褐稻虱严重威胁着东南亚、日本、印度次大陆等郊区的水稻生产。在我国南方稻区,褐稻虱也是主要害虫之一。近年来,广大育种和植保工作者紧密协作,在抗褐稻虱育种方面,取得了很大成绩。现根据实践经验谈一点温室饲养褐稻虱和鉴定水稻品种的方法和体会。一鉴定需要大量的2～3龄的褐稻虱若虫。所以,进行水稻品种抗性鉴定的第一步是种好养虫的水稻,养好、养足虫,保证在秧苗二叶一心期时能有龄期较为一致的、数量足够的虫源供鉴。
Brown planthopper is a serious threat to rice production in the suburbs of Southeast Asia, Japan and the Indian subcontinent. In southern China rice area, brown planthopper is also one of the major pests. In recent years, the majority of breeding and plant protection workers work closely together and have achieved great success in the breeding of brown planthopper. Now based on practical experience about a little greenhouses breeding brown rice louse and identification of rice varieties methods and experience. An identification requires a large number of 2 ~ 3 instar brown planthopper nymphs. Therefore, the first step in the identification of resistance to rice varieties is a good kind of supportive paddy rice, keep good, keeping foot worms, seedlings to ensure a second leaf one heart phase can have a more consistent age, adequate number of sources for the Kam .
