【摘要】 研究了褐飞虱的生物学特性在 9个水稻品种上的变化。结果显示 ,不同水稻品种对褐飞虱生物学特性的影响主要表现在若虫期的存活率和成虫期的产卵量及产卵量的日分布规律上 ,对若虫的发育速率和成虫的寿命影响不明显。各生物学参数在不同抗性品种上的表现不一致 ,说明水稻的抗褐飞虱机制是非常复杂的更多还原

【Abstract】 Experiments have been caried out to study the effects of different rice varieties on the biological properties of brown plant hopper(BPH).The results indicated that rice variety mainly affects the nymph′s survival rate and the adult oviposition.No significant difference was observed in nymph′s development and adult longevity when BPH was reared on the tested nine different varieties.The biological parameters of BPH population always change with rice varieties,so it is considered that the resistance of rice variety to BPH is very complicated.更多还原
