A NEW SPECIES OF HARPOSPORIUM WITH 2 SPORE TYPES ISOLATED FROM THE LARVA OF A CERAMBYCID BEETLE

A Paraisaria-like fungus isolated from a larva of a cerambycid beetle, Anopolophora oshimana, produced small obovoid conidia from multi-neck ed conidiogenous cells arising from synnematous conidiophores. In cult ure, the fungus produced curved Harposporium-like conidia in addition to obovoid conidia. When introduced into nematode-infested cultures, n ematodes were infected after ingesting the curved conidia and infectio n typical of Harposporium, producing curved conidia from globose conid iogenous cells, resulted. Reinfection of beetle larvae by injection of hyphal bodies from pure culture and by contact with conidia from the original host showed pathogenicity to cerambycid larvae.
