摘要
研究了大灰食蚜蝇对 3种蚜虫的捕食作用 ,得到 1,2 ,3龄幼虫对甘蓝蚜的捕食功能反应模型分别为Na =0 60 82N/ (1+ 0 60 82× 0 1132N) ,Na =0 9810N/ (1+ 0 9810× 0 0 117N) ,Na =0 95 85N/ (1+ 0 95 85×0 0 0 46N) ,日最大捕食量依次为 8 8头、85 4头、2 17 4头 ;3龄幼虫对豌豆蚜虫的捕食功能反应模型为Na =1 1787N/ (1+ 1 1787× 0 0 147N) ,日最大捕食量为 68 0 3头 ;1,2 ,3龄幼虫对桃蚜的捕食功能反应模型为Na=1 0 0 0 5N/ (1+ 1 0 0 0 5× 0 0 95 8N) ,Na =1 10 6 1N/ (1+ 1 10 6 1× 0 0 180N) ,Na =1 0 5 6 6N/ (1+ 1 0 5 6 6× 0 0 0 6 0N) ,日最大捕食量为 10 44头 ,5 5 71头 ,166 67头。结果表明 ,利用大灰食蚜蝇防治蚜虫是具有一定潜力的。
The paper mainly deals with the predation of the aphidophagous syrphid larvae to three aphids. The functional response analysis shows that its predation efficiency is a negative acceleration curve. Holling's (1959) disc equation has been used to describe syrphid predation to aphid.Each model of Surphus corollae Fabricius feeding on Brievicoryne brassicae (Linnaeus) is as follows: 1st instar: Na =0 608?2? N /(1+ 0 608?2 ×0 113?2? N ); 2nd instar: Na =0 981?0? N /(1+0 981?0×0 011?7? N );3rd instar: Na =0 958?5? N /(1+0 958?5×0 004?6? N ).The most consuming rate to Brievicoryne brassicae per day is 8 8, 85 4, 217 4, respectively. The model of the 3rd instar Syrphus corollae Fabricius feeding on soybean aphids ( Megoura japonica and Acyrthosiphon pisum ) is as follows: Na =1 178?7? N /(1+1 178?7×0 014?7? N ).The most consuming rate to soybean aphids per day is 68 03. Each model of Syrphus corollae Fabricius feeding on Myzus persicae (Sulzer) is as follows: 1st instar: Na =1 000?5? N /(1+1 000?5×0 095?8? N ); 2nd instar: Na =1 106?1? N /(1+1 106?1×0 0179?5? N );3rd instar: Na =1 056?6? N /(1+1 056?6×0 006?0? N ).The most consuming rate to Myzus persicae per day is 10 44,55 71,166,57, respectively. The experemental result shows it is potential to use Surphus corollae to control lots of aphid specieses.
