Staghorn sumac, Rhus typhina, an introduced tree species in China in 1959 as an ornamental plant and it has been growing very well with high resistance to pests including mites. For determining the substances of its resistance to two economically important mites, Tetranychus urticae Koch and T. viennensis Zacher, the volatiles in the R. typhina leaves were collected with solid phase microextraction (SPME) and their constituents were identified with GC-MS. The main compounds of foliar volatiles and the order of the content from high to low were as follows: phenol,4,6-di(1,1-dimethyl ethyl)-2-meth, 4-heptanol, 2,6,10-dodecatrien-1-ol, 3,7,11-trimethyl-, butylated hydroxytoluene, alpha.-farnesene, 1-octadecene, 1-penten-3-ol,4-methyl-, methyl salicylate and benzoic acid, ethyl ester. The influence of foliar volatiles on attraction to T. urticae Koch and T. viennensis Zacher was determined by Y-tube olfactometer. In two groups of foliar volatiles, i.e. Staghorn sumac vs. apple and Staghorn sumac vs. clear air, the attractive percentage of T. urticae to Staghorn sumac was 9.3% and 28.9% and that of T. viennensis was 5.6% and 28%, respectively. It was showed that the difference of the attractive percentage between Staghorn sumac leaves and controls was significant, while the difference between the two provided mites was insignificant. It was indicated from above results that the foliar volatiles of Staghorn sumac had certain roles on the attractive and selective behaviors of the two mites.
