于2017年5月中下旬，从湖南省长沙市岳麓区、湘乡县的天然原始次生枫香树林暴发枫毒蛾林区采集枫毒蛾（Lymantria nebulosa Wileman）幼虫，于室内饲养，观察记录枫毒蛾幼虫不同发育阶段的形态特征及发育情况。结果表明：枫毒蛾幼虫虫体可视毒毛随着龄期增加而逐渐增多，翻缩腺颜色逐渐加深；随龄期增加，枫毒蛾头宽、体宽及体长均显著加大，其中头宽可作为枫毒蛾幼虫最佳的分龄指标，体长和体宽可作为辅助指标；在27 ℃的饲养条件下，枫毒蛾幼虫龄期为7龄，完成1个世代约需66.7 d，成虫雌、雄比为0.965 5，单雌产卵量为（330.43±27.801）粒。

Lymantria nebulosa (L. nebulosa) Wileman larvae were collected from the natural secondary forest of maple tree in Yuelu District in Changsha and Xiangxiang of Hunan province at mid-late May 2017, and raised indoor. The morphological characteristics and the developmental stages were observed and recorded in the laboratory. Our results showed that the larvae visual toxic burrs gradually became bigger and poison gland color gradually deepened; the head capsule width was considered as the best index and the body length and body width could be used ...
