Olfactory biosensor using four different insect antennae, named quadro-probe biosensor, was developed and the performance of the quadro-probe biosensor was evaluated in a wind tunnel and in fields. The quadro-probe could detect volatile and semi-volatile compounds with high sensitivity, and we were able to discriminate between different compounds in real time under field conditions using the quadro-probe biosensor. A portable detector system, combined the quadro-probe biosensor with a wind-direction indicator, could locate various hidden odor sources in fields.
