摘  要:
测定龟纹瓢虫Propylaeajaponica (Thunberg)捕食棉蚜Aphisgossypii (Glover)的功能反应和寻找效应。结果表明 ,其捕食量随猎物的密度增加而上升 ,当猎物增加到一定水平 ,捕食量趋向稳定。拟合捕食功能反应曲线 ,符合Holling功能反应Ⅱ型 ,其模型为 :Na =1 1837N/ 1+0 0 0 5 9N。日最大捕食量为 2 2 6头。龟纹瓢虫寻找效应随自身密度增加而降低 ,模型为 :E =0 5 981×P-1 70 81。干扰反应模型为 :E =0 9733×P-2 0 76。 3个模型为正确评价龟纹瓢虫控制棉蚜的作用提供了科学依据

摘  要:
The experiment results show that the functional response models that Propylaea japonica preyed on Aphis gossypii are as follows: Na=1 1837N/(1+0 0059N).Relationship bitween amount of aphid preyed by ladybird and density show a negative accelerative curre.The daily maximum number of aphid preyed the oretically by ladybirds is 226.The searching efficiency decreases with increase of predator density,and the mathematical models are :E=0 5981×P -1 7081 .The nutural interference among individual predators and preys can described by Hassell (1969) equation:E=0 9733×P -2 0760 .The above three models provide the scientific basis for controlling cotton aphid used Propylaea japonica .
