摘要
通过对棉田动物群落动态及天敌与害虫种群之间关系的系统研究，得出：l）棉田生物多样性指数越大，群落稳定性越高；2）龟纹瓢虫与棉蚜种群数量之间极相关，草间小黑株与棉蚜种群之间有相关关系，棉蚜及龟纹瓢虫种群增长为指数增长；3）棉蚜及其多种天敌在水平分布上均为聚集格局；4）棉蚜、龟纹瓢虫及草间小黑蛛在垂直分布上均为聚集格局，龟纹瓢虫对棉蚜聚集场所具有追随跟踪攻击作用．
According to the systimatic studies on relationship between animal community dy-namics and pest populatlation in cotton field Were shown：l）The higher the index of various kinds of 1iving things in cotton field，the community stability is higher；2）The population of Propylses japonica is closely related to that of Aphis gossypii，the population of Erigonidium graminicola is related to that of A．gossypii；the population growth of A．gossypii and P.japonica are index growth；3）The horizontal spatial distribution patterns of A．gossypii and its nature enemies in amount are of aggregated type；4）The vertical spatial distribution patterns of A．gossypii，P．japonica and E．graminicola in amount are of aggregated type，P．japonica is possesed the action to follow the tracks of A.ossypii and attack it in its aggregated place.
