中文摘要：
为了探究寄主气味挥发物对桔小实蝇行为的影响，本研究应用Y型嗅觉仪测定了桔小实蝇 Bactrocera dorsalis (Hendel) 成虫对5种芒果气味挥发性物质(乙酸乙酯, α-蒎稀, 异松油烯, 3-蒈烯和石竹烯)及5种物质混合物的行为反应。结果表明, 桔小实蝇雌、雄虫对5种物质及5种物质混合物的行为反应无显著性差异。结果还揭示, 桔小实蝇成虫对乙酸乙酯有明显的趋性反应，对异松油烯有明显的忌避反应，而对α-蒎烯、3-蒈烯、石竹烯和5种物质的混合物均没有明显的行为定向反应。说明桔小实蝇成虫对芒果不同气味挥发物的行为反应存在差别,这可为研发桔小实蝇成虫防治新方法提供基础信息。
英文摘要：In order to explore behavioral responses of Bactrocera dorsalis (Hendel) to host odor volatiles，the test of behavior of B. dorsalis to five kinds of odor volatiles of mango ( ethyl acetate，α-pinene，terpinolene， 3-carene and caryophyllene) and the mixture of these five volatiles was conducted with Y-tube olfactometer in laboratory. The results showed that female and male adults of the fruit fly had no significantly different behavior response to five kinds of odor volatiles and their mixture. The results also revealed that adults of B. dorsalis preferred to ethyl acetate，but refused terpinolene significantly. Moreover，adults showed no distinct directional behavior to α-pinene，3-carene，caryophyllene and the mixture of five volatiles. All results indicated that adults of fruit fly showed different behavior responses to odor volatiles of mango，which may provide useful information of studying new methods to control adults of fruit fly.
