作者于1986年8月至1987年7月期间:对南宁芒果扁喙叶蝉(Idiocerus incertus(Baker))春夏秋季种群的空间分布进行了研究,按照Iwao方法和Taylor方法,应用M~*=α+βM和V=aM~b拟合原始数据,测定其分布型为聚集分布.分析了种群的聚集特征和原因,并应用分布型参数拟定了理论抽样数.本文提供的各项参数为该虫春、夏、秋季种群的防治、抽样调查和野外资料分析提供必需的生态学依据.
The author studied the spatial distribution of population of Idiocerus incertus (Baker) in spring, summer and autumn in Nanning from August 1986 to July 1987. According to Iwao method and Taylor method, M ~ * = α + βM and V = aM ~ b were fitted to the original data, the distribution was determined as the aggregation distribution.The characteristics and causes of the population aggregation were analyzed, and the theoretical sampling number was formulated using the distribution parameters.The parameters provided in this paper are Insect spring, summer and autumn population control, sampling and field data analysis provides the necessary ecological basis.
