摘    要:对烟粉虱Bemisiatabaci成虫在单株茄子(SolanummelongenaL.)、西瓜(CitrullusvulgarisSchard)和甜瓜(CucumismeloL.)上的分布规律及其空间分布型进行了研究。在植株上中部较幼嫩且已充分展开之叶片上烟粉虱成虫数量最多,成虫呈聚集分布。成虫在黄瓜(CucumissativusL.)上亦呈聚集分布,确定了不同虫口密度情况下的最适抽样数。

关 键 词:烟粉虱  空间分布型  最适抽样数

Abstract:Distribution characteristics of Bemisia tabaci adults on the single eggplant, watermelon, and muskmelon and the spatial distribution pattern of B. tabaci on these plants were studied. On the upper, tender and fully open leaves, the number of adults of B. tabaci was the most. The distribution of B. tabaci adults was a aggregation distribution., on above plants as well as the cucumber and the optimum sampling number was determined in different adult densities.
Keywords:Bemisia tabaci  spatial distribution pattern  optimum sampling number
