Population genetics of the mosquito Culex pipiens pallens reveals sex-linked asymmetric introgression by Culex quinquefasciatus.
The Culex pipiens complex in Asia includes a temperate subspecies, Culex pipiens pallens, of uncertain taxonomic status. The shape of the male genitalia suggests it is a hybrid between Cx. pipiens and Cx. quinquefasciatus. We studied populations of Cx. p. pallens in Japan, Korea, and China and compared them to local populations of Cx. quinquefasciatus and Cx. p. pipiens. We examined variation i...
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...
متن کاملIs the Horaana strain of the Culex pipiens group Culex pipiens pallens?
The validity of the Horaana strain of the Culex pipiens group as Cx. pipiens pallens was studied. Judging from the fourth instar characters and morphology of the adult male genitalia, this laboratory strain is now out of the range of ordinary Cx.p. pallens in Japan, and must be identified as Cx. p. quinquefasciatus.
متن کاملDiversification of Wolbachia endosymbiont in the Culex pipiens mosquito.
The α-proteobacteria Wolbachia are among the most common intracellular bacteria and have recently emerged as important drivers of arthropod biology. Wolbachia commonly act as reproductive parasites in arthropods by inducing cytoplasmic incompatibility (CI), a type of conditional sterility between hosts harboring incompatible infections. In this study, we examined the evolutionary histories of W...
متن کاملPopulation genetics of insecticide resistance in the mosquito Culex pipiens
Thirty years of control of the mosquito Culex pipiens using organophosphate insecticides (OP) has selected for OP-resistance alleles on a world-wide scale. As reviewed here, studies at the levels of gene and population allow identification of the main forces driving this process of adaptation. Three loci are involved in OP-resistance in C. pipiens. For two of these, adaptive mutations were foun...
