BIOGENIC 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...

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 کاملLimited effect of reactive oxygen species on the composition of susceptible essential amino acids in the midguts of Lymantria dispar caterpillars.
The essential amino acids (EAAs) arginine, histidine, lysine, and methionine, as well as cysteine (semiessential), are believed to be susceptible to reactions with reactive oxygen species (ROS) in biological systems. The decreased availability of these EAAs could harm insect nutrition, since several of them can also be limiting for protein synthesis. However, no in vivo studies have quantified ...
متن کاملLymantria dispar nucleopolyhedrovirus hrf-1 expands the larval host range of Autographa californica nucleopolyhedrovirus.
The gypsy moth (Lymantria dispar) is nonpermissive for Autographa californica nucleopolyhedrovirus (AcNPV) infection. We previously isolated a gene, host range factor 1 (hrf-1), from L. dispar nucleopolyhedrovirus that promotes AcNPV replication in Ld652Y cells, a nonpermissive L. dispar cell line (S. M. Thiem, X. Du, M. E. Quentin, and M. M. Berner, J. Virol. 70:2221-2229, 1996). In the presen...
