Red Palm Weevil, Rhynchophorus ferrugineus (RPW) is a new invasive species that has infested coconut trees along the coastline of Terengganu. It has also shown signs of plague in the inland of Peninsular Malaysia. Entomopathogenic fungi (EPF) is a natural antagonist of insects that has huge potential to be developed as bio-insecticides. Indigenous EPF has acclimatized to harsh environment and therefore would be effective to combat RPW. In this study, seven isolates of EPF (MetGra-1 – MetGra-7) were isolated from the soil samples and bioassay was performed against the adult RPWs by evaluating the mortality and hyphae growth on RPW cadavers. MetGra-4 and MetGra-7 showed promising results as first mortalities were observed on the 4th and 5th day respectively. Both strains achieved 100% cumulative mortality by 20th day of inoculation. The ET50 was achieved on eighth day for MetGra-7 and tenth day for MetGra-4. This study on indigenous EPF served as a platform to search for potential bio-pesticide against the RPW threat that could affect the economics of coconut and palm oil industries.
