Insect distribution type is one of the population attributes, which is of significance either in theoretical ecology or in pest forecast and control. Wheat stem maggot ( Meromyza Sultatrix Linne) is the main pest of spring wheat in the west of Inner Mongolia. This pest reduced spring wheat production by one hundred million kg. in this region in 1978. We made an investgation and analysis on the field distribution types of wheat stem maggot ova in six plots of three different places in 1980-1981. The results...

Insect distribution type is one of the population attributes, which is of significance either in theoretical ecology or in pest forecast and control. Wheat stem maggot ( Meromyza Sultatrix Linne) is the main pest of spring wheat in the west of Inner Mongolia. This pest reduced spring wheat production by one hundred million kg. in this region in 1978. We made an investgation and analysis on the field distribution types of wheat stem maggot ova in six plots of three different places in 1980-1981. The results are follows:1 . Wheat stem maggot ova and oval stems were both of gathering distribution in the field and accorded with the negative binoial distribution.The results of M-Mregression analysis are α= 0. 4633 > 0 and β=1.081>1.2 . By testing the normal independence we found the data of the oal stems are: log( x + 1/2) and log( x + k/2 ) .3 . By calculating the number of oval stems to determine the control standard, the question of sequential sampling was used: d1= 0.3895n-4.55 and d2=0. 3895n+4. 55

昆虫的分布型是种群的属性之一,无论在理论生态、虫情预测还是害虫科学治理中,都有十分重要的意义.麦秆蝇(Meromyza saltatrix Linne)是内蒙古自治区西部春小麦的主要害虫,1978年大发生时曾造成全区小麦减产1亿公斤.经1980—1981年对三个点六块田麦秆蝇卵田间分布型的调查研究与分析,其结果是:(1)麦秆蝇卵与小麦着麦秆卵茎(下简称小麦着卵茎)在田间均为聚集分布,并符合负二项分布.经M—M回归分析α=O.4633>0,β=1.081>1.(2)经正态独立性检验.小麦着卵茎的资料代换公式为:log(x+1/2),log(x+k/2).(3)田间调查小麦着卵茎,确定是否需要防治的序贯抽样方程为:a_1=0.3895N-0.455,d_2=0.3895N+5.

This paper introduces the important ideas and methods of theoretical ecology anddiscusses how to increase the life of large-middle businesses from the business strategies in our coun-try.
