70年代中期以来,籼型杂交水稻在全国范围内先后大面积推广,对粮食的增产,已经发挥了巨大的经济效益。 作为杂交水稻主要害虫之一的螟虫,各地普遍开展了稻螟的生物学特性、种群结构等的研究,现就我们的调查研究及部分省、自治区的有关资料,综合报道如下。 Since the mid-1970s, indica hybrid rice has been widely popularized throughout the country, and has exerted tremendous economic benefits on the increase of grain output. As one of the major pests of hybrid rice stem borers, the biological characteristics of the borer are generally carried out throughout the study of population structure, etc. Now on our investigation and research and some provinces, autonomous regions, the relevant information is as follows.
