Infectious diseases increasingly play a role in the decline of wildlife populations. Vector-borne diseases, in particular, have been implicated in mass mortality events and localized population declines are threatening some species with extinction. Transmission patterns for vector-borne diseases are influenced by the spatial distribution of vectors and are therefore not uniform across the lands...

BACKGROUND & OBJECTIVES Taxonomic status of Culex pipiens is well-known as many years with such a wide variety of morphological and biological characteristics. These changes have been the subject of extensive investigation by many researchers. There are a little information about the morphology and molecular data of Cx. pipiens complex in Iran. The taxonomic status of the complex is very import...

The purpose of this study was for the first time to establish phylogenetic hypotheses among Culex (Culex) species from Argentina, and to evaluate the relationships of this subgenus with subgenera Phenacomyia and Phytotelmatomyia. We employed maximum parsimony to analyse morphological characters derived from the morphology of the adult, pupal and larval stages. More than 30 figures, including ph...

The role of lactic acid was evaluated for attraction of Culex nigripalpus, Culex quinquefasciatus, Culex tarsalis, and Aedes aegypti in the laboratory using a dual-port olfactometer. When lactic acid was combined with chicken odor, attraction was increased for Cx. quinquefasciatus compared to chicken odor alone but not for Cx. nigripalpus, Cx. tarsalis, and Ae. aegypti. Lactic acid combined wit...

The species composition and population dynamics of adult mosquitoes in a wetland near Iuka, MS, were analyzed over a 6-yr period (1997Ð2002) and reverse transcription-polymerase chain reaction(PCR)detection ratesof arbovirusesdeterminedduringÞveof thoseyears.Bloodmeals of three likely vector species were identiÞed using a PCR-based method that allows identiÞcation of the host to species. Culex ...

Most records of Culex and Lutzia from Thailand refer to nocturnal feeding on mammals, eg, humans, cows, and dogs. The periodicity of nocturnal feeding varies greatly depending on the species. Culex (Cux.) quinquefasciatus, for example, are fairly abundant in urban areas throughout the year and are commonly found resting during the day in shade outdoors, and on walls, dark corners, in cabinets, ...

Culex pipiens quinquefasciatus Say and Culex pipiens pipiens Linnaeus are sibling species incriminated as important vectors of emerging and re-emerging infectious diseases worldwide. The two forms differ little morphologically and are differentiated mainly based upon ecological, behavioural, physiological and genetic traits. Within the North American zone of sympatry, populations of Cx. p. quin...

Five trapping methods were compared for monitoring potential vectors of the West Nile virus in four areas in the Camargue Plain of France: carbon dioxide traps, bird-baited traps, gravid traps, resting boxes, and human landing catches. A total of 73,721 specimens, representing 14 species, was trapped in 2006. Results showed significant differences in species and abundance between the type of tr...

An Aedes aegypti-specific, fluorogenic probe hydrolysis (Taq-Man), polymerase chain reaction assay was developed for real-time screening using a field-deployable thermocycler. Laboratory-based testing of A. aegypti, A. aegypti (Trinidad strain), Culex pipiens, Culex quinquefasciatus, Anopheles stephensi, and Ochlerotatus taeniorhynchus individual adult mosquitoes and mixed pools (n = 10) demons...

Zika virus is a newly emergent mosquito-borne flavivirus that has caused recent large outbreaks in the new world, leading to dramatic increases in serious disease pathology including Guillain-Barre syndrome, newborn microcephaly, and infant brain damage. Although Aedes mosquitoes are thought to be the primary mosquito species driving infection, the virus has been isolated from dozens of mosquit...
