The influence of CIV infection was tested on the last instar larvae of rice stem borer, Chilo suppressalis WALKER and greater wax moth, Galleria mellonella L. The larvae of these insects were easily infected by the injection of CIV. The abnormality of metamorphosis was observed in the infected larvae : supernmerary larvae or larval-pupal intermediates in various grades were obtained depending on the progress of the inoculation periods as in the case of juvenile hormone treatment. Some of Galleria larvae treated at the late stage of the last instar developed into second pupae after an extra pupal ecdysis. When the penultimate instar Galleria larvae were infected with CIV, they ecdysed to the last instar larvae, which survived more than two months without any sign of the pupal ecdysis. The inoculated pupae did not display any abnormality of metarmorphosis, though they showed iridescence in their various tissues. The inoculation at a high concentration of CIV inactivated by either UV-irradiation or heat-treatment induced neither appearance of iridescence nor the abnormality of metamorphosis of Galleria larvae.
