| 摘 要： | 在实验室条件下,束管食螨瓢虫 Stethorus chengi SaSaji 对桔全爪螨 Panonychuscitri McGregor 高密度区域表现出明显的聚集反应.在猎物密度高的小区停留的时间长于在低密度小区内的时间.该捕食者的个体平均搜索能力和个体平均捕食率与其自身密度成负相关.束管食螨瓢虫对猎物的捕食率与猎物密度相关或成逆密度相关,这种现象可能是由聚集强度和干扰强度所引起的.

| Abstract: | Stethorus chengi SaSaji exhibited a clear aggregative response in laboratory,spending more total time in high prey density paches.There were negative relation between the predator density and average individual searching efficicncy,average individual predatism. Density dependent,density independent and inversely density dependent predatism were mainiy caused by matual interference and aggregation among the predators. |
