A Paraisaria-like fungus isolated from a larva of a
cerambycid beetle, Anopolophora oshimana, produced small
obovoid conidia from
multi-necked conidiogenous cells arising from synnematous conidiophores.
In
culture, the fungus produced curved Harposporium-like
conidia in addition to obovoid conidia. When introduced into
nematode-infested cultures, nematodes were infected after ingesting
the curved conidia and infection typical of Harposporium,
producing curved conidia from globose conidiogenous 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.
