水稻螟虫是影响我省稻区谷稻增产丰收的一大敌害。近年来,滇中二、三化螟混合发生区,二化螟问题日趋突出,特别是第一代二化螟发生危害较为严重。根据毛主席关于“中国应当对于人类有较大贡献”的教导,为解决在使用农药防治粮食作物病虫害中所出现的残毒等问题;充分挖掘和利用我省的“天敌资源”尽速把我省水稻螟害压到最低限度,保证稻谷更大的增产丰收,结合我们人力、设备等条件,1973年分别在昆明、玉溪、开远三个不同类型地区,对水稻螟虫卵寄生蜂的种类和自然寄生情况,及对稻螟赤眼蜂某些生物学特性和寄主等问题作了一些初步考察。
Rice stem borer is a major enemy of rice production in the rice growing areas of our province. In recent years, the second and third generation of Borer in Yunnan in the mixed occurrence area, the problem of Chilo suppressalis has become increasingly prominent, especially the first generation of Chilo suppressalis is more serious. According to Chairman Mao’s teaching on “China should make greater contribution to human beings”, in order to solve the problem of residues and residues of pesticides used in the prevention and control of crop diseases and pests caused by pesticides, we should make full use of the province’s “natural enemy resources” Rice stem borer damage to a minimum, to ensure a greater yield increase of paddy harvest, combined with our manpower, equipment and other conditions, respectively, in 1973 in Kunming, Yuxi, Kaiyuan three different types of regions, the rice stem borer eggs parasitic wasp species and Natural parasitism, and some biological characteristics of Trichogramma ostriniae and hosts and other issues made some preliminary investigation.
