在人工气候室内黑肩绿盲蝽Cyrtorhinous lividipennis(Reuter)褐对飞虱Nilaparvata lugens Stal高密度小区表现出明显的聚集反应。在褐飞虱密度高的小区出现的时间大于在低密度小区内的时间。其聚集的机制很可能是该捕食者对高猎物密度小区的捕食频繁,停留的时间也更长。尽管黑肩绿盲蝽表现出很明显的聚集行为,但是它们对褐飞虱的捕食率却与褐飞虱的密度无关或成逆密度相关。形成这种现象的据本原因是捕食者的最大食量和该捕食者在各害虫密度小区内的搜索时间限制。
Cyrtorhinous lividipennis (Reuter), a black-shouldered planthopper, showed a significant aggregation response to the Nilaparvata lugens Stal high-density plot in the plantation. The time of emergence in a cell with a high density of brown planthopper is greater than that in a low density cell. The mechanism of its aggregation is likely to be that the predator prey on high densities of densely populated areas and spend longer periods of time. Although Apodemus accumbens showed a very significant aggregation behavior, their predation rates on BPH were not related to or were inversely related to the density of BPH. The reason for the formation of this phenomenon is the predator’s maximum food intake and the search time limit of the predator in each pest density cell.
