摘要
对南美斑潜蝇在蚕豆上分布调查表明 ,该虫在蚕豆上的空间分布图式是聚集分布 ,分布的基本成分为个体群。并得出各个虫态的最适抽样数模型 ,即 :卵N =(6 .6 35 6 /m +0 .0 6 17) /D2 ,幼虫N =(0 .0 35 2 /m +0 .6 373) /D2 ;
It was investigated that Liriomyza huidobrensis distributed in broad bean. The resulted showed that spatial distribution patterns of Liriomyza huidobrensis in broad bean is aggregative distribution, the basic component was individual group. The models of the best feasible sampling number of indivdual insect type were gained. The sampling number of eggs N =(6.635?6/ m +0.061?7)/ D 2, The sampling number of larvae N =(0.035?2/ m +0.637?3)/ D 2.According to the spatial distribution and the feasible sampling number, sampling technique in the field was confirmed.
