摘　　要：[Objective] The aim was to explore the morphological characteristics of ovum from Spodoptera exigua and Heliothis assulta.[Method]The ultra morphological characteristics of ovum was observed with scanning electron microscope（SEM）.[Result]The ova from S.exigua and H.assulta are all spheroid,the former has net line decoration on surface,with some aeropyle distributed on the net line decoration;the micropyle is located in the center of polar and has plum flower-like engraving;the surface of chorion of the latter has the parallel crowns through two polar.Between the parallel crown,the surface of chorion has the decorated trapezium line,all crowns of second polar zone have breast-tuber that distributes in parallel at the same latitude in line,and there is no aeropyle distributing on chorion.[Conclusion] The ultra morphological characteristics of the ova from two Noctuidae species showed significant difference to each other,which enriched ontogenesis data and also provided reference for the accurate identification of two kinds of ova.[目的]探索甜菜夜蛾和烟青虫卵的形态学特征,为卵的发育及种群鉴定积累资料。[方法]运用扫描电子显微镜对两种昆虫卵的超微结构特征进行观察。[结果]甜菜夜蛾和烟青虫的卵均为球状,前者卵壳表面具网状纹饰,且分布有较多的呼吸空,卵孔外围的梅花状刻纹卵石状;后者卵壳表面隆起贯穿两极,隆起间具梯形纹饰,亚极区的隆起上分布有乳突,未见呼吸孔的分布。[结论]甜菜夜蛾和烟青虫卵的超微结构特征存在种间特异性,超微特征丰富了两种昆虫的个体发育资料,也为两种昆虫的卵及其外类群的准确鉴定提供参考。
