摘　　要：经气相色谱-质谱联用仪(GC/M S)分析,从马缨丹(L antana cam ara L.)挥发油中检测出43种化学成分。在各种成分中,桉树脑含量最高(11.761%),其次是反式-石竹烯(10.483%)、β-蛇床烯(7.509%)。马缨丹挥发油对美洲斑潜蝇的产卵、取食行为的影响结果表明,它对成虫的驱避和拒食作用都随挥发油施用量的增加而趋于显著,但随着时间的延长而降低。采用四臂嗅觉仪对美洲斑潜蝇成虫的行为反应的测定结果表明,美洲斑潜蝇成虫对这种挥发油具有相同的行为趋向。From essential oil of Lantana carnara, 43 compounds were checked out by using GC/ MS. Bioassay showed that essential oil with different concentration had oviposition deterrent effect and antifeeding effect against Liriomyza sativae. Furthermore, the effect enhanced with concentrations increasing while weaked with time. At the same time, four-armed olfactomater test also showed that volatiles of Lantana camara influenced behavior of Liriornyza sativae strongly.
