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 .中华微刺盲蝽是我国南方控制瓜类和茄类害虫节瓜蓟马最有潜力的天敌之一
The predation-functional response of Campylommachinensis Schuh to N. nirvana was studied by laboratory experiments and the predation-eating effect was studied by laboratory simulation and field investigation, and a predator-prey functional response model was established. Results The results showed that the functional response of the 4th and 4th instar nymphs of Brachypteris occidentalis to Hollysia nodorum was Holling Ⅱ. The functional response of the adult Lygus nucifera to Holly nylons was Holling Ⅰ. The order of their abilities is as follows: adults> nymphs of the fifth instar> nymphs of the fourth instar> nymphs of the younger nymphs. The Chinese stink bug is one of the most potential natural enemies to control melons and thrips in southern China.
