| 本文在25±1℃、相对湿度80%±5%和光照(L∶D=16 h∶8 h)条件下研究了黄瓜新小绥螨 Neoseiulus cucumeris 对二斑叶螨 Tetranychus urticae 不同螨态的捕食功能反应、捕食选择性及个体间干扰反应，以期为黄瓜新小绥螨的大田释放和利用提供理论依据。结果表明，黄瓜新小绥螨对二斑叶螨各螨态捕食功能反应符合Holling Ⅱ型圆盘方程，其对二斑叶螨卵( a/Th=47.9965)的控制作用强于若螨(a/Th=27.6906)和成螨(a/Th=9.3963)。黄瓜新小绥螨对二斑叶螨卵和若螨表现为正喜好性(Ci＞0)、成螨表现为负喜好性(Ci＜0)。在相同猎物密度下，黄瓜新小绥螨对二斑叶螨成螨捕食率随着自身密度增大而降低，捕食者自身密度干扰反应方程为E=0.2225P-0.617。 |
| 英文摘要: |
| In order to clarify the predatory functional response, predatory selectivity and individual interference response of Neoseiulus cucumeris to different stages of Tetranychus urticae under the lab condition of 25±1℃, RH 80%±5%, and light(L∶D=16 h∶8 h). The result showed that the predatory response of N.cucumeris to T. urticae was in accordance with the HollingⅡdisc equation, among which, the control effect on the eggs (a/Th =47.9965)was the strongest, than that of the nymphs (a/Th =27.6906 )and adults ( a/Th =9.3963)followed respectively N. cucumeris showed positive preference to T. urticae eggs and nymphs ( Ci >0), and showed negative preference to adults (Ci <0). At the same prey density, the predation rate of N. cucumeris on the adults of T. urticae decreased with the increase of its own density, and the predator's own density interference response equation was E=0.2225P -0.617, which will further provide theoretical basis for the field release of N. cucumeris. |
