采用聚集指标法,Iwaom-x直线回归法和Taylor指数法对玉米田四代棉铃虫幼虫种群的空间分布型进行了测定。结果表明玉米田四代棉铃虫幼虫种群呈均匀分布,种群个体间相互排斥。
The spatial distribution patterns of four generations of cotton bollworm larvae in maize field were determined by using aggregation index method, Iwaom-x linear regression method and Taylor index method. The results showed that the four generations of cotton bollworm larvae were evenly distributed in the corn field, and the individuals of the population were mutually exclusive.
