Ocorrência do fungo entomopatogênico Isaria javanica (Frieder. & Bally) Samson & Hywell-Jones (Fungi, Sordariomycetes) em lagartas de Lonomia obliqua Walker (Lepidoptera, Saturniidae, Hemileucinae)

It is recorded for the first time the occurrence of the entomopathogenic fungus Isaria javanica (Frieder. & Bally) Samson & Hywell-Jones (Fungi: Sordariomycetes) infecting Lonomia obliqua Walker (Lepidoptera: Saturniidae: Hemileucinae) caterpillars. This fungus was isolated from L. obliqua individuals collected from Platanus acerifolia (Aiton) Wild- Platanaceae in Rio Grande do Sul state, Brazil. After isolation, purification and characterization, fungal conidia were inoculated on healthy L. obliqua caterpillars and from dead caterpillars the fungal isolates were again obtained. New isolates and the original isolate did not differ when compared by morphological and molecular tests.
