摘　　要： 植物在受到昆虫侵害时会产生挥发性物质。因此,利用电子鼻与计算机组成水稻虫害快速检测系统,通过检测水稻挥发物气味,根据气味信息的分类,选用主成分分析法可快速判断水稻是否有虫害及每株水稻上有多少害虫。研究发现,利用电子鼻检测水稻虫害的最好时机是在水稻受侵害的15～36h内。实验结果证明,利用电子鼻检测水稻是否发生虫害及发生虫害后每株水稻上害虫的数量是可行的。 In response to insect herbivory,plants synthesize and emit blends of volatile compounds from their damaged and undamaged tissues. A system,comprised of computer and electronic nose could fast detecting the blends of volatile of paddy rice. The method for fast detecting insect pest information of paddy rice included detecting the volatile odor,classifying volatile odor by insects,and using principal component analysis. The best opportunity for detecting insect pest information using electronic nose was found out,it was between 15 to 36 hour after insect herbivory. The results of this experiment demonstrated that using electronic nose to inspect insect pest information of paddy rice was efficient.
