Alysia
Alysia is a genus of parasitoid wasps in the family Braconidae. Members of this genus are known to develop as parasitoids within the puparia of dipteran hosts, with at least one species, Alysia manducator, documented to parasitize the blow fly Lucilia sericata. The genus exhibits sex ratio plasticity in response to host size, with larger host puparia producing female-biased offspring ratios. Alysia species function as biological control agents of fly populations.
