摘  要:
通过室内试验测定了1种寄主植物烟草和2种非寄主植物滇杨、桉树叶的不同溶剂(石油醚、氯仿和乙醇)提取物,在0~72 h对马铃薯块茎蛾的产卵抑制效果。结果表明,3种植物中均含有抑制马铃薯块茎蛾产卵的化学物质。烟草的石油醚提取物对雌虫无产卵抑制活性,乙醇提取物在0~24 h表现出显著的产卵抑制活性,而氯仿提取物的产卵抑制活性可持续48 h。滇杨叶的3种溶剂提取物均对马铃薯块茎蛾雌蛾表现出显著的抑制效果,但石油醚提取物的作用时间仅为24 h,而氯仿与乙醇提取物的作用时间可达48 h。桉树叶的3种溶剂提取物均在24 h内对雌蛾表现出显著的产卵抑制效果,但氯仿提取物在24~48 h内对雌蛾有显著的产卵促进作用。

摘  要:
Oviposition deterring effect of the different solvent(petroleum ether,chloroform and ethanol) extracts from a host plant(Nicotiana tabcum) and two nonhost plants(Populus yunnanensis and Eucalyptus globulus) on Phthorimaea operculella L were bioassayed.The results indicated that each plant contained chemicals deterring oviposition of the moth females.Petroleum extract of tobacco did not deter egg-laying by the moth females.Ethanol extract of tobacco showed significant oviposition deterrence to moth females at 0~24 h,while chloroform extract of tobacco did at 0~48 h.PE,EE and CE of Eucalyptus globulus demonstrated significant oviposition deterrence to moth females only at 0~24 h,but CE could significantly stimulate oviposition of the moth females at 24~48 h.
