Research on the diversity and abundance of entomopathogenic fungi and their hosts in rice plantations in Bolaang Mongondow Regency was an attempt to find potential local biological control agents. Integrated pest management as often employed in agricultural pest control, may be a way to address these issues. The purpose of this study was to determine the diversity and abundance of entomopathogenic fungi and their hosts, to find pest insect species that attack rice plants, and to look for potential host species and entomopathogenic fungi in Bolaang Mongondow. The results showed that entomopathogenic fungi that have been identified through the research are Beauveria bassiana, Hirsutela sp., and Metarhizium anisopliae. Hosts that have been found due to fungal entomopathogenic infections are Nilaparvata lugens, Scotinophara coarctata, Leptocorisa oratorius, and Paraeucosmetus pallicornis. The highest diversity index in Bolaang Mongondow was found in Nilaparvata lugens (1.07) and for entomopathogenic fungi was found in Beauveria bassiana (1.34). The highest abundance index levels in Bolaang Mongondow were found in the same host and fungi.
