| 摘 要： | 草地贪夜蛾入侵我国云南西部地区后,在田间与斜纹夜蛾混合发生。由于二者寄主种类、发生规律和形态特征十分相似,给调查和测报工作带来了很大的困难。对草地贪夜蛾和斜纹夜蛾的形态特征观察发现,草地贪夜蛾卵块鳞毛较为疏松,且单块卵量明显少于斜纹夜蛾;草地贪夜蛾幼虫头部有白色Y纹,第8腹节具方形黑点,而斜纹夜蛾幼虫亚背线内侧各体节均有1对三角形黑色斑纹,且第1腹节和第8腹节较大;草地贪夜蛾蛹臀棘无倒钩或弯曲,而斜纹夜蛾臀棘末端有弯曲或倒钩;草地贪夜蛾成虫体型小于斜纹夜蛾,其雄蛾前翅环形纹黄褐色、肾形纹灰褐色、剑状纹不明显、顶角具较大的白色块斑,而斜纹夜蛾雄虫前翅环形纹白色、外横线与亚缘线间具泛紫色斑纹、剑状纹明显。和斜纹夜蛾相比,草地贪夜蛾大龄幼虫具有明显的自残习性。除此之外,两种害虫的迁飞、交配、繁殖等生物学习性有较高的相似度。本文的研究结果为草地贪夜蛾和斜纹夜蛾田间卵、幼虫、蛹和成虫密度监控工作提供了技术支持。
