Abstract

Two types of sperm, apyrene and eupyrene, are identified in A. mylitta. The sperm in the adult moth are motionless in seminal vesicles. At the time of ejaculation they received a secretion from male ejaculatory duct that renders them motile. The dissociation of eupyrene bundles, eupyrene sperm motility and the sequence of events of sperm migration in both sexes are described in the present paper.
