Die Registrierung der Stridulationsbewegungen bei der Feldheuschrecke Chorthippus mollis mit Hilfe von Hallgeneratoren

Abstract

A method is described for measuring directly the stridulation movements of acridids using the Hall-effect. A double Hall-generator is fixed on the back of a freely moving grasshopper (Fig. 3a). A small permanent magnet is fastened on the femur of the hindleg in such a way that, during stridulation, it moves along the length of the Hall-generators. The… (More)
