                                Technical Abstract: Over 20 years ago, a neurohormone, pheromone biosynthesis activating neuropeptide (PBAN), was identified to stimulate sex pheromone biosynthesis in a moth. Since then, the physiological role, target site and signal transduction of PBAN has become well understood for sex pheromone biosynthesis in moths. Despite that PBAN-like peptides (~ 200) have been identified from various insect Orders, their role in pheromone regulation had not expanded to other insect groups. Here, we present PBAN regulation of fire ant, Solenopsis invicta, trail pheromone biosynthesis in the Dufour’s gland (DG). In addition, RNAi knock down of the PBAN gene (in the subesophageal ganglia) or PBAN receptor gene (in the DG) expression inhibited trail pheromone biosynthesis. Reduced trail pheromone was documented analytically and through a behavioral bioassay.
