COMPATIBILITYTESTOFTRICHODERMA VIRENS ANDMETARHIZIUM ANISOPLIAE ANDTHEIR ABILITY TO CONTROL ORYCTES RHINOCEROS LARVAE IN COMPOST

Oryctes rhinoceros is a major pest in oil palm plantations. The control often used is Metarhizium anisopliae, and also Trichoderma sp. Which have beein reported to be able to control pests. This study aims to test the compatibility of Trichoderma virens and Metarhizium anisopliae entomopathogenic fungi and the effectiveness of their combination in controlling Oryctesrhinoceros larvae in oil palm empty fruit bunches (OPEFB) compost media. This study consists of two stages, namely in vitro compatibility test on potato dextrose agar (PDA) media and testing the effectiveness of the combination of T. virens and M. anisopliae on the mortality of O. rhinoceros larvae with a completely randomized design (CRD).
