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 کاملUnusual Degradation Pathway of Pheromone Odorants in Gypsy Moth
Gypsy moth is a major pest in Europe and North America. The closely related species, nun moth, is also a destructive pest in Europe. Both species use the pheromone cis 7(R), 8(5')-2-methyl-7, 8-epoxyoctadecane, (+)-disparlure, for sexual communication. The alkene precursor of disparlure, 2-methyl-7(Z)-octadecene, and (-)-disparlure are also of biological importance in both species. In this thes...
متن کاملA Web-based Expert System for Gypsy Moth Risk Assessment
The gypsy moth is one of North America's most devastating exotic forest pests because it can cause the loss of valuable oak species, degraded aesthetics, loss of wildlife habitat, and detrimental effects on watersheds. Due to the increasingly wide infestation of the gypsy moth, it is important to develop decision aids that help assess the risks of this pest to our forests. Expert systems are a ...
