The rhinoceros beetle, Oryctes rhinoceros, is a ubiquitous pest of oiJ palm. A survey conducted in a heavily infested five-hectare plantation revealed that dumped heaps of oil palm mesocarp waste serve as ideal breeding sites for beetles. Within a year a total of 2303 grubs, 32 pupae and 126 adult beetles could be collected from the heaps. Hence mesocarp waste should be either spread in the plantation instead of being kept as heaps or should be kept after treatment with some eco-friendly insecticides.The Baculovirus oryctus being an important tool in IPM, which is disseminated by the release of inoculated beetles necessitated their mass rearing. A comparative evaluation of the various rearing materials revealed that oil palm mesocarp waste is the best media followed by cow dung.The percentage of adult emergence in mesocarp waste was 72 ± 8.36 compared to 50 ± 4.47 in cow dung; 6 ± 2.45 in coir dust and nil in oil palm bunch refuse. Cement rings (95 cm x 30 cm) covered with double-layered chicken wire mesh were used as rearing cages, which provided protection from predators, good aeration, easy watering and observation.This technique proved to be ideal for mass rearing under laboratory conditions.
