| 摘 要： | 从广州市郊菜地捕捉的甘蓝夜蛾(\%Barathra brassicae L.\%)幼虫体中分离到一种微孢子虫(简称BabM)。孢子呈长卵圆形，大小为：402±036μm×199±036μm；孢子表面抗原与家蚕传统微粒子孢子(\%Nosema bombycis,简称N.b.\%)具共同抗原性；BabM微孢子虫孢子的内部结构、发育的特征与\%N.b.\%孢子相类似。BabM微孢子虫对三龄起蚕感染中量(IC５０)为６０3×１０４粒孢子；经卵传染频率较高。初步阐明了从甘蓝夜蛾分离的这种微孢子虫与家蚕\%N.b.\%同为\%Nosema bombycis\%种，但存在着变异现象。 |

| Abstract: | A microsporidium (called as Bab-M) was isolated from Barathra brassicae L. captured from suburban vegetable plot of Guang Zhou. The spores were long-ovoid in shape and 4.02 +/- 0.36 microns x 1.99 +/- 0.36 microns in size. Immunologically the microsporidium shared spore surface specific antigen(s) with N. bombycis. The ultrastructure and life cycle of Bab-M were similar to that of N. b.. The rate of transovarian transmission was high. The initial conclusion was that Bab-M should be referred to as Nosema bombycis, but there was variation between them. |
