华南地区中华微刺盲蝽种群动态及迁移规律

Population Dynamics and Migration of Campylomma chinensis Schuh in South China

2002-2003年分别在广州和深圳调查研究了中华微刺盲蝽在胜红蓟、黄槐决明、野茼蒿、肖梵天花和黄皮、芒果、龙眼、荔枝上的种群动态及迁移规律。结果表明,该盲蝽在胜红蓟、黄槐、野茼蒿、肖梵天花上的自然种群数量大,全年共发生1～3个高峰期,高峰期的时间主要集中在3～5月份和11～12月份;中华微刺盲蝽在胜红蓟上的种群密度与蓟马数量存在显著相关性,与蚜虫数量无显著相关性;中华微刺盲蝽成虫在4种果树上分布的时间与果树的花期吻合,且在果园存在明显的迁移规律。因此,在田间中华微刺盲蝽具有较好的保护及利用价值。

Population dynamics and migration ofCampylomma chinensis Sclaula （ttemlptera：Miridae）, a common predatory mirid bug in South China, in fields and orchards were investigated in Guangzhou and Shenzhen from 2002 to 2003. Results indicated that there were 1-3 population peaks of the bugs on the fruit plants, which appeared from March to May and from November to December. Population of C. chinensis was significantly related to that of thrips, however, not obviously to aphis on Ageratum conyzoides. Furthermore, it was showed that the time which the adults of C. chinensis appeared in fruit trees of Dimocarpus longan, Litchi chinensis and Mangiifera indica, Clausena lansium overlapped with the bloom period of the fruit trees. Moreover, the migration of the mirid bug between fruit trees and weeds was regular showed the potential of C. chinensis as a good candidate species in biological control field.
