Abstract:
Larvae of Drosophila melanogaster were reared aseptically on defined diets containing either cholesterol, campesterol or sitosterol as the only dietary sterol. Sterol analyses of pupae revealed that insects reared on campesterol and sitosterol diets contained 3.3 and 8.1% cholesterol, indicative of an ability to accumulate this sterol. Ecdysone and 20-hydroxyecdysone were the predominant eedysteroids in insects from all diet studies, though makisterone A was detected in pupae reared on campesterol and sitosterol. © 1995.
