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
The biological characteristics of the brown planthopper (Nilaparvata lugens) were studied in nine rice cultivars. The results showed that the effects of different rice varieties on the biological characteristics of BPH were mainly manifested in the survival rate of nymphs and the daily distribution of fecundity and fecundity, but had no significant effect on the developmental rates of nymphs and adult longevity . The biological parameters of different resistant varieties showed inconsistent performance, suggesting that the mechanism of resistance to BPH in rice is very complicated
