Abstract: A portable electronic nose (E-nose) based on metal oxide gas sensor was used for detection of a total volatile compound in soil headspace and greater wax moth (Galleria mellonella L.). Sensor elements were selected in order to possibly respond to a wide range of the volatiles including both of oxidizing and reducing gases. The aim of this work was to relate the soil volatile fingerprints at their depth levels and less number of greater wax moth that can be detected by electronic nose. Soil was sampled from the field of the vinery located near Khao Yai world heritage, Thailand at a depth level of 10 cm, 30 cm and 50 cm. Male and female greater wax moths were treated from egg to senile adult in plastic box and measured with electronic nose by varying number of moth. The results could identify the difference of the volatile fingerprints by employing principal component analysis (PCA) as the signal pattern recognition technique. The volatile profiles from eight TGS elements relating chemical emissions will be discussed in more details.
