Preliminary survey for entomopathogenic fungi associated with Ixodes scapularis (Acari: Ixodidae) in southern New York and New England, USA

摘要

Free-living larval, nymphal, and adult I. scapularis were collected from scattered locales in southern New England and New York in June-November 1997 to determine infection rates with entomopathogenic fungi. Infection rates of larvae, nymphs, males,and females were 0% (571), 0% (272), 0% (57), and 4.3% (47), respectively. Two entomopathogenic fungi were isolated from field-collected I. scapularis females from Fire Island, New York. Isolates were identified as Verticillium lecanii and Verticilliumsp. (a member of the V. lecanii species complex).
