| 为明确气候变暖下亚洲玉米螟发生趋势, 连续3年调查了黑龙江省嫩江县亚洲玉米螟越冬代成虫羽化进度和发生高峰期, 同时应用松毛虫赤眼蜂防治嫩江县3个农场玉米田中玉米螟, 结果表明, 2014年亚洲玉米螟成虫出现的高峰期比2012年和2013年有所提前。释放赤眼蜂后玉米植株的被害率、折雄率、残虫率以及钻蛀率较未放蜂田均降低, 玉米产量增加, 防治效果明显。大西江农场、尖山农场和嫩北农场赤眼蜂防治效果分别为60%、66.7%和56.7%, 比未放蜂田产量分别提高39.1、47.6和67.0 kg/667 m2。3个农场平均防治效果为61.1%, 产量平均 提高51.2 kg/667 m2。释放赤眼蜂防治玉米螟对提高玉米产量和品质、挽回经济损失, 保护生态环境具有重要意义。 |

| In order to clarify the new trend of Ostrinia furnacalis under the conditions of climate warming, emergence and peak emergence progress of overwintering adults of O. furnacalis in Nenjiang county of Heilongjiang province were investigated and Trichogramma dendrolimi was released to control O. furnacalis in corn fields in three farms during 2012-2014. The results showed that the peak season of O. furnacalis emergence in 2014 was earlier than that in 2012 and 2013. Compared with those farms without T. dendrolimi releasing, the rate of damage, percentage of tassel broken, residual rate of insect and boring rate were all decreased in the field that released T. dendrolimi, and the yield of corn increased. Control efficacies of T. dendrolimi against O. furnacalis on the Daxijiang farm, the Jianshan farm and the Nenbei farm were 60%, 66.7% and 56.7%, respectively, and the yield increased by 39.1 kg, 47.6 kg and 67.0 kg per 667 m2, respectively, compared with that without T. dendrolimi releasing. The average control efficacy in the whole Nenjiang county was 61.1% and the average yield increased by 51.2 kg/667 m2. Releasing T. dendrolimi is of great significance to control O. furnacalis, increase maize yield and quality, recover economic losses, and protect the ecological environment. |
