Genetic differences between Culex pipiens f. molestus and Culex pipiens pipiens (Diptera: Culicidae) in New York.
The definition and phylogenetic placement of the autogenous molestus form of Culex pipiens has puzzled entomologists for decades. We identified genetic differences between Cx. p. pipiens (L.) and Cx. pipiens f. molestus Forskål in the SH60 fragment described previously. Single-strand conformation polymorphism analysis, cloning, and sequencing of this fragment demonstrated high polymorphism with...
متن کاملFirst Nationwide Surveillance of Culex pipiens Complex and Culex torrentium Mosquitoes Demonstrated the Presence of Culex pipiens Biotype pipiens/molestus Hybrids in Germany
Mosquitoes and other arthropods may transmit medically important pathogens, in particular viruses such as West Nile virus. The presence of suitable hosts and competent vectors for those zoonotic viruses is essential for an enzootic transmission, which is a prerequisite for epidemics. To establish reliable risk projections, it is an urgent need for an exact identification of mosquito species, wh...

متن کاملPyrethroid tolerance in Culex pipiens pipiens var molestus from Marin County, California.
In May 2001 a sample of Culex pipiens pipiens variety molestus Forskål from Marin County, California, collected as larvae and reared to adults, was found to show reduced resmethrin and permethrin knock-down responses in bottle bioassays relative to a standard susceptible Cx. pipiens quinquefasciatus Say colony (CQ1). Larval susceptibility tests, using CQ1 as standard susceptible, indicated that...
متن کاملResponse of the mosquito Culex pipiens molestus in the Amman area of Jordan to certain insecticides.
The response of adult females of the mosquito Culex pipiens molestus to six insecticides was evaluated. Adults were collected from two locations in the Amman area from May to October 1983. The F1 generation was exposed to paper-impregnated insecticides using WHO test kits. At both locations, the most toxic insecticides were permethrin, propoxur and ferpropathrin. Malathion, dieldrin and DDT wer...
