Abstract
Oryctes rhinoceros L. (Coleoptera: Scarabaeidae) is one of the important pest in coconut and oil palm in Indonesia. The intensity of this pest attack was up to 69%. The use of natural agent in controlling O. rhinoceros is keep on improved, in order to gain an effective yield. One of natural agent from O. rhinocerospest is the entomopathogen Metarhizium sp. This research was aimed to gather some Metarhizium sp. isolate that has high virulence towards the O. rhinocerospest. The results showed that Metarhizium sp. isolate from Salatiga, Tegineneng, and Natar are able to infect and kill O. Rhinoceros larva in a short period of time and they have high virulence value. The field experiment showed that Metarhizium sp. isolate from Salatiga, Tegineneng, and Natar have lethal period, respectively 10.4, 11.0, and 11.0 days, while the virulence values are 0.096, 0.091, and 0.090.
