Entomopathogenic Hyphomycetes Associated with Gypsy Moth Larvae
Gypsy moth, Lymantria dispar, populations were sampled in four eastern North American states during 1991 and 1992 to evaluate levels of hyphomycete infection in association with releases of the Asian gypsy moth pathogen Entomophaga maimaiga. Paecilomyces farinosus was the most abundant hyphomycete species, occurring at the majority of sites, although levels of infection averaged only 4.6% (1991...
متن کاملCONIDIAL DISTRIBUTION OF FRESHWATER HYPHOMYCETES OF AN IRANIAN RIVER: ZAYANDE-ROUD
There is no published report regarding Iran's aquatic hyphomycetes. In an attempt to identify species of aquatic hyphomycetes in a river in central Iran (Zayande-Roud River), conidial frequency and distribution were determined by filtration. Water samples were collected monthly from two stations 55 km apart and filtered through millipore filters (5 um pore sizes). This was carried out for seven...
متن کاملFungi Associated with the Hemlock Woolly Adelgid, Adelges tsugae, and Assessment of Entomopathogenic Isolates for Management
Fungi associated with the hemlock wooly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), were collected throughout the eastern USA and southern China. Twenty fungal genera were identified, as were 79 entomopathogenic isolates, including: Lecanicillium lecanii (Zimmermann) (Hypocreales: Insertae sedis), Isaria farinosa (Holm: Fries.) (Cordycipitaceae), Beauveria bassiana (Balasamo) (Hyphom...
متن کاملInfluence of conidial traits and leaf structure on attachment success of aquatic hyphomycetes on leaf litter.
Attachment of conidia on leaves is a critical first step in the life cycle of aquatic hyphomycetes in streams. In a first series of microcosm experiments, attachment success of three common aquatic hyphomycete species differing in conidial shape (compact, filiform and tetraradiate) was determined on two leaf species, black alder and downy oak. Fungal species identity and leaf surface structure ...
متن کاملConidial viability assay for rapid susceptibility testing of Aspergillus species.
Antifungal susceptibility testing of filamentous fungi has become more important given the recognition of drug-resistant organisms and the availability of therapies other than amphotericin B (AMB). As current microdilution and E-test methods are limited by a 2 to 3 day incubation time required to obtain results, a more rapid method for susceptibility testing of fungi is needed. We report here a...
