Electro antennas

Recording of an electroantennogram as a function of the odor flow concentration.

In the case of an electrical antenna diagram (EAG), the electrical signal from a sensor (also called an antenna) of an insect is recorded and displayed. The method was developed by the German zoologist Dietrich Schneider .

This method is used, for example, to determine which fragrances and pheromones an insect can perceive. Usually the antenna of the anesthetized insect is prepared and the EAG is recorded with a special device. With this biosensor, pheromones can still be measured in concentrations that are 1000 times below the detection threshold of conventional chemical detectors. The measuring method is used to optimize the use of pheromones in the confusion method in wine and fruit growing .
