根据1986～1988年在泸州调查的资料,采用频次分布检验和聚集强度指标判定法,对粟穗螟幼虫田间种群空间分布型进行了探讨。结果表明,高梁粟穗螟种群的空间分布不受虫口密度和时间的影响,均属聚集分布。分布的基本成分为个体群。聚集强度随虫口密度的升高而增大。
According to the survey data from 1986 to 1988 in Luzhou, the spatial distribution patterns of the spider mites were studied using frequency distribution test and aggregation intensity index determination method. The results showed that the spatial distribution of the population of S. miller was independent of population density and time, and all belonged to the aggregation distribution. The basic components of the distribution of individual groups. Aggregation intensity increased with the increase of insect population density.
