| 中文摘要: |
| 应用二化螟性诱剂对越冬代二化螟雄蛾进行了大面积诱捕。结果表明：诱杀７ｄ和１５ｄ后，诱捕区（包括中心区和边缘带）雄蛾量分别为对照区的４０.４４％和２９.７８％，其中心区的蛾量分别为边缘带的４８.５５％和２４.６５％；诱捕区卵块数仅为对照区的２０.０％～３３.３％，枯鞘率仅为对照区的１２.５％～２５.０％；诱捕区的第一代雄蛾发生量大量减少，诱蛾量仅为对照区的４６.９６％，其中心区的雄蛾量为边缘带的６７.６４％；诱捕区的水稻枯心率仅为对照区的３９.５０％～４４.７５％。应用性诱剂大面积诱捕是防治水稻二化螟的有效方法之一。 |
| 英文摘要: |
| The male moth of overwinter generation of rice stalk borer Chilo suppressalis Walker was trapped by sex pheromones on a large scale. Seven and fifteen days affer application, the results for the two dates showed that the moth numbers in trapping areas were 4044% and 2978% of that in control areas, and in treatment areas, the moth numbers in centre parts were 4855% and 2465% of that in edge belts, respectively. The egg mass numbers and the wilt sheath shoot rates in treatment areas were 200%-333% and 125%-250% of that in control areas, respectively. The proportions of wilt heart shoot in trapping areas were 3950%-4475% of that in the control areas. |
