摘　　要：Olfactory respones of Tetranychus viennensis to different plants odors with “Y” olfactometer and petri-dish was studied and volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS. It was showed: Olfaction takes part in the response during the Hawthorn Spider Mite looking for host plants, indicating %Tetranychus viennensis% were attracted by odors from host plants. Different host plants have different attraction to the %Tetranychus viennensis%, some attract strongly, some were less than the others. The non host plants were tested have neither attraction nor repulsion to the mite. The volatile from leaves of different host plants such as %Malus pumila, Pyrus bretschneideri, Amygdalus persica,Armeniaca vulgaris, Malus spectabili, Crataegus pinnatifida, Prunus yedoensis%, etc. Consists of trans-3-hexen-l-ol,acetate, trans-3-hexenyl ester butanolc acid, alpha farensene, etc., which do not exist in the non-host plants such as Euonymus japonicus.Olfactory respones of Tetranychus viennensis to different plants odors with “Y” olfactometer and petri-dish was studied and volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS.
