Vitellogenesis in Manduca sexta [PDF]
Eggs of Manduca sexta contain four well-characterized protein derived from hemolymph: vitellogenin and lipophorin (very high density lipoproteins); microvitellogenin, a 26,000 dalton female-specific protein lacking lipid and carbohydrate, and ...

Host Plant Constancy in Ovipositing Manduca sexta. [PDF]
AbstractMany pollinating insects exhibit flower constancy, i.e. they target flower species they have already experienced and fed from. While the insects might profit from reduced handling costs when revisiting similar flowers, flower constancy, in addition, is of benefit for the plants as it guarantees pollen transfer to conspecifics.

Discovery of a Manduca sexta Allatotropin Antagonist from a Manduca sexta Allatotropin Receptor Homology Model [PDF]
Insect G protein coupled receptors (GPCRs) have important roles in modulating biology, physiology and behavior. They have been identified as candidate targets for next-generation insecticides, yet these targets have been relatively poorly exploited for ...

Storage hexamer utilization in Manduca sexta [PDF]
In preparing for metamorphosis insects store in their hemolymph and fat bodies a major nutrient reserve of 500-kDa hexamerins. At least three hexamerins serve this function in Lepidoptera, including arylphorin (ArH) and two high methionine proteins (M ...

Zinc and Manduca sexta hemocyte functions [PDF]
Two metalloproteases have recently been linked to the immune response in Lepidoptera. In addition, zinc is highly important in many mammalian immune-related functions.

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.

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.

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