“…These dynamics do not seem to be correlated with the e ciency of the biosynthetic pathway of defensive chemicals (Blum 1987;Laurent et al 2005), but instead to be affected by the developmental stage and by food availability -some insects can sequester plant compounds for use in their defense glands (Bowers, 1990; (Whitman et al 1992;Palottini et al 2014). Chemical replenishment in exocrine glands can vary depending on species, sex and developmental stage (Kearsley and Whitham 1992;Rossini et al 1997;Camara 1997;Yu et al 2023).…”

Insects exocrine gland products can be involved in sexual communication, defense, territory labelling, aggregation and alarm. In the vinegar fly Drosophila melanogaster the ejaculatory bulb synthesizes and releases 11-cis-Vaccenyl acetate (cVa). This pheromone, transferred to the female during copulation, affects aggregation, courtship and male-male aggressive behaviors. To determine the time-course of cVa replenishment, males of a control laboratory strain and from the desat1 pheromone-defective mutant strain were allowed to mate successively with several females. We measured mating frequency, duration and latency, the amount of cVa transferred to mated females and the residual cVa in tested males. Mating duration remained constant with multiple matings, but we found that the amount of cVa transferred to females declined with multiple matings, indicating that, over short, biologically-relevant periods, replenishment of the pheromone does not keep up with mating frequency, resulting in the transfer of varying quantities of cVa. Adult responses to cVa are affected by early developmental exposure to this pheromone; our revelation of quantitative variation in the amount of cVa transferred to females in the event of multiple matings by a male suggests variable responses to cVa shown by adults produced by such matings. This implies that the natural role of this compound may be richer than suggested by strictly-controlled laboratory experiments.
