中华微刺盲蝽对节瓜蓟马的捕食效应

The Functional Response of Campylomma chinesis to Thrips palmi

通过室内试验研究了中华微刺盲蝽 (CampylommachinensisSchuh)对节瓜蓟马若虫的捕食功能反应 ,并通过室内模拟和田间调查研究了微刺盲蝽的空间捕食效应 ,建立了捕食功能反应模型 .结果表明 :微刺盲蝽 4、5龄若虫对节瓜蓟马的功能反应属HollingⅡ型 ,微刺盲蝽成虫对节瓜蓟马若虫的功能反应属HollingⅠ型 ;盲蝽的各个虫态中 ,捕食能力大小顺序为 :成虫 >5龄若虫 >4龄若虫 >低龄若虫 .

The indoor simulation and systematic field investigations were conducted on the density and space functional responses of different stages of Campylomma chinensis Schuh to Thrips palmi Karny. The relationship model among the feeding amount of densities of C. chinensis and densities of T. palmi were developed. It is demonstrated that the functional responses of the forth instar of nymphs and the fifth instar of nymphs to the preys can be described by the type of Holling Ⅱ,while the adult can be described by the type of Holling Ⅰ. In the different stages of C. chinensis from large to small according to their preying efficacies, were adult, fifth instar nymph, forth instar nymph, and low instar nymph. C. chinensis is one of the most potential enemy for controlling Thrips palmi in the south of China.
