Oryctes rhinoceros populations and behavior influenced by a baculovirus
Journal of Invertebrate Pathology 29 (2), 210-215
Abstract: Oryctes rhinoceros adults stopped feeding and flew less frequently, and the males mated less often after they became infected with the baculovirus of Oryctes. Monitoring the larval and adult population in Western Samoa over several years gave evidence that the incidence of the virus is dependent on the density of the O. rhinoceros population. Male beetles were more frequently infected than female beetles. Adding more virus-infected beetles to the O. rhinoceros populations of Nukunonu Atoll, where the virus had become established 5 years earlier, reduced the population significantly. The data indicated that the reduction was caused mainly by a decrease in the number of eggs deposited.
