Segregation of cytoplasmic incompatibility properties in Culex pipiens fatigans.
Maternally inherited variants, which arose within a laboratory colony of Culex pipiens fatigans, have been studied by rearing cultures from single egg rafts. Segregation, i.e, variation of cytoplasmic incompatibility properties between the male progeny of individual females, was demonstrated. Also, from the daughters of individual females, sub-lines were derived within which all the males showe...
متن کاملCharacterization of phospholipase B of Culex pipiens fatigans.
Phospholipase B has been found in the mosquito Culex pipiens fatigans, and some of its properties have been studied. The enzyme had a high optimum temperature (45 degrees C) and broad alkaline pH optimum (8-9). It was inactive toward diacylphospholipids, and hydrolyzed lysolecithin at a higher rate than lysophosphatidyl ethanolamine. The enzyme was heat labile, but lysolecithin protected it aga...
متن کاملPCR-based identification of Culex pipiens complex collected in Japan.
The Culex pipiens complex consists of vector mosquitoes that transmit important human pathogens. In this study we established a simplified method to distinguish three members of the Cx. pipiens complex, Cx. p. pallens Coquillet, Cx. p. form molestus Forskal, and Cx. quinquefasciatus Say, collected in Japan. Sequence analysis of the Drosophila Ace-orthologous acetylcholinesterase (Ace) gene (668...
متن کاملEmerging vectors in the Culex pipiens complex.
In the Old World, some mosquitoes in the Culex pipiens complex are excellent enzootic vectors of West Nile virus, circulating the virus among birds, whereas others bite mainly humans and other mammals. Here we show that, in northern Europe, such forms differing in behavior and physiology have unique microsatellite fingerprints with no evidence of gene flow between them, as would be expected fro...
متن کاملInsemination rates of hybrids between Culex pipiens pipiens and Culex pipiens quinquefasciatus or Culex pipiens pallens at high temperature.
Females of Culex pipiens pallens are rarely inseminated at temperatures above 30 degrees C. Insemination and egg-hatching rates (F2) were examined in females of hybrids (F1) between Culex pipiens pipiens and Culex pipiens quinquefasciatus at 25 degrees C and 30 degrees C to examine temperature-dependent reproductive activity. Insemination rates were very high in hybrid females (F1) at 25 degree...
