中文摘要:
      本文描述了一种准确、快速鉴定异斑酷大蚕蛾末龄幼虫、蛹和成虫性别的方法。通过对蛹和成虫性别特征比较可知,雌虫生殖孔位于第8和第9腹节,且第8腹节不愈合,雄虫生殖孔仅位于第9腹节上,且生殖孔两侧有瘤状突起。雌性末龄幼虫头壳的蜕裂线附近浅色区域较多,雄性浅色区域较少,且雌性后唇基区域的颜色较雄性更浅。雌雄成虫差异较大,雄虫触角羽状,前翅一般无透明斑或透明斑很小;雌虫为近丝状的羽状触角,前翅有3个较大且连续排列的透明斑。经过对30对雌雄蛹的测量后,发现在蛹长、蛹宽与蛹重等体型数据上,雌雄蛹之间都存在显著性差异(P<0.05)。
英文摘要:
      This study describes a method for accurately and quickly identifying the sex of the Cricula variabilis old-instar larvae, pupae and adults. And it compares the characteristics of adults and pupae, male and female. The female genital pore is located in the 8th and 9th abdominal segments, and the 8th abdominal segment is not closed. The male genital pore is located only on the 9th abdominal segment, and there are lumps on both sides of the genital pore. There are more light-colored areas near the ecdysial line of the female larvae's head shell, and there are fewer male light-colored areas.And the color of the female postclypeus area is also lighter than that of the male. The male and female adults differ greatly. The antennae of the male are pinnately shaped. The forewings are generally without transparent spots, or spots are small. The antennae of the female are short and pinnate which looks like filament, and the forewings have three large and continuous transparent spots. After measuring 30 pairsof pupae, it was found that there were significant differences between the male and female pupae (P<0.05) in the morphological characteristics data such as pupae length, pupae width and pupae weight.
