摘要: 通过田间调查,研究了棉铃虫卵和龟纹瓢虫、中华草蛉空间分布的关系。研究表明,棉铃虫卵和龟纹瓢虫、中华草蛉在棉株垂直各层上的数量间相关系数6月分别为0.5696、0.8620,7月为0.8300、0.9282,8月为0.9083、0.8201,除6月龟纹瓢虫外,其余皆达显着或极显着水平;垂直格局上棉铃虫卵和龟纹瓢虫扩散系数和久野指数间相关系数分别为0.8211、0.7791,皆达极显着水平;水平格局上棉铃虫卵和中华草蛉扩散系数和久野指数间相关系数分别为0.7925、0.5228,分别达极显着和显着水平。

Abstract: Relationships among the spatial distribution patterms of Helicoverpa armigera, and its matural enemies Propylaea japonica and Chrysopa sinica were studied through field investigation. The result showed that the correlation coefficients of quantity in vertical distribution between H. armigera and P. japonica, and H. armigera and C. sinica were 0.5696 and 0.8620 in June,0.8300 and 0.9282 in July,and 0.9083 and 0.8201 in August,with all significant differences except for P. japonica in June. The correlation coefficients of spreading coefficient and Kuno index were 0.8211 and 0.7791 between H. armigera and P. japonica in vertical patterns,and 0.7925 and 0.5228 between H. armigera and C. sinica in horizontal patterns.
