Antibacterial hemolymph proteins of Manduca sexta
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1986Exclusion column fractionated immune hemolymph of the M. sexta larva contains five peaks of anti-E. coli activity with molecular weights of greater than 140 kD and approximately 91, 54, 14 and 4 kD, plus one peak of lysozyme activity with a molecular weight of 17 kD.

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).

Protein Expression and Purification, 2003
Manduca diuresin (MD), a 30 amino acid peptide isolated from the tobacco hornworm Manduca sexta, was found to play an important role in the regulation of water and salt balance in the insect. To facilitate studies relating to the function and structure of MD, a synthetic gene encoding MD was assembled and expressed in Escherichia coli.

Serpins from an Insect, Manduca sexta
1997Members 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, 2000The 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, 1981Abstract 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, 2003Cells 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, 2002Recognition 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, 1976Abstract 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
