The immune signaling pathways of Manduca sexta [PDF]

Insect Biochemistry and Molecular Biology, 2015
Signal transduction pathways and their coordination are critically important for proper functioning of animal immune systems. Our knowledge of the constituents of the intracellular signaling network in insects mainly comes from genetic analyses in Drosophila melanogaster. To facilitate future studies of similar systems in the tobacco hornworm and other

Influence of Temperature on the Physiology and Virulence of the Insect Pathogen Serratia sp. Strain SCBI [PDF]

, 2012
The physiology of a newly recognized Serratia species, termed South African Caenorhabditis briggsae Isolate (SCBI), which is both a nematode mutualist and an insect pathogen, was investigated and compared to that of Serratia marcescens Db11, a broad-host-

The role of TcdB and TccC subunits in secretion of the photorhabdus Tcd toxin complex [PDF]

, 2013
The Toxin Complex (TC) is a large multi-subunit toxin encoded by a range of bacterial pathogens. The best-characterized examples are from the insect pathogens Photorhabdus, Xenorhabdus and Yersinia.

High-throughput screening of caterpillars as a platform to study host–microbe interactions and enteric immunity

Nature Communications, 2022
Here, combining diagnostic imaging modalities and in vivo assays, Windfelder and colleagues established tobacco hornworm larvae Manduca sexta as an alternative high-throughput platform to study the innate immunity of the gut and host-pathogen ...

Unique neural coding of crucial versus irrelevant plant odors in a hawkmoth

eLife, 2022
The sense of smell is pivotal for nocturnal moths to locate feeding and oviposition sites. However, these crucial resources are often rare and their bouquets are intermingled with volatiles emanating from surrounding ‘background’ plants.

Presence of unsaturated sphingomyelins and changes in their composition during the life cycle of the moth Manduca sexta

Journal of Lipid Research, 2004
NMR and electrospray ionization tandem mass spectrometry were used to show for the first time the presence of sphingomyelins in extracts of the tobacco hornworm Manduca sexta (Lepidoptera).

Learning of multi-modal stimuli in hawkmoths. [PDF]

PLoS ONE, 2013
The hawkmoth, Manduca sexta, uses both colour and odour to find flowers when foraging for nectar. In the present study we investigated how vision and olfaction interact during learning.

Chemiluminescent Tags for Tracking Insect Movement in Darkness: Application to Moth Photo-Orientation [PDF]

, 2017
The flight tracks of Manduca sexta (Lepidoptera: Sphingidae) flying toward a 5 watt incandescent light bulb were recorded under low light conditions with the aid of a camera-mounted photomultiplier and a glowing marker technique.

Dynamical transitions in a pollination--herbivory interaction [PDF]

, 2015
Plant-pollinator associations are often seen as purely mutualistic, while in reality they can be more complex. Indeed they may also display a diverse array of antagonistic interactions, such as competition and victim--exploiter interactions.

The main triglyceride-lipase from the insect fat body is an active phospholipase A1: identification and characterization

Journal of Lipid Research, 2006
The main triglyceride-lipase (TG-lipase) from the fat body of Manduca sexta has been identified as the homolog of Drosophila melanogaster CG8552. This protein is conserved among insects and also shares significant sequence similarity with vertebrate ...
