一、甘蔗田赤眼蜂的自然种群及其优势种调查广东省研究利用赤眼蜂防治甘蔗螟虫,始于五十年代。在生产上应用已有多年历史。近十多年来,由于国内、外赤眼蜂种类调查和分类研究的发展,国内对玉米田和稻田赤眼蜂种类的调查及优势种的找寻和应用,对进一步研究和提高赤眼蜂的繁殖和利用,稳定田间效果,起着重要的作用。为了弄清甘蔗田赤眼蜂种类,了解其优势种群,为今后甘蔗田利用赤眼蜂防治甘蔗螟虫提供理论根据,从1980年开始到1982年,我们在
First, the natural population of sugarcane Trichogramma and its dominant species survey Guangdong Province, the use of Trichogramma to control sugarcane borers, began in the fifties. It has been used in production for many years. In the recent ten years, due to the development of the investigation and classification research on the species of Trichogramma at home and abroad, the domestic investigation on the species of Trichogramma species in maize field and paddy field and the search and application of dominant species, Breeding and utilization, stabilizing the field effect, plays an important role. In order to understand the species of Trichogramma in sugarcane field and understand the dominant species, we can provide the theoretical basis for the future use of trichogramma in the control of sugarcane borer in sugarcane field. From 1980 to 1982,
