Drosophila parasitoids, Asobara tabida and, in more details, in Leptopilina boulardi. This chapter focuses on the physiological and molecular aspects of L. boulardi interactions with two Drosophila host species, while most of the evolutionary hypotheses and models are presented in Chapter 11 of Dupas et al.
