HISTOLOGY OF THE FEMALE SEX PHEROMONE GLAND OF THE SAPODILLA FRUIT BORER (LEPIDOPTERA: PYRALIDAE)

 

JINTAMAS SUWANJARAT AND BOONGEUA WITETHOM

ABSTRACT: The sex pheromone gland of the calling female sapodilla fruit borer(SFB), has been studied histologically. The scent gland is located dorsally and ventrally in the intersegmental membrane between the eighth and ninth segments. The gland is histologically similar in adult female from 1-7 days old. The gland of every moth was composed of a single layer of columnar epithelial cells with round or oval basal nuclei. No vacuoles are seen in the cytoplasm. The external surface of the pheromone gland is covered by minute cuticular spines.
