褐稻虱是我省的主要水稻害虫之一,在防治上,仍以药剂防治为主。“事物都是一分为二的。”药剂防治见效快,使用方便,但是长期连续施用农药,带来诸如残毒、环境污染、害虫抗药性、杀伤大量天敌和提高成本等问题。为了解决这些问题,贯彻“预防为主,综合防治”的植保方针,必须寻求其他有效的防治途径。为此,近年来我们征集了一些国内外水稻品种,进行对褐稻虱抗性的鉴定。供鉴定的水稻品种,国外以印度系统的秈稻为主,国内以群众反映田间虫量较少的品种为主。现将鉴定结果简报如下:
Brown planthopper is one of the main rice pests in our province. In the prevention and control, it is still dominated by chemical control. “Everything is divided into two.” Pharmacy is quick and easy to use, but long-term continuous application of pesticides poses problems such as residual poisoning, environmental pollution, pest resistance, killing a large number of natural enemies and raising costs. In order to solve these problems and implement the plant protection principle of “prevention first and comprehensive prevention and control”, we must seek other effective prevention and control measures. To this end, in recent years, we solicit some domestic and foreign rice varieties for identification of brown planthopper resistance. For the identification of rice varieties, the Indian system of Indica-based abroad, the domestic population to reflect the population less insect species mainly. Now the results of the briefing is as follows:
