    Author: Ishay JS, Shimony T, Rosenzweig E, Avidor N, Afek AB.

    Abstract:
    Resistance to electricity by social wasp cuticle is temperature dependent within the range of 1--40 degrees C. This was measured on the species Vespa orientalis (the Oriental hornet), Vespa crabro (the European hornet) and the wasp Dolichovespula saxonica. The resistance at first decreases with increased temperature, reaching a nadir which differs according to species, and then rises again up to 40 degrees C, the highest temperature tested. It is suggested that the cuticular changes in resistivity at different temperatures reflect the wasp's mechanism for detecting and regulating the temperature in their normal environment.
