摘　　要：为探讨茶园群落中非茶植物气味引诱或驱避重要茶树害虫假眼小绿叶蝉的效应,遂将茶园常见杂草迷迭香挥发物中樟脑、α-松油醇和石竹烯分别配成10-2g/m L剂量,再等量组成混合物,在每个橡皮头上载100#L制成诱芯,附于素馨黄粘板上,于茶园中诱捕假眼小绿叶蝉,发现这种三组分诱芯明显地驱避假眼小绿叶蝉。将行为反应中分别对假眼小绿叶蝉呈现显著引诱效应的10-2g/m L樟脑、10-4g/m L石竹烯、10-6g/m Lα-水芹烯、10-4g/m Lα-松油醇和10-8g/m L桉树脑等量配成五组分混合物,同法制成诱芯,附于素馨黄粘板,诱捕假眼小绿叶蝉。发现五组分诱芯:(1)显著引诱假眼小绿叶蝉,诱效稍强于现价段茶园中使用的源于茶梢挥发物的诱芯;(2)每日诱捕的假眼小绿叶蝉数与天数呈抛物线关系;(3)加入液体石蜡作为缓释剂,可将诱效的半衰期延长2.5—4.0d;(4)18:00—6:00诱得的假眼小绿叶蝉数量占全天的70%—75%。分析认为:非茶植物迷迭香的挥发物中含有显著引诱假眼小绿叶蝉信息物质,这类信息物质制成的五组分诱芯的诱效较强,可以作为一种防治假眼小绿叶蝉的手段,早晨和黄昏是最佳诱捕时分。In order to explore the effectiveness of using a Push-Pull strategy on control of the tea green leafhopper in tea plantation community, non-tea plant odors from rosemary, such as camphor, α-terpineol, and caryophyllene were tested at a dosage of 10 mg per mL. A blend containing the equivalent amount of above mentioned three compounds was loaded into a rubber septum. The jasmine yellow sticky board baited with the lure was tested in the tea plantation to trap tea green leafhoppers. The results showed that it actually repelled tea green leafhoppers, instead of being attracted. However, a blend of 5 components （camphor： caryophyllene： phellandrene： a-terpineol： eucalyptol at 10 mg： 0.1mg： 0.001mg： 0.1mg： 0. 00001mg per mL） displayed strong attraction to tea green leafhopper inY-tube olfactometer bioassay. Further field tests revealed that： （1） this five-component lure were remarkably attractive to tea green teafhoppers, and its trapping efficacy was slightly better than that of the lure with tea shoot volatiles that had been demonstrated previously ; （2） A parabolic curve relationship was shown between the number of tea green leafhoppers trapped and trapping days ; （3） further development of the lure in liquid paraffin as a slow release carrier was demonstrated to prolong the lure longevity from 2.5 to 4.0 days; （4） over 70% of tea green leafhoppers were caught from 6 pm to 6 am. In conclusion, baits with 5 components of volatiles from rosemary were attractive to tea green leafhoppers that can be used for pulling them into the traps, whereas the repellency of the three component blend can be deployed for driving them away from the tea plantation as a push component
