| 为明确剑毛帕厉螨Stratiolaelaps scimitus对韭菜迟眼蕈蚊Bradysia odoriphaga Yang et Zhang的捕食潜能, 本试验研究了剑毛帕厉螨对韭菜迟眼蕈蚊卵、1龄幼虫和2龄幼虫的捕食功能反应。结果表明:剑毛帕厉螨对不同虫态韭菜迟眼蕈蚊的捕食功能反应都符合Holling Ⅱ型方程, 对3种不同虫态的捕食能力大小为:1龄幼虫＞卵＞2龄幼虫; 对三者的理论日最大捕食量分别为18.76头、16.05粒和2.27头。对韭菜迟眼蕈蚊卵及1、2龄幼虫的寻找效应都随猎物密度的增加而降低; 在0~3 h对卵和1龄幼虫捕食量最大, 捕食速率也最高, 在3~6 h对2龄幼虫的捕食量和速率最高。 |

| To identify the predation potential of Bradysia odoriphaga by Stratiolaelaps scimitus, the functional response of S. scimitus to three stages (egg, first-instar and second-instar larvae) of B. odoriphaga was examined. The results showed that the predation fitted well with HollingⅡtype, and the control ability of S. scimitus to the three stages of B. odoriphaga was: first-instar larva>egg>second-instar larvae; the maximum potential predacious abilities were 18.76, 16.05 and 2.27, respectively, and the searching efficiency decreased with increasing prey density. In 0-3 h, the predation rates for eggs and first-instar larvae were significantly higher than in other times, and that for the second-instar larvae was the highest in 3-6 h. |
