| 中文摘要: |
| 本文比较分析了８１６９－２２和丙８８１２２两个水稻品种的抗虱性能。结果表明，二代褐稻虱短翅型、长翅型成虫在丙８８１２２的产卵量只相当于８１６９－２２上产卵量的４５．０２％和４０．９８％；其卵孵化串分别比８１６９－２２上的孵化率低１７．４４％，１９．７６％；短、长翅型成虫处理的若虫存活率分别比８１６９－２２品种低２５．８６％，１８．６１％。大田普查，丙８８１２２品种上的褐稻虱数量比８１６９－２２降低６．３１～１２．３２倍。此品种对褐稻虱表现较好的抗性，在当地一般年份可不予防治。 |
| 英文摘要: |
| The resistence to BPH for rice varieties of 8169-22 and Bing-88122 were studied by com- paring the egg number,percentage of hatching and the nymph’s survival rates of the second generation. The results showed that the egg number by micropterous and macropterous adults on Bing-88122 were 45.02%and 40.98%of that on 8169-22,and the hatching rates were 17.44%and 19.76%lower re- spectively. In addition,the survival rates of the nymphs on Bing-88122 of microptera and macroptera de- creased 25.86%and 18.61%as compared with that on 8169-22. |
