Abstract: The behavioral responses of Bemisia tabaci MED adults to volatile compounds of 14 plants were determined using Y-tube olfactometer. Using different combinations of plant volatiles and yellow sticky trap, the optimum combinations of plant volatiles and yellow sticky trap were evaluated by comparing the trapping catches of B. tabaci adults. Ten percent of 1,8-cineole, eugenol, myrcene, limonene and cinnamaldehyde showed attractiveness to adults of B. tabaci, 1,8-cineole and myrcene being significantly effective (P<0.001). While cis-3-hexene-ol pinene and pentene showed repellency, cis-3-hexene-ol pinene being stronger. At 1%, 1,8-cineole, eugenol, myrcene, ethyl nicotinate and nerol were attractive to B. tabaci adults significant in 1,8-cineole and eugenol (P<0.01). In contrast, repellency response to cis-3-hexene-ol pinene and pentene was detected. The combination of 10% 1,8-cineole+eugenol (at 1:1) and 1,8-cineole+myrcene showed relatively better attractiveness to B. tabaci. Meanwhile, in the field experiment, yellow sticky trap coated with 10% 1,8-cineole caught more B. tabaci. Our results show that plants volatiles can be effective attractant or repellent for B. tabaci, and the taxis response of B. tabaci to the same monomeric compound varies with compound concentration. Besides, pairwise mixing of monomeric compounds with consistent taxis response may not necessarily play the original role of taxis responses of the monomeric compound.
