Susceptibility to Organophosphates in Culex quinquefasciatus from Colombia

Journal of the American Mosquito Control Association, 2022
ABSTRACT Susceptibility to organophosphates was evaluated in 2 populations of Culex quinquefasciatus from the department of Atlantico, Colombia. Bioassays for temephos, malathion, and pirimiphos-methyl were performed with 3rd-stage larvae and adult females of Cx. quinquefasciatus from the municipalities of Soledad and Puerto Colombia, following

Vitellogenin genes are transcribed in Culex quinquefasciatus ovary

Memórias do Instituto Oswaldo Cruz, 2023
Culex quinquefasciatus, a cosmopolitan, domestic, and highly anthropophilic mosquito, is a vector of pathogenic arboviruses such as West Nile virus and Rift Valley virus, as well as lymphatic filariasis. The current knowledge on its reproductive physiology regarding vitellogenin expression in different tissues is still limited.In this study, we ...

Culex quinquefasciatus vitellogenesis: morphological and biochemical aspects [PDF]

Memórias do Instituto Oswaldo Cruz, 2010
The vitellogenic process in Culex quinquefasciatus, which is triggered by a blood meal, involves the synthesis, distribution and storage of the nutrients necessary for embryo development. The fat body of an adult female Cx. quinquefasciatus revealed two cell types: large trophocytes and small, eosinophilic, "oenocyte-like" cells, which show no ...

Impact of Bifenthrin on Honeybees and Culex quinquefasciatus

Journal of the American Mosquito Control Association, 2010
The impact of bifenthrin on honeybees, Apis mellifera (Hymenoptera: Apidae) was evaluated in both laboratory and semifield assays. Ten serial dilutions of bifenthrin and an acetone control using the bottle bioassay protocol were used in the laboratory to determine killing time after 15-, 30-, and 60-min honeybee exposure.

Insecticide resistance status in Culex quinquefasciatus in Benin [PDF]

Parasites & Vectors, 2015
Culex quinquefasciatus, an arboviral and filarial vector, is present year round in several cities of the Republic of Benin. There is more information on the resistance status to malaria vectors compared to Culicines. It is therefore unfortunate that the international focus is on Anopheles control and not so much done against Cx.

Effectivity Test of Tobacco Leaf (nicotiana tabacum l.) 96% Ethanol Extract on Culex Quinquefasciatus Larvae Mortality

Saintika Medika, 2020
Culex quinquefasciatus acts as a vector for Filariasis disease. The transmission of this disease can be prevented by cutting the life cycle of these mosquitoes at the larvae phase. Tobacco leaf contains an alkaloid, flavonoid, essential oil, saponin, and
