Regulation of serpin gene-1 in Manduca sexta

Insect Biochemistry and Molecular Biology, 1995
Hemolymph of Manduca sexta contains proteins from the serpin superfamily, which are inhibitors of serine proteinases. We have used probes specific for M. sexta serpin gene-1 mRNA and protein to study the expression and hormonal regulation of this gene.

Ontogeny of electroantennogram responses in the moth, Manduca sexta

Journal of Insect Physiology, 1976
Abstract The antennae of the moth, Manduca sexta , and the sensilla and sensory neurons they contain, develop during metamorphosis from pupa to adult. To determine when, during their development, antennae become capable of generating electrical responses to various stimuli, we recorded the electroantennogram (EAG), believed to be the summed ...

Allatotropin is a cardioacceleratory peptide in Manduca sexta

Journal of Experimental Biology, 1994
ABSTRACT Allatotropin is a neuropeptide that was originally isolated from the sphinx moth Manduca sexta, in which it stimulates the synthesis of juvenile hormone in adults (Kataoka et al. 1989). An antiserum raised against this peptide was characterized, shown to be specific for allatotropin and used in a competitive enzyme-linked ...

Hemolymph Proteinases in Immune Responses of Manduca sexta

2001
Extracellular signal transduction pathways in blood are often composed of cascades of serine proteinases to amplify rapidly a response to wounding or infection. The vertebrate blood coagulation and complement pathways are the most fully characterized of such proteinase cascades.

Debraining and diapause development in Manduca sexta pupae

Journal of Insect Physiology, 1974
Debraining experiments with wounded and normal controls were done at three different ages on diapausing Manduca sexta pupae of Kentucky and Illinois stocks. With early ages of both stocks debrained pupae escaped from diapause over an extended period of time, but wounded insects developed much earlier and at the same time as the normals. With later ages

The innervation of the salivary gland of the moth, Manduca sexta

Cell and Tissue Research, 1974
The salivary glands of the moth, Manduca sexta (Insecta: Sphingidae), are unlike most other salivary glands in that they are innervated from one source only. Vital staining of nerves with methylene-blue reveals numerous fine nerves extending to the glands from the oesophageal nerve, a part of the stomatogastric or visceral nervous system.

Innervation of the heart and aorta of Manduca sexta

Journal of Comparative Neurology, 2001
AbstractInnervation of the heart and aorta of Manduca sexta was studied by using anatomic, neuronal tracing and immunocytochemical techniques. The study was undertaken to provide a foundation for investigating the neural mechanisms controlling cardiac reversal in adults. Lateral cardiac nerves were not found in the larval or adult heart.

The structure of the salivary gland of the moth (Manduca sexta)

Zeitschrift für Zellforschung und Mikroskopische Anatomie, 1973
The salivary glands of the moth,Manduca sexta, are described, emphasizing correlations between structure and function in an attempt to explain the production of a dilute saliva. Each of the paired glands consists of five distinct regions: protein secreting, fluid secreting, thin duct, bulbous duct, and common duct.

Studies on lipid transport in Manduca sexta (Insecta)

Comparative Biochemistry and Physiology, 1970
Abstract In vitro studies with the adult fat body of the tobacco hornworm, Manduca sexta, indicate that when the moth ingests glucose, the sugar is converted to lipid which is released from the fat body into the haemolymph as diglyceride.

Absorption and storage of phosphorus by larval Manduca sexta

Journal of Insect Physiology, 2002
The role of phosphorus (P) in numerous important biological structures, coupled with the observation that P-content of many insect foods is disproportionately low, suggests that P may be a critical nutrient for growing insects - however, the few studies examining the effects of dietary P on insect performance have generally found only weak ...
