We cloned the gene that encodes prothoracicotropic hormone (PTTH) in the northern house mosquito, Culex pipiens, investigated its expression profile in short-day (diapause-destined) and long-day (nondiapause-destined) individuals from the fourth instar larval stage through two-months of adulthood, as well as after a blood meal.The deduced Cupip-PTTH amino acid sequence contains seven Cited by: 4.
Adult females of the mosquito Culex pipiens entering diapause increase sugar water ingestion and reduce evaporative water loss, but how these attributes of the diapause program impact activity of the renal excretory system remains unknown. Here we compared the renal excretory capacity of diapausing and non-diapausing females, as well as the molecular expression of aquaporin (AQP) genes that Cited by: 4.
Diapause-specific gene expression in the northern house mosquito, Culex pipiens L., identified by suppressive subtractive hybridization. The results presented here provide some first clues about the molecular events that characterize the adult diapause of Cx. pipiens. We have identified 40 genes by suppressive subtractive hybridization and Cited by: 132.
Jan 23, 2015 · Abstract. Females of the northern house mosquito, Culex pipiens L., are capable of entering an adult overwintering diapause characterized by arrested ovarian development, enhanced stress tolerance, and elevated lipid stores. In contrast, the southern house mosquito, Culex quinquefasciatus Say, lacks this capacity and is therefore unable to survive the harsh winters found in Cited by: 6.
Nov 01, 2005 · Culex pipiens (L.), a temperate-zone mosquito that vectors West Nile virus, enters an overwintering dormancy (diapause) in response to short day length and low temperatures received in the fourth larval instar and early pupal stage (1–3). Only adult females enter diapause (4, 5), and they first Cited by: 148.
