In China, the prevention and control of Zika virus disease has been a public health threat since the first imported case was reported in February 2016. To determine the vector competence of potential vector mosquito species, we experimentally infected Aedes aegypti, Ae. albopictus, and Culex quinquefasciatus mosquitoes and determined infection rates, dissemination rates, and transmission rates....

Field studies were conducted to determine the mosquito species richness in the urban area of Greater Puntarenas in Costa Rica. Two cross-sectional entomological surveys were performed in seven localities of Puntarenas: one survey was performed during the wet season and the other during the dry season. The sections evaluated were determined by applying a stratified cluster sampling method using ...

Background Culex quinquefasciatus (Diptera: Culicidae) is an important vector for many human diseases. The aim of this study was to evaluate the susceptibility level of larval and adult stages of Cu. quinquefasciatus to different groups of WHO recommended insecticides for vector control. Methods Larval stages of the Culex mosquitoes were collected from their natural habitats in Rafsanjan Coun...

Abstract Anopheles stephensi mosquitoes share urban breeding sites with Aedes aegypti and Culex quinquefasciatus in the Republic of Djibouti. We present evidence that A. might be responsible for an increase malaria incidence this country. also document resistance Plasmodium falciparum to dihydroartemisinin/piperaquine.

Abstract The subgenus Culex L. includes species involved in summer–autumn arbovirus transmission but studies during winter are scarce temperate Argentina. Female specimens were collected host-seeking at dry-ice-baited traps autumn–winter–spring two sites Córdoba City 2016 and 2017. morphologically identified dissected to determine the follicular developmental stage (gonotrophic activity). Femal...

The transmission of vector-borne pathogens is greatly influenced by the ecology of their vector, which is in turn shaped by genetic ancestry, the environment, and the hosts that are fed on. One group of vectors, the mosquitoes in the Culex pipiens complex, play key roles in the transmission of a range of pathogens including several viruses such as West Nile and St. Louis encephalitis viruses, a...

BACKGROUND Culex pipiens molestus was first reported in Shanghai in 2010. The population structures and seasonal distributions of Culex pipiens subspecies C. p. molestus, Culex pipiens pallens, and Culex pipiens quinquefasciatus are not well known. METHODS From late February to November 2013, we conducted daily field surveillance of mosquitoes at eight sites at two green lands and three resid...

Background: The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to ...
