“…We detected several biosynthetic pathways associated with the production of speci c amino acids important for nutrient homeostasis such as carnitine, threonine, and leucine. Although such pathways are not directly classi ed as behavioral or reproductive, some of their metabolic functions have been previously detected in conspeci c experiments in D. melanogaster [28,38]. These networks regulate energy balance [39,40] and nutritional uptake in brain tissues [41], and have been directly linked to several postcopulatory behaviors, including circadian rhythms [42,43], nutrient sensing, exploratory behavior for speci c nutrient source, consumption and posterior oviposition [26,27,75,76].…”
