Population differentiation and structural variation in the Manduca sexta genome across the United States [PDF]
G3: Genes, Genomes, Genetics, 2022 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]
Ecology and Evolution, 2021 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.

Biomimicry of the Hawk Moth, Manduca sexta (L.), Produces an Improved Flapping-Wing Mechanism [PDF]
Biomimetics, 2020 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.

Spatial odor discrimination in the hawkmoth, Manduca sexta (L.) [PDF]
Biology Open, 2021 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]
iScienceSummary: 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 ...

Complete Metamorphosis in Manduca sexta Involves Specific Changes in DNA Methylation Patterns
Frontiers in Ecology and Evolution, 2021 The transition between morphologically distinct phenotypes during complete metamorphosis in holometabolous insects is accompanied by fundamental transcriptional reprogramming.

microRNA390 modulates Nicotiana attenuata's tolerance response to Manduca sexta herbivory [PDF]
Plant Direct, 2021 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]
InsectsStarvation 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

Sex-specific odorant receptors of the tobacco hornworm Manduca sexta
Frontiers in Cellular Neuroscience, 2010 As odor information plays a vital role in the life of moths, their olfactory sense has evolved into a highly specific and sensitive apparatus relevant to reproduction and survival.

Frontiers in Ecology and Evolution, 2016 Olfactory systems evolved to detect and identify volatile chemical cues, in many cases across great distances. However, the precision of copulatory and oviposition behaviors suggest that they may be guided by olfactory cues detected by sensory systems ...
