Sex pheromones have rarely been studied in parasitoids, and it remains largely
unknown how male and female parasitoids locate each other. We investigated
possible attraction (and repellency) between the sexes of two braconid wasps
belonging to the same genus, the gregarious parasitoid, Cotesia glomerata (L.),
and the solitary parasitoid, Cotesia marginiventris (Cresson). Males of both
species were strongly attracted to conspecific virgin females. Interestingly, in
C. glomerata, the males were repelled by mated females, as well as by males of
their own species. This repellency of mated females was only evident hours after
mating, implying a change in pheromone composition. Males of C. marginiventris
were also no longer attracted, but not repelled, by mated females. Females of
both species showed no attraction to the odors of conspecific individuals, male
or female, and C. glomerata females even appeared to be repelled by mated males.
Moreover, the pheromones were found to be highly specific, as males were not
attracted by females of the other species. Males of Cotesia glomerata even
avoided the pheromones of female Cotesia marginiventris, indicating the
recognition of non-conspecific pheromones. We discuss these unique responses in
the context of optimal mate finding strategies in parasitoids.
