    摘要:

    为了明确山西省螟黄赤眼蜂对向日葵螟的防治效果、有效控制向日葵螟为害,在满足向日葵螟绿色防控需求方法的同时,针对已有的试验设计方案探讨其合理性、科学性。在山西省闻喜县、曲沃县、夏县开展了螟黄赤眼蜂防治向日葵螟试验,螟黄赤眼蜂防治向日葵螟卵粒寄生率达到81.9%,卵粒校正寄生率达到80.5%,平均防效为70.26%,向日葵平均增产率为22.17%。结果表明农业可持续发展战略下,利用螟黄赤眼蜂生物控制向日葵螟为害,在山西省生态环境下效果明显。

    Abstract:

    In order to clarify the control effect of Trichogramma chilonis on the sunflower moth in Shanxi Province and effectively control the harm of sunflower moth, the rationality and scientificity of the existing experimental design scheme were discussed while meeting the requirements of sunflower moth green prevention and control methods. The experiment was carried out in Wenxi, Qvwu and Xia counties of Shanxi Province. The parasitism rate of eggs and corrected parasitism rate were 81.9% and 80.5%, respectively. The average control effect was 70.26%and the average yield increase rate was 22.17%.
