摘　　要：应用扫描电镜观察了天蚕（ＡｎｔｈｅｒａｅａＹａｍａｍａｉ），柞蚕（ＡｎｔｈｅｒａｅａＰｅｒｎｙｉ）及种间杂交Ｆ１代卵壳的表面及断面构造。结果表明：Ｆ１代卵壳颜色及形态相似于天蚕，受精孔数目Ｆ１代与天蚕相似为７～１０个，略少于柞蚕。其中柞蚕（♀）×天蚕（♂）卵的受精孔部分排列为２轮，这在昆虫卵中还不多见。卵壳断面大致可区分为３个层次：外层较厚呈海绵状；中层最厚呈片层状，较致密；The surface and seciton of the egg shell of giant silkworm (Antheraea Yamama),oak silkworm (Antheraea Pernyi)and their F 1 hybrids were observed with scanning electron microscope.The results were as follows.The color and shape of egg shell of F 1 generation were similar to those of giant silkworm.The number of micropyles of F 1 generation was 7-10,near to that of giant silkworm and less than oak silkworm.The micropyles on some F 1 generation (oak silkworm(♀)×giant silkworm (♂)) were arranged in two circles,which was hardly observed in any other insects.The section of egg shell was divided into three layers:spongy in the outer layer,lamellar,thicker and denser in the middle layer,thinner and denser in the inner layer.
