Aminopeptidase-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 کاملInheritance of female flight in Lymantria dispar (Lepidoptera: Lymantriidae).
A clinal female flight polymorphism exists in the gypsy moth, Lymantria dispar L., where female flight diminishes from east to west across Eurasia. A Russian population where females are capable of sustained ascending flight and a North American population with females incapable of flight were crossed: parentals, reciprocal F(1) hybrids, double reciprocal F(2) hybrids, and all possible backcros...
متن کاملA novel low molecular weight ecdysiotropin in post-diapause, pre-hatch eggs of the gypsy moth, Lymantria dispar L. (Lepidoptera: Lymantriidae).
Extracts of post-diapause, pre-hatch eggs of the gypsy moth, Lymantria dispar L. were examined for prothoracicotropic hormone (PTTH)-like activity using an in vitro assay involving last-instar prothoracic glands (PGs). The eggs were extracted in water, eluted from a low-pressure C18-silica cartridge in 60% acetonitrile, and fractionated on a high-performance, size-exclusion column. The primary ...
متن کاملInteractions between a Nosema sp. (Microspora: nosematidae) and nuclear polyhedrosis virus infecting the gypsy moth, Lymantria dispar (Lepidoptera: lymantriidae).
Simultaneous and sequential per os inoculations of gypsy moth larvae with the Lymantria dispar nuclear polyhedrosis virus (LdNPV) and a Nosema sp. from Portugal demonstrated that the interaction of two pathogens during coinfection was variable, ranging from synergistic to antagonistic. Susceptibility of gypsy moth larvae to viral infection was unaffected by simultaneous and subsequent microspor...
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...
