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 کاملPopulation Dynamics of Gypsy Moth in North America
The gypsy moth, Lymantria dispar, is a major defoliator of deciduous trees throughout the northern hemisphere. Introduced into eastern Massachusetts from Europe in 1868 or 1869, it has gradually spread south and west and will soon occupy most of the hardwood forests in the eastern United States and Canada. The gypsy moth has been the subject of intensive study by scientists throughout the world...

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 کاملCharacterization of Gypsy Moth (Lymantria dispar) Nuclear Polyhedrosis Virus.
Characterization of the proteins and nucleic acid of the gypsy moth nuclear polyhedrosis virus isolated in Ithaca, N.Y. (LdNPV-IT) is presented. A total of 29 viral structural proteins were identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis when the virus was isolated in the absence of alkaline protease activity. Fourteen surface envelope viral proteins were identified by l...
