用自然变温法测定细毛蝽卵的发育起点温度(C)为12.1±0.4(℃),有效积温(K)为72.1±4.0(日度);1981——1982两年间用垂直(系统)调查和水平(同期)调查相结合的方法研究烟田细毛蝽成虫的分布型,其结果是:在一类田基本上是负二项分布,二类田多为负二项分布和奈曼分布共存的型式;初步分析这样的分布型式乃是细毛蝽成虫聚集和取食的选择习性与烟株长势共同作用的结果;根据有虫株率X与百株虫量Y之间有极显著的(r=0.9771)直线相关,建立了百株虫量平方根Y′(=y~(1/2))对着虫株率反正弦X′(=Sjn~(-1)X~(1/2))的回归方程式;即:Y′=-0.5326+0.2793X′。
The onset temperature (C) of the eggs of M. sturgeon was 12.1 ± 0.4 (℃) and the effective accumulated temperature (K) was 72.1 ± 4.0 (day) by natural temperature method. From 1981 to 1982, the vertical (systematic) Level (contemporaneous) survey of the distribution of adults in the field of Microtus oeconomus, the result is: in a field is basically a negative binomial distribution of the second field mostly negative co-existence of the binomial and Neiman distribution The preliminary analysis of such distribution patterns is the result of the interaction between the selection habits of adults and the growth of tobacco plants; 0.9771), and the square root of the number of insects was established. The square root of Y ’(= y ~ (1/2) Regression equation; that is: Y ’= - 0.5326 + 0.2793X’.
