In mosquitoes, spirochetes were first detected in 1907, when Jaffé reported a spirochete in Culex sp. and named it Spirochaeta culicis (Arch. Protistenkd. 9: 100-107.). Spirochetes were also detected in Anopheles funestus and A. maculipennis (Sinton J.A., Shute P.G. 1939: J. Trop. Med. Hyg. 42: 125-126) and in the salivary glands of Anopheles gambiae (Masseguin A., Palinacci A. 1954: Bull. Soc....

Mosquitoes in the Culex pipiens complex are important vectors of several disease-causing pathogens, including West Nile virus. In North America, the complex consists of Cx. pipiens pipiens form pipiens, Cx. pipiens pipiens form molestus, Cx. pipiens quinquefasciatus, and their hybrids that exhibit substantial diversity in physiology, behavior, and geographic range. Hybridization among these mos...

The feeding behavior of vectors influences the likelihood of pathogen invasion and the exposure of humans to vector-borne zoonotic pathogens. We used multilocus microsatellite genetic typing of an introduced mosquito vector and DNA sequencing of mosquito blood meals to determine the impact of hybrid ancestry on feeding behavior and the emergence of West Nile virus (WNV). The probability of ance...

The chemical composition of the essential oils of the wild growing plants of Greek S. spinosa L., S. parnassica subsp. parnassica Heldr.& Sart ex Boiss., S. thymbra and S. montana were determined by GC and GC/MS analysis. The larvicidal activities of the essential oils were assayed against Culex pipiens biotype molestus. The analytical data indicated that various monoterpene hydrocarbons and ph...
