摘　　要：对烟粉虱在番茄地的空间分布型及最适抽样数进行了研究。结果表明:烟粉虱在番茄地呈聚集分布,而且随着密度的增加,成虫的聚集性增强;烟粉虱成虫个体间相互吸引,分布的基本成分是个体群。In tomato field the spatial distribution pattern of B. tabaci and optimum sampling numbers were studied. Results indicated that B. tabaci showed aggregated distribution and its aggregated intensity increased with the improvement of adult density. Attraction existed among B. tabaci adults. The basic distribution component was individual group.
