dc.description.abstractEntomopathogenic fungi are considered to play a vital role as a biologi- cal control agent of many insect populations. Different entomopathogenic fungi were observed infecting Eriococcus ironsidei Williams (Hemiptera: Eriococcidae) in a macadamia nut orchard in Honokaa, Hawaii. Here, we report the results of the isolation of the unidentified fungal pathogens observed infecting E. ironsidei on macadamia leaves and their identification using molecular techniques. We evaluated the susceptibility of E. ironsidei to the isolated fungi and to one com- mercial formulation of the entomopathogenic fungus, Beauveria bassiana. To assess whether any of the isolated pathogens have potential to serve as biocontrol agents, E. ironsidei was exposed to isolated fungi. Identified entomopathogens were Chlorocillium griseum and Pleurodesmospora coccorum. Results of this study confirmed that C. griseum, P. coccorum, and B. bassiana cause mortality in E. ironsidei up to 67%, 78%, and 100%, respectively. The present investigation indicates that E. ironsidei is highly susceptible to these fungi and they may have a role in regulating insect pest populations.
