Studies on Rhabdionvirus oryctes: I. Effect on Larvae of Oryctes rhinoceros and inactivation of the virus
Journal of Invertebrate Pathology 20 (3), 235-241
Abstract: The mortality rates and the periods of lethal infection are described for the larvae of Oryctes rhinoceros inoculated with Rhabdionvirus oryctes. Ground-up virus-killed larvae of O. rhinoceros were used to prepare the inocula. Similar median lethal dosages were estimated for the different larval stages and for larvae kept under different conditions of food, temperature, and humidity after the inoculation. The period of lethal infection was found to be dependent on the larval stage and on the surrounding temperature. Storage of Rhabdionvirus in sawdust for 1 week reduced the amount of active virus material in the mixture to 0.091% of its initial value. After 2 weeks the amount of active virus material was reduced to 0.027%, and no more infectivity was detectable after 1 month. Drying the mixture or raising the temperature increased the rate of inactivation. The sterilization effect of heat and of several chemicals on the virus was studied.
