摘　　要：松突圆蚧花角蚜小蜂Coccobius azumai Tachikawa是有效防治松突圆蚧Hemiberlesia pitysophilaTakagi的重要寄生性天敌。在前人对花角蚜小蜂研究的基础上,2002年5月从日本冲绳引进松突圆蚧花角蚜小蜂后,改进了人工大量收蜂技术,应用自行设计的收蜂棚进行敞口式大量收蜂,大大提高了收蜂量。2006—2007年分别收到花角蚜小蜂22 372头和54556头。在福建松突圆蚧发生区推广应用,为松突圆蚧的生物防治提供了行之有效的持续控制措施。Coccobius azumai Tachikawa was a natural enemy parasitizing Hemiberlesia pitysophila. Based on the previous studies, artificial recapture techniques of Coccobius azumai were improved. Selfdesigned open sheds were used for mass collection of C. azumai to increase the recapture amount. The result showed that large number of C. azumai could be recaptured. A total of 22 372 and 54 556 C. azumai was recaptured respectively in 2006 and 2007. In addition, the technique was popularized and applied in Fuqing, Changle, Minhou, Quanzhou and Hanjiang to provide sustainable control measures for the biocontrol of H. pitysophila.
