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 wate

Recombinant baculoviruses were constructed that express the cDNA encoding the prothoracicotropic hormone (PTTH) of Bombyx mori. This hormone stimulates the production of ecdysteroids by the insect's prothoracic glands. Two groups of viruses were cons

A 1355 bp sequence (accession number L32141) isolated from a gypsy moth (Lymantria dispar) cDNA library showed 68-74% sequence identity to mitochondrial large subunit ribosomal RNA (mt IrRNA) sequences of Locusta migratoria, Apis mellifera, Aedes alb

Production of sex pheromone in females of the gypsy moth, Lymantria dispar , is regulated primarily by a pheromonotropic factor originating in the head. Decapitation of a female caused depletion of pheromone in the pheromone gland; however, in contra

Results from ligation experiments performed on Lymantria dispar revealed a critical period for the terminal abdominal segment (TAS) in the control of larval and pupal molting. Fifth (last) instars abdominally ligated earlier than day 6 failed to pupa

1. 1. Feeding of thyroxine to larvae of the bivoltine silkworm. Bombyx mori L. resulted in increased pupal hemolymph protein and ecdysteroid levels, increased yolk deposition and accelerated oocyte maturation. 2. 2. Due to early yolk deposition, matu

The production of ecdysteroid by the insect prothoracic glands (PTGs) is initiated by an ecdysiotropin, prothoracicotropic hormone, which is produced by the brain and released into the hemolymph from its neurohemal organ. Recently we reported the dis

Hemolymph ecdysteroid titers and in vitro prothoracic gland ecdysteroid synthesis have been examined in last-instar larval (5th instar) females of Lymantria dispar. Ecdysteroids were quantified by radioimmunoassay and characterized by co-elution with

Brains from non-diapause-bound, diapause-bound and diapausing European corn borers contain prothoracicotropic hormone (PTTH) which stimulates the prothoracic glands of both Lymantria dispar and Ostrinia nubilalis to produce ecdysone and 3-dehydroecdy

Prothoracicotropic hormone (PTTH)-like activity was obtained from embryonated eggs of the gypsy moth, Lymantria dispar. Activity was detected using an in vitro prothoracic gland stimulation bioassay. Doseresponse kinetics of crude extract revealed a
