摘　　要：采用顶空固相微萃取和气相色谱-质谱法鉴定了6个番茄品种(浙杂809、浙杂203、合作903、凯特一号、黄椭圆和金妃)植株挥发物的成分,并利用Y型嗅觉仪测定了烟粉虱对不同番茄品种植株及其挥发物的嗅觉反应.结果表明:从6个番茄品种中共鉴定出13种化合物,其主要成分为萜类化合物,品种间挥发物的组成成分和各成分所占比例存在差异.(+)-3-蒈烯和β-石竹烯对B型烟粉虱的驱避性较其他萜类强.烟粉虱对含萜类挥发物种类多、比例高的品种(如浙杂809和浙杂203)选择性较弱,而对含萜类挥发物种类少、比例低的品种(如黄椭圆和金妃)选择性较强.By the methods of headspace solid-phase micro extraction and gas chromatography-mass spectrometry,and using Y-type olfactometer,this paper identified the volatiles from six tomato varieties（Zheza 809,Zheza 203,Hezuo 903,Kate No.1,Huangtuoyan,and Jinfei）,and bio-assayed the olfactory responses of female B-biotype Bemisia tabaci to the tomato plants and their released volatiles.Thirteen kinds of compounds in the volatiles collected from the six tomato varieties were identified,among which,terpenoids were the main components.However,the compositions and contents of the volatiles differed with tomato varieties.（＋）-3-carene and β-caryophyllene showed stronger repellency than other terpenoids to B-type B.tabaci.B-type B.tabaci showed the lowest preference to the tomato varieties such as Zheza 809 and Zheza 203 which contained more kinds of terpenoids and had higher proportion of terpenoids in the volatiles,and showed the greatest preference to the varieties like Huangtuoyan and Jinfei which contained fewer kinds of terpenoids and had lower proportion of terpenoids in the volatiles.
