| 摘 要： | 烟粉虱Bemisiatabaci(Gennadius)]在花卉一品红上的为害十分猖獗,在调查分析的基础上,研究了烟粉虱在一品红上的序贯抽样技术。结果表明:烟粉虱成虫的平均拥挤度*m与平均密度x-回归方程为*m=-9.05+2.26x-,相关性极显著(0.799 1);以Iwao的序贯抽样为基础,结合Kuno的序贯抽样,提出复序贯抽样技术,防治指标上下限为T′0(n)=7n+2 5.39n,T″0(n)=7n-2 5.39n,截止线为T(n)=α+1/(D02-β-1/n),D0=0.15。

| Abstract: | The results showed that the regression equation of mean crowding(m) and mean density(x) of Bemisia tabaci was m=-9.05+2.26x,with a very high correlation coefficient.On the basis of the Iwao's sequential sampling technique and combined with the Kuno's sequential sampling technique,the complex sequential sampling was put forward.The upper limit,lower limit and close string were T′0(n)=7n+2 5.39n,T″0(n)=7n-2 5.39n,andT(n)=α+1/(D02-β-1/n),D0=0.15。(t=2,D0=0.15) for the target pest,respectively.The largest number of specimen was 18. |
