| 胡瓜钝绥螨Amblyseius cucumeris Oudemans能捕食为害蝴蝶兰的害螨---太平洋细须螨Tenuipalpus pacificus Baker的卵、幼螨、若螨和成螨。室内研究了胡瓜钝绥螨雌成螨对太平洋细须螨卵、幼螨、若螨的捕食功能反应。结果表明，随着太平洋细须螨密度的增加，胡瓜钝绥螨雌成螨对太平洋细须螨的捕食数量也随之上升，捕食功能反应曲线符合Holling II型方程。胡瓜钝绥螨雌成螨对太平洋细须螨卵的控制能力显著强于对幼螨和若螨的控制能力，a/Th值分别为165.8、79.2和63.8。在猎物密度一定时，由于胡瓜钝绥螨个体间存在相互竞争和相互干扰作用，随着捕食螨密度的提高，捕食螨平均捕食量逐渐减少。 |
| 英文摘要: |
| Tenuipalpus pacificus Baker is a pest damaging the Phalaenopsis orchid. Amblyseius cucumeris Oudemans can prey all stages of T. pacificus. The predatory function response of A. cucumeris female adult to T. pacificus was studied in the laboratory. The result showed that the predation number of A. cucumeris to T. pacificus increased with the density of T. pacificus increase until it went to steady and the functional response belonged to Holling II model. The control ability of A. cucumeris to egg of T. pacificus was significantly better than that of A. cucumeris to the other stages of T. pacificus. The values of a/ Th are 165.8, 79.2 and 63.8 respectively. Due to mutual competition and interference, consumption rate per predator decreased with increasing predator density. |
