甘蔗绵蚜黄盾蚜小蜂ncarsic flavoscutellum是爪哇甘蔗绵蚜的天敌优势种,该蜂的控制作用是爪哇甘蔗绵蚜发生甚微的主要原因。1926年石田昌人等曾从爪哇引进台湾,历经数年的饲养研究和全台湾岛范围的释放试验,由于环境条件不很适合,防治效果不太理想。1985年11月我们在广东高要和广州近郊发现该种蚜小蜂,局部寄生率高达77％。鉴于20年代台湾作过研究之后,我国大陆未见对该蜂研究的报道,并从初步调查
Nacarsic flavoscutellum is a dominant predatory species of the sugar cane Aphis gossypii. The control effect of this bee is the main reason for the small occurrence of the sugar cane Aphis gossypii. In 1926, Ishihara-chan was introduced into Taiwan from Java. After several years of feeding research and the release test of the entire island of Taiwan, the control effect is not very satisfactory due to the unfavorable environmental conditions. In 1985 November we found in Guangdong Gaoyao and Guangzhou suburbs of the kind of aphids wasps, the local parasitic rate as high as 77%. In view of the research made in Taiwan in the 1920s, there was no report on the study of this bee in Mainland China. From the preliminary investigation
