Pre-imaginal conditioning alters adult sex pheromone response in .

Pheromones are chemical signals that induce innate responses in individuals of the same species that may vary with physiological and developmental state. In , the most intensively studied pheromone is 11--vaccenyl acetate (cVA), which is synthezised in the male ejaculatory bulb and is transferred to the female during copulation. Among other effects, cVA inhibits male courtship of mated females.
