Abstract: Aiming to determine antifeedant properties or repellent qualities of higher fungi against insects, 71 species of mushrooms and toadstools were screened using Spodeptera littoralis as a model insect. Reference tests were performed by offering an isolated larvae choising between a fungus-containing rearing medlium and a reference one. Among the 71 fungal species screened, 24 were fo und to show anti feeding or repellent properties as they were significantly rijected compared to the reference medium. A table of rejection of fungi by Spodetera ldtoralis is provided.

摘要： 为确定高等真菌对昆虫的驱避及拒食作用，笔者以黑腹果蝇（Spodo pters littoralis）为样虫，对71种蘑菇包括毒蕈进行了筛选。通过隔离的幼虫在含菌饲料及对照饲料之间的选择来进行食物驱避及拒食试验。在所试71种中，与对照饲料相比较，有24种对昆虫表现出明显的拒食及驱避作用。
