Abstract

<p>As a preliminary survey to develop suspended-soil arthropods as a new isolation source of entomopathogenic fungi, we investigated the entomopathogenic fungi of these arthropods. Fifty-five suspended-soil arthropods were collected from lowland tropical rainforests in East Kalimantan, and ten fungal isolates belonging to seven entomopathogenic species, including two undescribed species, were isolated from nine of the arthropods. Only two of the seven entomopathogenic species were commonly found from the arthropods inhabiting the ground soil in the same forests. The percentage of entomopathogenic fungi-positive arthropods from suspended soil was similar to that from ground soil of the same and another forest of the region, and lower than that from ground soil of Japan. However, the number of entomopathogenic species isolated from the suspended-soil arthropods was larger than that from ground-soil arthropods. This result suggests that suspended-soil arthropods can be a new isolation source of entomopathogenic fungi.</p>
