Abstract
Abstract The host range of Coelomomyces opifexi was investigated. Of the three species of mosquito larvae tested, Aedes australis and Opifex fuscus were susceptible whereas Culex pervigilans was refractory to infection. The results of laboratory infection experiments using inoculum derived from larvae of both species clearly indicated that Ae. australis larvae are more susceptible to infection than O. fuscus; this conclusion is supported by observations of natural infection pools. Of three species of copepods also tested, only Tigriopus sp. cf. angulatus became infected; Cyclops vernalis and C. bicuspidatus proved refractory to infection.
