旱作番茄田桃蚜种群空间结构及其抽样技术研究
Study on the Spatial Structure and Sampling Techniques of Myzus persicae Population in Dryland Tomato Fields
摘要
Abstract
To investigate the population occurrence and distribution characteristics of Myzus persicae on tomato fields in cold and dry farming areas in the Hexi region,as well as their monitoring and sampling techniques,the population structure characteristics and sampling techniques of M.persicae populations in tomato fields in Liangzhou District,Wuwei,Gansu Province were studied using random surveys,spatial distribution type tests,and linear regression methods.The results indicated that the occurrence and spatial distribution pattern of M.persicae was clustered in cold and dry farming areas in Liangzhou District.Based on the Iwao regression relationship between mean crowding(M*)and mean density(m),M*=1.836 9 m-1.169 2,the theoretical sampling model for nymphs and adults was established as N=1.962/D2(-0.169 2/m+0.836 9),with a sequential sampling model T(1,2)=5n±8.780 8 n姨.The optimal sampling size based on the estimated control indicators was calculated.关键词
