中文摘要:
      玉米螟赤眼蜂是生物防治中一种重要的天敌昆虫,为探明艾叶精油对玉米螟赤眼蜂的影响及两者对米蛾的联合防治效果,本文研究了艾叶精油熏蒸、触杀、驱避活性对玉米螟赤眼蜂的影响及艾叶精油和玉米螟赤眼蜂对米蛾的联合作用。结果表明,艾叶精油熏蒸和触杀处理对玉米螟赤眼蜂卵具有明显影响,寄生在米蛾卵上的玉米螟赤眼蜂卵经0.1、0.2、0.3、0.4、0.5、0.6μg/cm3艾叶精油熏蒸处理72 h后玉米螟赤眼蜂的羽化率分别为56.67%、49.33%、44.00%、33.33%、26.00%和14.67%;寄生在米蛾卵上的玉米螟赤眼蜂卵经100、200、300、400、500、600 mg/L艾叶精油触杀处理72 h后玉米螟赤眼蜂的羽化率分别为54.00%、45.33%、38.00%、28.67%、18.00%和6.00%,均与对照组表现出显著性差异。艾叶精油驱避活性对玉米螟赤眼蜂成蜂也有明显的影响,300 mg/L艾叶精油对玉米螟赤眼蜂的驱避率79.05%,随着时间间隔和距离间隔的增加,这种影响作用降低;联合应用艾叶精油与玉米螟赤眼蜂时先释放玉米螟赤眼蜂,24 h后再滴加艾叶精油的防治效果最佳,米蛾的死亡率可高达96%。
英文摘要:
      Trichogramma ostriniae is an important natural enemy in biological control.In order to find out the effect of Artemisia argyiessential oil on T.ostriniaeand their combined effect on the control of Corcyra cephalonica,the fumigation, contact and repellent activities of A.argyiessential oil on T.ostriniae were studied, as well as the combined action of A.argyiessential oil and T.ostriniae on the C.cephalonica. The results showed that the A.argyi essential oil had good fumigation and contact activities on T.ostriniae.The emergence ratios of T.ostriniae which parasitized in the C.cephalonica eggs were 56.67%, 49.33%, 39.33%, 33.33%, 26.00% and 14.67% respectively, after 72 h fumigation with 0.1,0.2,0.3,0.4,0.5,0.6 μg/cm3 A.argyi essential oil, and the emergence ratios after 72 h contacting treatment with 100, 200, 300, 400, 500, 600 mg/L A.argyi essential oil were 58.00%, 45.33%, 38.00%, 28.67%, 18.00% and 6.00%, all the results showed significant difference (at 5% level) to the control.The emergence rate of T.ostriniaedecreased with the increase of the concentration of essential oil.At concentration of 300 mg/L the A.argyiessential oil displayed 79.05% repellent ratio on T.ostriniae, and the repellent activity decreased while the distance and time interval of the essential oil treatment were added.As for the combined effect of both A.argyiessential oil and T.ostriniae, the best treatment was applying T.ostriniaefirstly and 24 hour later A.argyiessential oil, which could get 96% C.cephalonica mortality.
