Interaction between Manduca sexta allatotropin and Manduca sexta allatostatin in the fall armyworm Spodoptera frugiperda

Insect Biochemistry and Molecular Biology, 2000
A peptide that strongly stimulates juvenile hormone (JH) biosynthesis in vitro by the corpora allata (CA) was purified from methanolic brain extracts of adult Spodoptera frugiperda. Using HPLC separation followed by Edman degradation and mass spectrometry, the peptide was identified as Manduca sexta allatotropin (Mas-AT).

Effects of Manduca Diuresin on Neonates of the Tobacco Hornworm, Manduca sexta

General and Comparative Endocrinology, 2000
Manduca diuresin (MD), a 30 amino acid peptide, was isolated and identified from the type IIb median neurosecretory cells in the brain of adult Manduca sexta (Blackburn et al., Biochem. Biophys. Res. Commun., 181, 927-932, 1991). The synthetic hormone stimulates water loss in the adult moth both in vitro using isolated Malphigian tubule preparations ...

Serpins from an Insect, Manduca sexta

1997
Members of the serpin superfamily have been identified in several invertebrate species, primarily as proteins in the hemolymph of animals from the phylum Arthropoda9. Serpin cDNAs have been cloned from horseshoe crabs14,15, a crayfish13, two species of lepidopteran insects6,10,17,20,24, the fruit fly Drosophila melanogaster 3, trematodes from the genus

Associative olfactory learning in the moth Manduca sexta

Journal of Experimental Biology, 2000
The proboscis extension response conditioning protocol has been used to explore olfactory-based associative learning in an array of insects. We have monitored a different feeding reflex, which involves activation of the cibarial pump, to demonstrate olfactory learning in the moth Manduca sexta.

Messenger RNA in the cellular commitment of Manduca sexta

General and Comparative Endocrinology, 1981
Abstract RNA synthesized during the ecdysteroid-induced change of epidermal commitment in the tobacco hornworm has been investigated. Larvally and pupally committed cells do not show any qualitative differences in total RNA that can be detected on 7 M urea polyacrylamide gels.

Hematopoietic organs of Manduca sexta and hemocyte lineages

Development Genes and Evolution, 2003
Cells of the moth immune system are derived from organs that loosely envelop the four wing imaginal discs. The immune response in these insects is believed to depend on the activities of two main classes of hemocytes: plasmatocytes and granular cells.

Pattern recognition proteins in Manduca sexta plasma

Insect Biochemistry and Molecular Biology, 2002
Recognition of nonself is the first step in mounting immune responses. In the innate immune systems of both vertebrates and arthropods, such recognition, termed pattern recognition, is mediated by a group of proteins, known as pattern recognition proteins or receptors.

Structure and development of antennae in a moth, Manduca sexta

Developmental Biology, 1976
Abstract The antenna of the moth, Manduca sexta , comprises two small basal segments and a long (2 cm) flagellum, which is divided into nearly 80 annuli. The annuli bear cuticular scales and small sensory organs, sensilla. A trachea, a blood vessel, and two nerve trunks run through the lumen of the antenna and into the head. Sensilla are arranged in

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 ...
