Epithelial differentiation in Drosophila pupae

Developmental Genetics, 1989
AbstractThe construction of cell hairs on the wings in developing pupae of Drosophila provides a unique system for studies of the regulation of differentiation in the absence of cell division. Early steps in hair construction are the extrusion of cell hairs and the deposition of the external impervious layer called “cuticulin.” Some properties of six ...

Effect of Mechanical Impacts on Pupae of the Cabbage Looper: Survival of Pupae and Condition of Imago12

Journal of Economic Entomology, 1972
Pupae of Trichoplusia ni (Hubner) were subjected to impacts equivalent to a free fall of 6.8, 30.5, and 67 cm to their anterior, caudal, lateral, dorsal, and ventral surfaces. Pupal deaths and adult deformities increased with increasing impact forces and were greatest when pupae were struck (simulated landing) on the anterior surface. Since older pupae

The Origin and Evolution of the Pupa

The Canadian Entomologist, 1958
There have been several speculations as to the origin and significance of the pupa. One that has had considerable vogue is based on the interpretation, by Lubbock (1883), Berlese (1913) and others, of the larva as a free-living embryo prematurely hatched before it has attained the form characteristic of the adult. A nymph, according to this theory, has

Haemolymph ecdysone concentrations in Hyalophora cecropia pupae, dauer pupae and adults

Journal of Insect Physiology, 1979
Abstract Haemolymph ecdysone concentrations were determined by radioimmunoassay in diapausing pupae, pharate adults, adults, and chilled dauer pupae. The concentration in diapausing pupae after 6 months chilling (5.35 pg/μl) increased dramatically after 3 days at 27°C (>200 pg/μl) and then decreased to low levels in adult females (1.63 pg/μl).
