This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.
本文用"Y"形嗅觉仪法和培养皿法测试了山楂叶螨Tetranychus viennenis Zacher对不同植物气味物质的嗅觉反应,并利用固相微萃取SPME吸附、用气相色谱—质谱联用仪GC-MS(gas chromatograph-mass spectrometer)分析了不同植物叶片的挥发性物质成分:同时采用海绵水盘法饲养山楂叶螨,研究了不同植物对山楂叶螨生长发育的影响,并测定了不同植物叶片中一些生化物质的相对含量。

Based on the array signal processing and the eigenstructure decomposition method, the signal subspace and the noise subspace are achieved by reconstructing and decomposing the data matrix collected by the array sensors. By using the orthogonal properties of the two subspaces, the information about the velocities and bearings of spatial moving targets can be exactly obtained.
