[目的]棕斑澳黄毒蛾Orvasca subnotata Walker是于降香黄檀Dalbergia odorifera T. Chen人工林中新发现的一种食叶害虫,其生物学特性描述和龄期判定是虫害预测预报与林间防治的重要依据。[方法]本研究通过定期林间采样的方法,对棕斑澳黄毒蛾不同发育阶段的形态特征及生活史和生活习性进行调查;并通过测量头宽、前胸毛瘤宽和体长3项分龄指标,测定棕斑澳黄毒蛾幼虫的龄期。[结果]本文报道了棕斑澳黄毒蛾不同发育阶段的形态特征、生活史和生活习性。研究结果表明,棕斑澳黄毒蛾幼虫随龄期增长,前胸逐渐变黑,腹部背线和翻缩腺颜色逐渐加深,特征逐渐变得明显。通过频次分析统计,测得棕斑澳黄毒蛾幼虫龄...

[Aim ] The moth Orvasca subnotata Walker（ Lepidopetra： Lymantriidae） is a severe defoliator of Dalbergia odorifera T. Chen found in man-made forests,and its biological characteristics and the determination of its larval instars are the important basis for the pest forecast and control in the forest.[Methods]The morphological characteristics,the habit of each developmental stage and the life history of O. subnotata were investigated though regular field sampling. Through regular forest sampling and morphological characterization,three indicat...
