Inheritance 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 کاملWorld distribution of female flight and genetic variation in Lymantria dispar (Lepidoptera: Lymantriidae).
Female gypsy moths, Lymantria dispar L., from 46 geographic strains were evaluated for flight capability and related traits. Males from 31 of the same strains were evaluated for genetic diversity using two polymorphic cytochrome oxidase I mitochondrial DNA restriction sites, the nuclear FS1 marker, and four microsatellite loci. Females capable of strong directed flight were found in strains tha...
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 کاملWithin-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 کاملBIOGENIC AMINES IN PROTOCEREBRAL A2 NEUROSECRETORY NEURONS OF Lymantria dispar L. (LEPIdOPTERA: LYMANTRIIdAE) – RESPONSE TO TROPHIC STRESS
The number, morphometric parameters and amount of aminergic neurosecretory product of protocerebral A2 neurosecretory neurons were investigated in the fifth instar of Lymantria dispar caterpillars, following a suitable or unsuitable trophic regime. Caterpillars originated from two populations (Quercus rubra or Robinia pseudoacacia forest) and were differently adapted to trophic stress, i.e. fee...
