Abstract
Natural iridescent virus and rickettsia infections of Costelytra zealandica (White) and Odontria sp. indet. larvae were studied at a site in the upper Pareora Gorge scenic reserve, S. Canterbury. By sequentially sampling the site, it was found that neither the iridescent virus nor the rickettsiae appear to give rise to host mortalities that significantly alter the population density. Many larvae were found that appeared healthy, but carried inapparent iridescent virus infections. These diseases are not suitable for biological control of the grass grub.Keywords
