- 摘要:
- 为筛选最佳蜂种,提高赤眼蜂的防治效果,采用玉米螟赤眼蜂、螟黄赤眼蜂、松毛虫赤眼蜂在玉米田放蜂4次,并通过玉米螟的卵块寄生率、玉米植株各个部位危害程度和产量损失评估指标进行比较,来研究不同种类赤眼蜂防治玉米螟的效果。结果表明:玉米螟赤眼蜂的寄生率最高达92.1%,松毛虫赤眼蜂为65.2%,螟黄赤眼蜂为56.3%。综合各项指标得出最佳防治蜂种为松毛虫赤眼蜂,4次放蜂可有效提高赤眼蜂防治效果。
- Abstract:
- In order to screen the best bee species,improve the control effect of Trichogramma,Trichogramma ostriniae,Trichogramma chilonis and Trichogramma dendrolimi were used to control maize borer in maize field for 4 times,through comparing the parasitism rates of various types of Trichogramma on Asian maize borer egg and the injury extent of maize borer on plant parts in fall,yield loss assessment,the optimal control method were researched to improve the control effect of Trichogramma.The results showed that the parasitic rate of Trichogramma ostriniae up to 92.1%,Trichogramma dendrolimi reached 65.2%,Trichogramma chilonis reached 56.3%.Comprehensive results indicated that the best control of bee species for Trichogramma dendrolimi,four times putting bees could effectively improve the control effect of Trichogramma.
