Effect of Juvenile Hormone agonist on the Accessory Sex Glands of Male Spodoptera mauritia Boisd

Abstract

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.
