This study was carried out to know about the various species of mosquito in Surguja district during June 2021 May 2022. Larvae and adult mosquitoes were also studied currently. In this study, 15 belonging a total 3 genera found which are as follows Aedes, Culex and, Anopheles (64.39%) highly hegemonic followed by (25.07%) Aedes (10.52%) respectively. albopictus, Culex. Quinquefasciatus complete...

BACKGROUND Dar es Salaam has an extensive drain network, mostly with inadequate water flow, blocked by waste, causing flooding after rainfall. The presence of Anopheles and Culex larvae is common, which is likely to impact the transmission of lymphatic filariasis and malaria by the resulting adult mosquito populations. However, the importance of drains as larval habitats remains unknown. METH...

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...

Background. Outbreaks of the West Nile virus infection were reported in Morocco in 1996, 2003, and 2010. Culex pipiens was strongly suspected as the vector responsible for transmission. In the North center of Morocco, this species has developed resistance to synthetic insecticides. There is an urgent need to find alternatives to the insecticides as natural biocides. Objective. In this work, the...

BACKGROUND There are unorganized, published documents about the ecology of mosquitoes (Diptera: Culicidae) in northeastern part of Iran. The purpose of this study was to determine the distribution and characteristics of larval habitats of Culicidae in Kalaleh County. METHODS Larvae were collected using dipping method and adults by human landing catch technique during April-October, 2012. Larv...

Resistance to insecticides has persuaded researchers to find new methods to control Culex quinquefasciatus proliferation. Plants may be a source of alternative agents for mosquito control due to ever-growing insecticide resistance in mosquito vectors and environmental imbalance caused by synthetic insecticides. The present study was intended to study the larvicidal activity of selected Cyathea ...

Alphavirus transducing systems (ATSs) are alphavirus-based tools for expressing genes in insects. Here we describe an ATS (5'dsMRE16ic) based entirely on Sindbis MRE16 virus. GFP expression was used to characterize alimentary tract infections and dissemination in three Culicine and two Lepidopteran species. Following per os infection, 5'dsMRE16ic-EGFP efficiently infected Aedes aegypti and Cule...

in order to study the mosquito fauna of iran, and to prepare the temporal as well as the spatial distribution of the iranian mosquitoes, a comprehensive study has started since 1981. in this program in which more than 60.000 mosquito larvae, from different breeding sites has been studied, 15 species of culex are reported. these are;cx. arbieeni, cx. bitaeniorhynchus, cx. deserticola, cx. horten...

Sixteen Escherichia coli clones were assayed against susceptible and Bacillus thuringiensis-resistant Culex quinquefasciatus larvae. The clones expressed different combinations of four genes from Bacillus thuringiensis ssp. israelensis; three genes encoded mosquitocidal toxins (Cry11Aa, Cry4Aa and Cyt1Aa) and the fourth encoded an accessory protein (P20). The cross-resistance spectra of the mos...

Laboratory bioassay of the essential oil extracted from an indigenous plant, Ipomoea cairica, commonly known as 'Railway creeper', was carried out against the larvae of four vector species of mosquitoes in order to evaluate its mosquito larvicidal effect. Bioassay test revealed that the essential oil of the plant possess remarkable larvicidal properties as it could induce 100% mortality in the ...
