| 中文摘要: |
| 为明确杀虫剂对不同世代亚洲玉米螟的防治效果, 设置只防治一代玉米螟, 只防治二代玉米螟, 和一、二代皆防治3个处理, 以一、二代都不防治为对照, 比较不同防治处理下秋季剖秆百株虫孔数、虫口数、被害株率、防治效果和玉米产量。结果表明:不同防治处理的防效间存在显著差异, 3个防治处理的虫孔数、虫口数和被害株数均显著低于对照, 其中一、二代皆防治处理的防效最高, 只防治一代和只防治二代处理的防治效果在年度间存在差异。 |
| 英文摘要: |
| In order to confirm the control effect of pesticide against Asian corn borer (ACB), Ostrinia furnacalis (Guenée) at different generations, the numbers of larvae, stalk cavities per hundred plants, damaged rate, and corn yield were investigated by different treatments in autumn in Jilin Province. The results showed that the control effect of different control treatments had significant difference. The numbers of ACB larvae, stalk cavities per hundred plants, and damaged rate of three control treatments were significantly lower than those of the blank control. Treatment on ACB at both generations had the highest control effect. There were annual differences among the control effect of the treatment only at the first generation or only at the second generation. |
