    EVALUATON RESISTANCE OF NEW RICE LINES HONG-YUAN AND TAINUO XUAN TO THE BROWN PLANTHOPPER,Nilaparvata lugens

    • 摘要: 应用分泌蜜露量,种群趋势指数,内禀控制率,群体建立和田间控制率等指标,综合评价新品系红源和台糯选对褐稻虱的抗性。结果表明:(1)饲养在红源和台糯选上褐稻虱的成虫体重,分泌蜜露量,产卵量和若虫存活率均比在感品种TN1的低,表明品系对褐稻虱具有强抗性作用:(2)飞虱在TN1上的种群趋势指数为247.7,台糯选为38.2,红源为38.4,而抗虫品种Mudgo为10.6;(3)台糯选,红源和Mudgo的内
