Population differentiation and structural variation in the Manduca sexta genome across the United States [PDF]
Many species that are extensively studied in the laboratory are less well characterized in their natural habitat, and laboratory strains represent only a small fraction of the variation in a species’ genome.

Manduca sexta experience high parasitoid pressures in the field but minor fitness costs of consuming plant secondary compounds [PDF]
Plant‐herbivore coevolutionary interactions have led to a range of plant defenses that minimize insect damage and a suite of counter adaptations that allow herbivores to feed on defended plants.

Spatial odor discrimination in the hawkmoth, Manduca sexta (L.) [PDF]
Flying insects track turbulent odor plumes to find mates, food and egg-laying sites. To maintain contact with the plume, insects are thought to adapt their flight control according to the distribution of odor in the plume using the timing of odor onsets ...

Gene expansion in the hawkmoth Manduca sexta drives evolution of food-associated odorant receptors [PDF]
Summary: In insects, odorant receptors (ORs) are required for the detection of most olfactory cues. We investigated the function of a clade of four duplicated ORs in the hawkmoth Manduca sexta and found that these paralogs encode broadly tuned receptors ...

A flight sensory-motor to olfactory processing circuit in the moth Manduca sexta [PDF]
Neural circuits projecting information from motor pathways to sensory pathways are common across sensory domains. These circuits typically modify sensory function as a result of motor pattern activation; this is particularly so in cases where the ...

microRNA390 modulates Nicotiana attenuata's tolerance response to Manduca sexta herbivory [PDF]
miR390 is a highly conserved miRNA in plant lineages known to function in growth and development processes, such as lateral root development, and in responses to salt and metal stress.

Starvation-Induced Changes to the Midgut Proteome and Neuropeptides in Manduca sexta [PDF]
Starvation is a complex physiological state that induces changes in protein expression to ensure survival. The insect midgut is sensitive to changes in dietary content as it is at the forefront of communicating information about incoming nutrients to the

Biomimicry of the Hawk Moth, Manduca sexta (L.), Produces an Improved Flapping-Wing Mechanism
Flapping-wing micro air vehicles (FWMAVs) that mimic the flight capabilities of insects have been sought for decades. Core to the vehicle’s flight capabilities is the mechanism that drives the wings to produce thrust and lift.

The immune signaling pathways of Manduca sexta [PDF]
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

Elastic proteins in the flight muscle of Manduca sexta [PDF]
The flight muscles (DLM1) of the Hawkmoth, Manduca sexta are synchronous, requiring a neural spike for each contraction. Stress/strain curves of skinned DLM1 showed hysteresis indicating the presence of titin-like elastic proteins. Projectin and kettin are titin-like proteins previously identified in Lethocerus and Drosophila flight muscles.
