摘　　要：贡嘎蝠蛾卵呈椭圆形，在扫描电镜下卵壳表面分为一般卵壳区和受精孔区：一般卵壳区密布颗粒状突起；受精孔区位于卵端部，呈不规则梨形垫状，精孔开口于突起内侧凹陷上部。贡嘎蝠蛾在6月下旬—7月产卵，散产。在平均温度8－10℃、相对湿度80％－90％，卵的发育历期为50天左右，孵化率75％以上。卵常遭受霉菌和寄生蜂天敌危害。The egg of Hepialus gonggaensis was oval in shape and the surface of chorion under scanning electron microscopy revealed a portion of micropyle which was on the egg crown forming into irregular pear-like pulvinus. The micropyle was in the medial hollow part at the top of pulvinus. The other portion of egg was covered densely by tiny granules.During the last ten days of June to July every year, the eggs were laid dispersively near the host plants. Under 8-10℃ average temperature and 80%-90% relative humidity, the incubation period was about 50 days with an hatching rate over 75%. In egg stage, the ova always endangeral by fungus and natural enemy parasitic wasp.
