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...

OBJECTIVE To investigate the larvicidal efficacy of different extracts of Ficus benghalensis L. against Culex quinquefasciatus Say, Aedes aegypti L. and Anopheles stephensi L. (Diptera: Culicidae). MATERIALS AND METHODS Larvicidal efficacy of the crude leaf extracts of Ficus benghalensis with three different solvents like methanol, benzene and acetone was tested against the early second, thir...

Zika virus (ZIKV) has become a threat to global health since the outbreak in Brazil in 2015. Although ZIKV is generally considered an Aedes-transmitted pathogen, new evidence has shown that parts of the virus closely resemble Culex-transmitted viruses. Therefore, it is important to evaluate the competence of Culex species for ZIKV to understand their potential as vectors. In this study, female ...

background: mosquitoes transmit several diseases to human. there are several measures for control of larvae. as part of integrated vector management (ivm) program, the utility of floating layers of polystyrene beads (eps) is a po­ten­tial alternative in habitats of mosquito larva. eps beads prevent oviposition of mosquito as well as killing the im­ma­ture stages by forming a tick layer on the w...

Culex quinquefasciatus (the southern house mosquito) is an important mosquito vector of viruses such as West Nile virus and St. Louis encephalitis virus, as well as of nematodes that cause lymphatic filariasis. C. quinquefasciatus is one species within the Culex pipiens species complex and can be found throughout tropical and temperate climates of the world. The ability of C. quinquefasciatus t...

The effectiveness of four types of mosquito traps at sampling Culex mosquitoes was compared at two north central Florida study sites (a commercial dairy and a swine research unit) with highly eutrophic lagoons that have a history of producing large populations of Culex mosquitoes. Traps evaluated included a John Hock (JH) model 1012 CDC style light trap, JH model 1712 CDC Gravid Trap (GT), and ...

Attraction of Culex quinquefasciatus Say, Culex tarsalis Coquillett, Culex nigripalpus Theobald, and Aedes aegypti (L.) to avian and other host odors was investigated in a dual-port olfactometer. Although attraction to a human arm was high for Ae. aegypti (>80%) and low for all Culex spp. (<25%), all species responded similarly to a chicken (55.3-73.6%). Responses of Ae. aegypti, Cx. quinquefas...

background : within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of annona senegalensis leaf extract and its 4 fractions against anopheles gambiae and culex quinquefasciatus were evaluated in the laboratory conditions. methods : ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while ...
