Temperature Dependence of Electrophysiological Responses of Lepidopteran Antennae*

Electroantennogram, Electrosensillogram, Optimum Curves, Hysteresis, Temperature Dependence By recording the temperature dependence of electroantennograms with Lepidoptera antennae optimum curves were obtained, and a hysteresis phenomenon was observed by passing tempera­ ture cycles. The latter also occur with single cell recording (electrosensillogram) in the receptor potentials as well as in the number of action potentials released per second. The results of the measurements are discussed on a molecular level, a scheme reflects the molecular processes which eventually are involved in the interaction of a signal molecule and receptor region.
