夹色姬蜂Centeterus altermecoloratus Cushman是二化螟蛹期的一种有利用价值的寄生性天敌。我们从1979年起,进行了四年的观察,现将所获结果简报如下。越冬据多年调查结果,发现夹色姬蜂以成虫在避风向阳的杂草或枯枝落叶中越冬。代数夹色姬蜂一年发生三代。各代发生期与同代二化螟化蛹期十分吻合。其发育历期与当代日平均温度关系极大。当日平均温度在28℃左右,完成一代最长17天,最短为11天,平均为14天;日平均温度在26℃左
Centeterus altermecoloratus Cushman is a valuable parasitic natural enemy at the pupal stage. We have been conducting a four-year observation since 1979, and the results of the briefing are as follows. Wintering According to many years of investigation, it was found that the Myrmeculaceae winters in adults in weeds or litter of the sunny shelter. Algebra color mosaic Ji bee three generations a year. The occurrence of each generation with the same generation of two pairs of borer pupation period is very consistent. Its developmental history has a great relationship with the average daily temperature. The average daily temperature of about 28 ℃, the completion of a generation up to 17 days, the shortest of 11 days, an average of 14 days; average daily temperature of 26 ℃
