摘要: 根据目前吉林省亚洲玉米螟新的发生为害情况,为提高防治效果,于2018—2020年在吉林省进行了松毛虫赤眼蜂防治亚洲玉米螟田间放蜂方法优化试验。田间试验结果显示,不同的放蜂处理间防治效果存在显著性差异,增加放蜂次数和放蜂量均能提高防治效果,且利用松毛虫赤眼蜂防治,连续防治一代和二代亚洲玉米螟防治效果最佳,防治效果可达到79.32%。建议防治一代亚洲玉米螟时,每667 m2释放15000头蜂,分3次释放,第1次3000头,第2次7000头,第3次5000头,每次放蜂每667 m2设2个放蜂点;防治二代亚洲玉米螟时,每667 m2释放10000头蜂,放1次,分2个点放蜂;同时,利用植保无人机释放松毛虫赤眼蜂防治亚洲玉米螟1334 hm2,防治效果达到76.36%~81.23%。

Abstract: To improve the control of Ostrinia furnacalis showing new situation of occurrence and damage in Jilin Province, we conducted tests for optimal field release methods for Trichogramma dendrolimi from 2018 to 2020. The field tests showed significant differences in the control afforded by the Trichogramma released by different methods. Either increasing the number or the amount of Trichogramma release improved the control efficiency. When T. dendrolimi was used continuously to control the first and second generations of O. furnacalis, the control efficiency reached the highest of 79.32%. It is recommended that for control of the first generation of O. furnacalis, 15000 T. dendrolimi wasps be released in three times at quota of 3000, 7000, and 5000 wasps, respectively, at 2 release points each time per 667 m2. For the second generation of O. furnacalis, 10000 T. dendrolimi wasps are released once at 2 release points per 667 m2. In our practice, T. dendrolimi was released by plant protection UAV in an area of 1334 hm2 for control of O. furnacalis, the control efficiency reached 76.36%―81.23%.
