Abstract
An epizootic caused by Furia virescens (Thaxter) Humber (Zygomycetes: Entomophthorales) was studied in a population of armyworms, Pseudaleti a unipuncta (Haworth), in a tall fescue, Festuca arundinacea Schreber (Poaceae), pasture in Arkansas. Prevalence rates in live larvae collec ted hom the field were 21.6, 8.1 and 13.5% for F. virescens, the braco nid parasitoid Glyptapanteles militaris (Walsh), and an unidentified m ermithid nematode, respectively. In a laboratory trial one Heliothis v irescens (F.) larva was infected by F. virescens. Previously unrecorde d aspects of the morphology and life cycle off. virescens are describe d. Pseudaletia unipuncta and H. virescens are new host records for F. virescens.
