【摘要】 褐尾库蚊(Culexfuscanus Wiedemann)幼虫捕食行为的研究结果表明:单个饲养的褐尾库蚊4龄幼虫的日捕食量随白纹伊蚊密度的提高而增大,随自身密度的提高而减小;褐尾库蚊4龄幼虫喜食白纹伊蚊4龄幼虫,对蛹的捕食量远远低于幼虫.猎物的大小、密度和活动能力影响了褐尾库蚊幼虫对猎物的选择性.更多还原

【Abstract】 The predatory behavior of the larvae of Culex fuscanus Wiedemann was studie d. The results were as follows: the predatory quantity of 4th instar lar vae of C.fu scanus Wiedemann decreased with the increase of their density, and increased wi th the increase of the density of Aedes albopictus; the 4th instar larvae of C.fuscanus Wiedemann prefered the 4th instar larv ae of A.albopictus to C.quinquefasciatus for eating, and the predatory quantity of larvae of mosquitoes was more than pupae. The size, density and mobility of quarry affected the selection of larvae of C.fuscanus Wiedemann for quarry.更多还原
