Low concentration of pyriproxyfen, the juvenile hormone agonist dissolved in acetone was topically applied on the abdomen of the day 0 pupae (tanned) of male Spodoptera mauritia (Boisd) which is a sporadic pest of paddy to study its effects on the accessory sex glands (ASGs). The ultrastructure of the ASGs dissected out on day 6 appeared non- functional with degenerated epithelium showing large empty spaces, dense granules, condensed chromatin clumps, reduced number of RER and mitochondria in contrast to that of the control.
