| Abstract: | We have isolated and characterized cDNAs representing two distinct pheromone binding proteins (PBPs) from the gypsy moth,
Lymantria dispar. We use the L. dispar protein sequences, along with other published lepidopteran PBPs, to investigate the evolutionary relationships among genes
within the PBP multigene family. Our analyses suggest that the presence of two distinct PBPs in genera representing separate
moth superfamilies is the result of relatively recent, independent, gene duplication events rather than a single, ancient,
duplication. We discuss this result with respect to the biochemical diversification of moth PBPs.
