| 摘 要： | 为寻找新的生物灭蚊资源，我们用九株菌株的孢子液作杀灭致倦库蚊早三龄幼虫的实验。其中Ｍ．ＳＰ．ＧＹ，Ｐ．ｆａｒｌｉｎｏｓｕｓ１０２０和Ｐ·ｆｌｕｍｏｓｏ－ｒｏｓｅｕｓ８０７８引起的蚊虫死亡率分别可达７５．１±２３．５％、５８．６±３８．８％和５９．３±１９．８％。从Ｐ·ｆｌｕｍｏｓｏ－ｒｏｓｅｕｓ８０７８感染致死的蚊幼虫中又分离出该菌，培养后产生的分生孢子仍具有较高的蚊虫致死率。Ｍ．ｓｐ，ＧＹ和Ｐ·ｆａｒｌｉｎｏｓｕｓ１０２０的孢子冰冻匀浆能在较短时间（１～２天）内使蚊虫死亡，表现出明显的真菌毒素作用。

| Abstract: | Bioassay was conducted to test the effects of entomophagous on Culex quinquefasciatus larvae. These fungi were Metarhizium anisopliae var. anisopliae 3 305, M. anisopliae var. major 3 401, M. sp. GY, Beauveria bassiane 9 139, B. bassiane 101, B. brongniarlii, Paecilomyces farlinosus 1 020, P. flumoso-roseus 808, P. flumoso-roseus 8078. Among them, M. sp. GY., P. farlinosus 1 020 and P. flumoso-roseus 8 078 caused higher larval mortality than of the control. Blended spore supension of M. sp. and P. farlinosus 1020 after being frozen caused even higher mortality. P. flumoso-roseus 8 078 was reisolated from larval cadavers. The spores of it also had the ability to kill the mosquito larvae. |
