Within-host interactions of lymantria dispar (Lepidoptera: lymantriidae) nucleopolyhedrosis virus and entomophaga maimaiga (Zygomycetes: entomophthorales)
The interaction of two gypsy moth (Lymantria dispar) pathogens, a nucleopolyhedrosis virus (LdNPV) and a fungus (Entomophaga maimaiga), were studied by assessing mortality among dually inoculated hosts. When fourth and fifth instar gypsy moths were inoculated with a range of doses of LdNPV and a fixed dose of E. maimaiga on the same day, the majority of larvae died from E. maimaiga infections r...
متن کاملImpact of Entomophaga maimaiga (Entomophthorales: Entomophthoraceae) on outbreak gypsy moth populations (Lepidoptera: Erebidae): the role of weather.
The fungal pathogen Entomophaga maimaiga Humber, Shimazu, and Soper is prevalent in gypsy moth [Lymantria dispar (L.)] populations throughout North America. To understand how weather-related variables influence gypsy moth-E. maimaiga interactions in the field, we measured fungal infection rates at 12 sites in central Pennsylvania over 3 yr, concurrently measuring rainfall, soil moisture, humidi...
متن کاملAminopeptidase-Like Activity in Hemolymph Plasma from Larvae of the Gypsy Moth, Lymantria dispar (Lepidoptera: Lymantriidae)
Aminopeptidase was isolated from the plasma fraction of hemolymph from last instar larvae of the gypsy moth Lymantria dispar. Activity was detected using the synthetic substrate L-alanine-4-nitroanilide. Total aminopeptidase activity per microliter of plasma varied with developmental stage. Activity was detected throughout the last (fifth) larval instar and increased throughout the pupal stage....
متن کاملDiscovery of Entomophaga maimaiga in North American gypsy moth, Lymantria dispar.
An entomopathogenic fungus, Entomophaga maimaiga, was found causing an extensive epizootic in outbreak populations of the gypsy moth, Lymantria dispar, throughout many forested and residential areas of the northeastern United States. This is the first recognized occurrence of this or any entomophthoralean fungus in North American gypsy moths, and its appearance was coincident with an abnormally...
متن کاملA survey of hymenopteran parasitoids of forest macrolepidoptera in the central Appalachians.
In 1995 and 1996, we conducted a study of the hymenopteran parasitoids of macrolepidopteran larvae in the George Washington National Forest (GWNF), Augusta County, Virginia, and the Monongahela National Forest (MNF), Pocahontas County, West Virginia. Macrolepidopteran larvae were collected from canopy foliage and from under canvas bands placed around tree boles. A total of 115 macrolepidopteran...
