The physiology of insect diapause
WebbDescription. Chrysolina quadrigemina is a member of the Chrysomelidae, the same insect family that contains the Colorado potato beetle. Its shape and habits are similar to those of this common and destructive pest of solanaceaous plants. When disturbed, Chrysolina spp. beetles will drop from the plant and "play dead" on the soil. Webb10 apr. 2024 · Diapause for female Northern house mosquitoes (Culex pipiens) is not quite a winter slumber, but rather a period of dormancy when the insects live in caves, culverts, sheds and other semi-protected locations. Prior to winter's arrival, mosquitoes convert sugary sources, such as plant nectar, into fat, the researchers said.

We measured transcriptomic changes during larval diapause in the Asian longhorned beetle, Anoplophora glabripennis (Coleoptera: Cerambycidae) . WebbDr. Denlinger’s research focuses on the molecular physiology of insect development, especially the mechanisms used by insects to enter dormancy (diapause) to survive adverse seasons such as winter or tropical dry seasons.

The conception and naming of the phases is unsettled and, sometimes, ambiguous in the literature.
