山东省发现二点委夜蛾近似种一双委夜蛾

摘要

2012－2013年先后在山东威海玉米田和德州杂草下发现了一种与二点委夜蛾[Athetis lepigone （Möschler）]幼虫和成虫形态相似的近似种，与二点委夜蛾混合发生，后经中国科学院武春生博士鉴定为双委夜蛾[Athetisdissimilis（Hampson）]，本文将其形态特征和生物学特性进行简单描述，比较了与二点委夜蛾形态学上的差异，为进一步研究双委夜蛾提供参考。%Morphologically alike species of Athetis lepigone (Mö schler),which had the same habitat to A.lepigo-ne was found in Weihai and Dezhou of Shandong Province in 2012 and 2013. It was further identified as Athetis dissimilis(Hampson)with the help of Dr. Chunsheng Wu from Chinese Academy of Sciences. The morphological characters and biology of A.dissimilis was described and compared the difference with A.lepigone in morpholo-gy. The results will be helpful for further research of A.dissimilis.
