The best way to control mosquito borne diseases is to control the mosquito population. The present study was executed to evaluate the mosquito larvicidal activity of Nicotiana plumbaginifolia leaves against malarial vector Anopheles stephensi.Crude extracts and three different solvent extracts were bio-assayed against An. stephensi larvae. LC50 and LC90 values were determined appropriately. Qua...

Malaria is considered a major health problem in Iran. There are different methods for vector control. In this study we tested the larvicidal effects of some Iranian plants. The methanolic extracts of 11 plants were prepared with percolation method. The larvicidal activities of them against malaria vector, Anopheles stephensi were studied using World Health Organization standard method. All LC50...

A field trial was conducted in Block F of the Moti Bagh area of New Delhi Municipal Committee to demonstrate composite control of Anopheles stephensi and Aedes aegypti by spraying deltamethrin at 100 mg/m2 on window and door curtains of habitations. Results revealed drastic reduction (87.9-93.7%, P < 0.05) of target species in the experimental area. The impact of deltamethrin-treated curtains w...

BACKGROUND Malaria is still a health problem in Iran. There are several vector control activities, including Indoor Residual spraying, using insecticide treated nets and larviciding including Temephos. In addition nuisance mosquitos are prevalent in the urban areas. So that evaluation of this species to larvicide will provide a clue for management of vector control activities. METHODS Two mos...

The 3-hydroxykynurenine transaminase (3-HKT) gene plays a vital role in the development of malaria parasites by participating in the synthesis of xanthurenic acid, which is involved in the exflagellation of microgametocytes in the midgut of malaria vector species. The 3-HKT enzyme is involved in the tryptophan metabolism of Anophelines. The gene had been studied in the important global malaria ...

The efficacy of synthetic pyrethroid-impregnated fabrics was evaluated against Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus, under laboratory conditions. Results revealed that delta-methrin was significantly superior in comparison to lambdacyhalothrin and cyfluthrin. Results of bioassay tests revealed that deltamethrin was 1.5 and 1.9 times more effective than lambdacyhalothri...

Bioactive molecules of plant origin play a significant role as defensive agents in different insect species. Chemical compounds medicinal plants have been an exciting alternative to standard methods controlling mosquito larvae. The present study evaluates the solvent extracts D. hamiltonii for toxicity against three Bioassay revealed that effect methanol increased larval mortality with increasi...

Very recently, the Asian malaria vector (Anopheles stephensi) was stably transinfected with the wAlbB strain of Wolbachia, inducing refractoriness to the human malaria parasite Plasmodium falciparum. However, conditions in the field can differ substantially from those in the laboratory. We use the rodent malaria P. yoelii, and somatically transinfected An. stephensi as a model system to investi...
