【摘要】 对田间褐飞虱主害代的混合种群进行了致害性的测定。结果表明,2008年田间褐飞虱致害类型发生了较大变化,由原来以生物Ⅰ、Ⅱ型混合发生向强致害性的生物Ⅲ型转变,且生物Ⅲ型个体所占比例较高。
【Abstract】 In this paper,the biotypes of brown planthopper were determined by population and individuals.The results showed that the biotypes in the fields turned into Biotype 3 from Biotype 1 and 2,and we should pay high attention to the increasing of Biotype 3 for its strong destructivity.
