鹅膏菌属的蘑菇具有影响动物生存和性能的一系列化学化合物。鹅膏蕈氨酸是在一些鹅膏菌中发现的此类化合物之一。我们研究了鹅膏蕈氨酸及其衍生物蝇蕈醇对5种果蝇（双翅目：果蝇科），双带果蝇、角果蝇、短肾果蝇、移民果蝇和黑腹果蝇的卵蛹存活率、化蛹时间和蛹大小的影响。前三个种都是食菌的，并广泛利用蘑菇进行繁殖，而D。immigrans和D.黑腹果蝇是食果的。我们饲养蝇幼虫的人工培养基与500，250，125，和62.5 μ g/ml的鹅膏蕈氨酸和/或musimol。三种食菌物种不受鹅膏蕈氨酸的影响，而两种食果物种受到影响。在实验中，D.蝇蕈醇的毒性低于鹅膏蕈氨酸。
The mushroom genus Amanita has a spectrum of chemical compounds affecting survival and performance of animals. Ibotenic acid is one of such compounds found in some Amanita mushrooms. We studied the effects of ibotenic acid and its derivative, muscimol, on egg-to-pupa survival, pupation time, and pupal size in five Drosophila species (Diptera: Drosophilidae), Drosophila bizonata, Drosophila angularis, Drosophila brachynephros, Drosophila immigrans, and Drosophila melanogaster. The first three species are mycophagous and use a wide range of mushrooms for breeding, whereas D. immigrans and D. melanogaster are frugivorous. We reared fly larvae on artificial medium with 500, 250, 125, and 62.5 mu g/ml of ibotenic acid and/or musimol. The three mycophagous species were not susceptible to ibotenic acid, whereas the two frugivorous species were affected. In experiments with D. melanogaster, muscimol was less toxic than ibotenic acid.
