Transcription profiling and regulation of fat metabolism genes in diapausing adults of the mosquito Culex pipiens.
Culex pipiens, the mosquito that vectors West Nile virus in North America, overwinters in an adult diapause (dormancy) that is programmed by the short day length and low temperatures of autumn. In response to these environmental signals, females cease feeding on blood and instead seek sources of nectar used to generate the huge lipid reserves required for winter survival. To identify regulatory...
متن کاملSolid-state NMR reveals differential carbohydrate utilization in diapausing Culex pipiens
Culex pipiens is the mosquito that vectors West Nile Virus and other human-pathogenic flavivruses in North America. In response to shortened day length and lower temperatures, female Cx. pipiense prepares for the diapause by actively feeding on carbohydrates to increase the biosynthesis of glycogen and lipid to store energy for overwintering. The effect of feeding different carbohydrates on gly...
متن کاملSeasonal gene expression kinetics between diapause phases in Drosophila virilis group species and overwintering differences between diapausing and non-diapausing females
Most northern insect species experience a period of developmental arrest, diapause, which enables them to survive over the winter and postpone reproduction until favorable conditions. We studied the timing of reproductive diapause and its long-term effects on the cold tolerance of Drosophila montana, D. littoralis and D. ezoana females in seasonally varying environmental conditions. At the same...
متن کاملTranscriptional Differences between Diapausing and Non-Diapausing D. montana Females Reared under the Same Photoperiod and Temperature
BACKGROUND A wide range of insects living at higher latitudes enter diapause at the end of the warm season, which increases their chances of survival through harsh winter conditions. In this study we used RNA sequencing to identify genes involved in adult reproductive diapause in a northern fly species, Drosophila montana. Both diapausing and non-diapausing flies were reared under a critical da...
متن کاملComparative studies of oxidative enzyme systems in epidermis and fat body of diapausing and non-diapausing silkmoths.
The activities of four oxidative enzyme systems, including NADH oxidase, succinate-cytochrome c reductase, NADH-cytochrome c reductase, and cytochrome c oxidase, were compared in mitochondrial-microsomal preparations from wing epidermis and fat body of diapausing Samia Cynthia pupae, presumptively non-diapausing S. Cynthia ricini pupae which were caused to diapause by removal of the brain, and ...
