Butterflies as hosts

Organized by

Anne Duplouy

Lepidoptera are the host species of an extremely large range of organisms, from endo- and ecto-parasitoid wasps, pathogenic fungi and viruses, to endosymbiotic bacteria exhibiting phenotypes in the spectrum between parasitism and mutualism. Such interactions are most likely to have great repercussions on different aspects of the biology of the butterfly hosts. The consequent co-evolutionary arm races might, indeed, lead to modifications in the hosts’ immune strategies, fecundity, behaviours and other life-history traits, or genetics.

As many Lepidoptera species are the hosts of specific parasites, parasitoids and/or symbionts, it is critical we acknowledge their presence and importance in shaping the host biology. This symposium will aim at presenting some of the many interactions, and their consequences on the host species, for a more accurate understanding of the Lepitopteran taxon.
