| 摘 要： | 介绍了节瓜蓟马在广东省的捕食性天敌资源和自然控制作用。在不施化学农药的瓜、豆地中发现节瓜蓟马的捕食性天敌有中华微刺盲蝽、黑带多盲蝽、黑肩绿盲蝽、南方小花蝽、桑小花蝽、大眼长蝽、西方蠳蚊、长毛捕食螨、塔六点蓟马、瓢虫、蜘蛛和蚂蚁等共10科近20种。数量较多的是中华微刺盲蝽、南方小花蝽和黑带多盲蝽,其中对节瓜蓟马起主要控制作用的是中华微刺盲蝽。在所有被捕食的节瓜蓟马中,54%的蓟马被中华微刺盲蝽取食。中华微刺盲蝽不仅捕食量大,而且全年可见该盲蝽繁殖。中华微刺盲蝽是防治节瓜蓟马前景最大的天敌之一。

| Abstract: | Predatory arthropods of Thrips palmi (Karny) were surveyed from the spring of 2001 through to the spring of 2002 in non-sprayed vegetable crops in Guangdong province. The predatory fauna comprised arthropods in 10 families. The anthocorid bugs Orius.Similis Zheng and the mirid bugs Campylomma chinensis Schuh and Dortus chinai Miyamoto were the most numerous and widely distributed species observed, constituting 95% of all predators. these indigenous predators, C. chinensis is most likely to be effective against Thrips palmi.54 % Thrips palmi that were preyed by predators were preyed by C. chinensis. C. chinensis can reproduce all around a year. C. chinensis is one of the most potential enemies of controlling thrips palmi in Southern China. The potential of the main 3 species for biological control of Thrips palmiis is discussed. |
