Malczewska, M. and Cymborowski, В.: Cold-induced supernumerary moults of Galleria mellonella larvae as bioassay for anti-juvenile hormone compounds. Acta physiol, pol., 1988, 39 (2): 112-120. Application of selected anti-juvenile hormone compounds to freshly moulted and chilled Galleria mellonella last instar larvae inhibits the incidence of supernumerary moultings in a dose-dependent manner. This indicates that the chilling Galleria larvae can be used as a simple and reliable bioassay for testing an anti-juvenile hormone activity of various agents. This bioassay is also very convenient for investigation of the mechanism of actions of these compounds.
