The third group of pheromone-dependent behaviors
discussed here is the female-specific post-mating behaviors,
which are induced by peptide pheromones [9,10].
These pheromones have two unusual aspects. First, they
are produced in the male reproductive organs and are
transferred to the female during copulation with the
ejaculate (similar to aggregation pheromone); there, they
are taken up into the hemolymph and reach specific sites
in the central nervous system (CNS). Second, they act in a
hormone-like fashion, presumably through neuroendocrine
pathways, that is, their effects are long lasting but
time-delayed.
