Testes or the isolated sheaths of testes from late-last-instar larvae of the tobacco budworm, Heliothis virescens, spontaneously secreted ecdysteroids in vitro. Exogenous 20-hydroxyecdysone, incubated with the testes or isolated testis sheaths, functioned in a local positive feedback system to incre
