BACKGROUND Anopheles stephensi is a sub-tropical species and has been considered as one of the most important vector of human malaria throughout the Middle East and South Asian region including the malarious areas of southern Iran. Current reports confirmed An. stephensi resistance to temephos in Oman and India. However, there is no comprehensive research on mechanisms of temephos resistance in...

We previously selected a line of the malaria vector mosquito Anopheles stephensi refractory (resistant) to the human malaria parasite Plasmodium falciparum, using in vitro infections with P. falciparum gametocytes. This report presents data on the genetic background of refractoriness. The results of F1-crosses and backcrosses show that refractoriness to P. falciparum in our A. stephensi line is...

Anopheles stephensi is the main urban mosquito vector of malaria in the Indian subcontinent, and belongs to the same subgenus as Anopheles gambiae, the main malaria vector in Africa. Recently the genome and proteome sets of An. gambiae have been described, as well as several protein sequences expressed in its salivary glands, some of which had their expression confirmed by amino terminal sequen...

The leaf extract of Solanum trilobatum (Solanaceae) was tested under laboratory conditions for oviposition deterrent and skin repellent activities against the adult mosquito Anopheles stephensi. Concentrations of 0.01, 0.025, 0.05, 0.075 and 0.1% reduced egg laying by gravid females from 18 to 99% compared to ethanol-treated controls. In skin repellent tests, concentrations of 0.001, 0.005, 0.0...

background : one of the best ways to control the malaria disease and to be protected human against anopheles mos­quito biting is the use of repellents. throughout repellents, herbal ones may be an appropriate and safe source for protection. methods : chemical constituents of achillea vermiculata and satoreja hortensis were determined by using gas chromatography-mass spectrometry. efficacy and t...

background: indoor residual spraying (irs) is functioned as national interventions against malaria in southeastern foci of iran and deltamethrin wp one of the insecticides have been used since past decade. in this study, the residual activity of the wettable granule (wg) was studied on different surfaces in hut scale trial against anopheles stephensi   in iranshahr district, southeastern iran. ...

background: many microorganisms in midgut of mosquito challenge with their host and also other pathogens pre­sent in midgut. the aim of this study was presence of non-pathogens microorganisms like fungal flora which may be cru­cial on interaction between vectors and pathogens. } methods: different populations of anopheles stephensi were reared in insectary and objected to determine fungal flora...

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...

background and objectives: malaria is a remarkable cause of death in the world. several ways are used by researchers to control or to decrease the detrimental effects of the disease, in which natural insecticides with less malaria vectors resistance and lower environmental damages are considered in last decades.the objective of this study was to assess the larvicidal activity of the whole flowe...

The Indian islands of Lakshadweep in the Arabian sea are known to be endemic for bancroftian filariasis. However, malaria endemicity was reported to be associated with the invasion of vector species Anopheles tessellatus from Maldives. Indigenous transmission of malaria was recorded during 1972. Thereafter the National Anti-Malaria Programme (NAMP) brought these islands under DDT spray. Since 1...
