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 ecdysteroids in insects from all diet studies, though makisterone A was detected in pupae reared on campesterol and sitosterol.
黑腹果蝇幼虫在无菌条件下饲养于特定饮食中，这些饮食分别含有胆固醇、菜油甾醇或谷甾醇作为唯一的膳食甾醇。对蛹进行的甾醇分析表明，以菜油甾醇和谷甾醇为饮食饲养的昆虫体内含有3.3%和8.1%的胆固醇，这表明它们有积累这种甾醇的能力。在所有饮食研究的昆虫中，蜕皮激素和20-羟基蜕皮激素是主要的蜕皮甾体，不过在以菜油甾醇和谷甾醇饲养的蛹中检测到了马氏酮A。
