红铃虫卵田间分布的研究曾有报导,但是作者提出的理论抽样数和均数之间的关系。与我们的实践有很大距离。为此,我们在1981—1983年进行了调查研究。一、材料的获得八一年二、三代红铃虫发生期间,根据病虫测报的传统办法,成片连续调查,每个单株随机抽查一个成铃上的卵量,先后调查了七块田,计9309个单株,平均单铃卵量0.16—0.67 Research on the distribution of red bollworm eggs in the field has been reported, but the authors suggest the relationship between the number of theoretical samples and the mean. There is a great distance from our practice. To this end, we conducted a survey in 1981-1983. First, the material obtained 81 years two or three generations of pink bollworm occurred during the period, according to the traditional method of pest forecasting, into a piece of continuous investigation, each single random sampling of a bell on the amount of eggs, has investigated seven fields , Counted 9309 single plants, the average number of single bell eggs 0.16-0.67
