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，其余皆达显著或极显著水平；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 ，皆达极显著水平；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 ，分别达极显著和显著水平．
Through the field investigation, the relationship between the cotton bollworm eggs and the ladybug and ladybugs was studied. The results showed that the correlation coefficients between cotton bollworm eggs, Propylaeia japonica and Scirpus lachrymata in the vertical layers of cotton plants were 0 in June respectively. 5696, 0. 8620, July is 0. 8300, 0. 9282, August is 0. 9083, 0. 8201, except for Propylaea japonica, all reached significant or extremely significant levels in June. The correlation coefficients between the diffusion coefficient of Helicoverpa armigera and Primula longicornis were 0 in vertical pattern. 8211, 0. 7791, reached the extremely significant level. The correlation coefficient between the diffusion coefficient of Helicoverpa armigera and Chinese wild grass was 0 in the horizontal pattern. 7925, 0. 5228, respectively, reached an extremely significant and significant level.
