摘　　要：鉴别家蚕品种的真实性及检验蚕种杂交率是蚕桑生产的重要工作,但目前生产上还没有一种理想实用的方法。研究发现,采用体视显微镜(解剖镜)放大观察蚁蚕或1、2龄小蚕,不同蚕品种具有不同的蚕体颜色、斑纹、斑纹颜色和形状、体型等形体特征,这种形体特征与4、5龄大蚕的形体特征不同,据此可研究建立根据小蚕期形体特征鉴别家蚕品种及检验蚕种杂交率的方法。The authenticity identification of silkworm breeds and hybrid rate test of silkworm eggs play very important roles in the sericulture production, while there is no ideal and practical method having been applied. The observation by anatomical microscope showed that the body characteristics, such as larval body color, markings and their color and shape and bodily, form of newly-hatched silkworms or young larvae of the 1st and 2nd instar were distinct among different breeds, and different from those of grown larvale of the 4th and 5th instar. On the basis of that a new method can be estabilished for identifying silkworm breeds and testing hybrid rate of silkworm eggs by the body characteristics at the earlier larval stage.
