| 中文摘要: |
| 稻水象甲在浙江双季稻区每年发生２代，以成虫滞育越冬。春季越冬成虫迁入早稻田繁殖，形成１代致害种群；夏季１代成虫生殖滞育，绝大部分个体（９５％以上）迁出早稻田行夏蛰并越冬；秋季２代成虫羽化后，大部分迁飞山上草地越冬。 |
| 英文摘要: |
| Lissorhoptrus oryzophilus Kuschel occurs twice a year in the double cropping paddy rice areas of Zhejiang Province. The imagos stop reproduction and live through the winter. In spring, the overwintered imagos migrate into the early paddy rice fields and begin to reproduce, forming a new and harmful generation. The new generation adults stop reproduction in the summer and most imagos (over 95%) move out of the early paddy rice for aestivation and live through the winter. Most of the scond generation in the autumn also fly into mountainous grassland for overwintering. |
