巴氏钝绥螨对芦笋上烟蓟马捕食效能研究
Predation Efficacy ofAmblyseius barkeri on Asparagus Thrips, Thrips tabaci
摘要
Abstract
Functional response ofAmblyseius barkeri Hughes to 1st instar nymphs of Thrips tabaci Lindeman and intraspecific interference of the predatory mite were investigated in the lab condition. Results showed that mean daily prey consumption of adult female mite increased with the increase in both temperature and prey densities. With prey densities ranging from 3 to 24 per petri dish, adult female mite predated 2.00--3.75, 2.67--4.75, 2.75-- 5.25, 3.00--11.50 and 3.00--18.33 thrips at 15, 20, 25, 30 and 35℃, respectively,. The predator exhibited a Holling- Ⅱ and Holling-Ⅲ functional response at five constant temperatures. Ovipostional female adult showed the biggest predation capacity; mean daily prey consumption rate of ovipositional female adult, deutonymph, protonymph, male adult mite and post-ovipositional female mite was 3.00--16.00, 1.74--12.92, 1.75--6.93, 2.60--6.25, 2.75--5.00, respectively. There was intraspecific interference in the predatory mite. The predation capacity and predation rate of adult female A. barkeri decreased with the increase of predator densities. Intraspecific interference model at constant ratio of predator to prey or at constant prey densities was E=0.5316P-1＇1177, E= 0.1550P-3614, respectively.关键词
