Research and Application of Electronic Nose for Testing Stored-grain Insects

We use Alpha MOS Fox 3000 electronic nose made in France and the testing system made by ourselves to detect and compare the sample of stored wheat containing dead pests or live with standard air of different smells, and carry out pattern classification with main element analyse method.The results show that without regarding the number of pests, dead pest or live , the smell of the sample is different from standard air evidently. So we can detect whether the wheat is eaten by the pest immediately.
