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 beta-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.
采用顶空固相微萃取和气相色谱-质谱联用方法，并使用Y型嗅觉仪，对6个番茄品种（浙杂809、浙杂203、合作903、凯特一号、黄托燕和金妃）的挥发性物质进行了鉴定，并对B型烟粉虱雌虫对番茄植株及其释放的挥发性物质的嗅觉反应进行了生物测定。从6个番茄品种中收集的挥发性物质中鉴定出13种化合物，其中萜类化合物是主要成分。然而，挥发性物质的组成和含量因番茄品种而异。(+)-3-蒈烯和β-石竹烯对B型烟粉虱的驱避性比其他萜类化合物更强。B型烟粉虱对浙杂809和浙杂203等萜类化合物种类较多且挥发性物质中萜类化合物比例较高的番茄品种偏好最低，对黄托燕和金妃等萜类化合物种类较少且挥发性物质中萜类化合物比例较低的品种偏好最大。
