林业部组织的中国松树害虫考察团王淑英、潘务耀、黄邦侃等于1986年7月15~29日,在日本冲绳进行了松突圆蚧的考察,对寄生性天敌进行了调查、分析,认为日本冲绳琉球松历年发生松突圆蚧,均未发现被害状,虫口密度在1.45~2.86头/束,平均2.10头/米。发现寄生性天敌有明显的优势种,经有关专家鉴定,确认为花角蚜小蜂(Coccobius sp.)种名待定。其寄生效能高,主要寄生松针叶鞘的雌蚧虫,占总寄生的82.5%。广东省林业厅森防站,在日本琉球大学东清二教授的协助下,相继采样邮寄或携带八批材料,在惠东寨场山试验点进行了分析试验。其中,于1987年10月7~13日
The Chinese pine pest delegation organized by the Ministry of Forestry Wang Shuying, Pan Yuanyao, Huang Bangkan et al. Were investigated in Okinawa, Japan on July 15-29, 1986 and investigated and analyzed the parasitic natural enemies. They believed that Japan Okinawa Ryukyu Pine cedutemon occurred over the years, none of the victims were found. The population density was 1.45-2.86 heads / bundle with an average of 2.10 heads / meter. Parasitic natural enemies were found to have obvious dominant species, identified by the relevant experts, confirmed as Coccobius sp. (Coccobius sp.) Species to be determined. The parasitic efficiency of the main parasitic pine needles sheath female scale insects, accounting for 82.5% of the total parasitism. With the assistance of Professor Dong Qing-II of Ryukyu University in Japan, Forest Department of Guangdong Provincial Forest Prevention Station sampled and sent eight batches of materials in succession and carried out analytical tests at the Huidong Zhaichang Mountain Experimental Station. Among them, in 1987 October 7 ~ 13
