| 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. |
