摘要： 在变温条件下连续饲养观察小菜蛾两年，摸清了小菜蛾每年可发生12代，发育起点温度C为2.2℃，有效积温K为613.58日度。测算了每一代每头的平均产卵量。结合当地气温资料对小菜蛾的生长发育、冬季活动状况、全年田间虫口变动趋势进行了分析和讨论。

Abstract: Abstract: Diamondback Moth Plutella xyloslella Linnaeus were reared in natural change temperature for 2 years continuously. There are 12 generations a year. Its threshold temperature (C) was 2.2℃ and effective temperature summation (K) was 613.58 daydegree. The average egg quantity of each female adult in different generations were given. With local meteorological data, the growth and development, activities in winter and population dynamics trend of this insect pest were analysized and discussed.
