$)C Dear Mycologyer I found Erynia species on aphids and tried to isolate the fungus. But I always encountered contamination and failed to isolate. Is there easy way for pure isolation of Erynia species? Cheol-Sik Yoon Nattional Institute of Agricultural Science and Technology Tel : 82-0331-290-0478 E-mail : csyoon at niast.go.kr
