基于自然寄主的黑肩绿盲蝽大规模饲养技术

Mass Rearing of Cyrtorhinus lividipennis(Reuter)on Natural Hosts

黑肩绿盲蝽Cyrtorhinus lividipennis(Reuter)是稻飞虱的重要捕食性天敌。研发黑肩绿盲蝽人工饲养技术对开展稻飞虱绿色可持续防控及其生物学基础研究具有重要作用。本研究采用水稻幼苗作为产卵寄主、以自然寄主褐飞虱作为猎物,从饲养器具、饲养流程及方法等方面建立了一套简便实用的黑肩绿盲蝽规模化饲养技术。利用该技术可连续饲养并提供龄期整齐的黑肩绿盲蝽成虫;经过6个月饲养,发现10 m2房间可日产黑肩绿盲蝽成虫1000~1600头。该饲养技术适合黑肩绿盲蝽的长期规模化饲养,同时也为其他捕食性天敌昆虫规模化饲养提供参考。

Cyrtorhinus lividipennis is one of the most important predatory natural enemies of rice planthoppers in Asia.Developing an efficient rearing procedure for this natural enemy is important to the green and sustainable management of planthoppers and basic research of the predator.A simple yet practical mass rearing procedure for the predator was established,with young rice seedlings as oviposition hosts and natural host brown planthoppers as prey.The rearing kits,procedure and methods were detailed.The mass rearing procedure can continuously produce cohorts of C.lividipennis adults.In a 6-month period,cohorts of C.lividipennis adults of 1000—1600 per day were produced from a 10-square meter rearing room.The developed procedure is suitable for long-term mass rearing of C.lividipennis and can serve as a reference for the mass rearing of other predatory natural enemies.
