环带锦斑蛾在江西南昌一年1～3代,以幼虫在寄主基部落叶层的叶片内越冬。根据其种群在生活史上的分化,可分为:连续发育型,一年3代;二代滞育型,一年2代;一代滞育型,一年1代。卵聚产于寄主枝秆、叶腋和叶片上。越冬幼虫6～7龄;非滞育幼虫5龄。成虫寿命,雌虫10～15天,雄虫7～10天。讨论了该虫生活史上的~α分散适应”对策的意义。 Ring-belt check moth in Nanchang, Jiangxi 1 to 3 generations a year, larvae wintering in the leaves of the host base deciduous layer. According to its population differentiation in the history of life, can be divided into: continuous development type, three generations a year; second-generation diapause, two generations a year; one-generation diapause type, a generation a year. The eggs aggregate in the host stalk, leaf axils and leaves. Overwintering larvae 6 to 7 years old; non-diapause larvae 5 years old. Adult life, female 10 to 15 days, male 7 to 10 days. This paper discussed the significance of the countermeasure of the dispersion and adaptation of ~ α in the life history of this pest.
