In insects, ABC transporters have been shown to contribute to defence/resistance to insecticides by reducing toxic concentrations in cells/tissues. Despite the extensive studies about this detoxifying mechanism, the temporal patterns of ABC transporter activation have been poorly investigated. Using the malaria vector Anopheles stephensi as a study system, we investigated the expression profile...

Malaria is one of the most important infectious diseases in the world, and it has many economic and social impacts on populations, especially in poor countries. Transmission-blocking vaccines (TBVs) are valuable tools for malaria eradication. A study on Anopheles gambiae revealed that polyclonal antibodies to carboxypeptidase B1 of A. gambiae can block sexual parasite development in the mosquit...

The crude extract of mangrove plant Rhizophora mucronata was prepared in this present work. The extract was testified for its anti-mosquito larvicidal property against two species of mosquito viz: Anopheles stephensi and Aedes aegypti. The 48 hours exposure of various dilutions of 100, 200, 300, 400, 500 ppm were given to the III to IV instar larval population. Percentage mortality data was ana...

BACKGROUND Anopheles mosquitoes are an important group of arthropods due to their role in transmission of malaria. The present study was conducted for determination of susceptibility status of Anopheles stephensi to different imagicides collected from malarious area in Chabahar city, Iran. METHODS In the present study seven insecticides including: DDT 4%, lambdacyhalothrin 0.05%, deltamethrin...

Leaves of Artemisia annua linn. and Azadirachta indica were extracted in petroleum ether and hexane respectively by different methods of extraction i.e. cold extraction, reflux extraction and soxhlet extraction. The crude extract obtained was tested against third instar larvae of Anopheles stephensi. On comparison of larval mortality of crude extract obtained by these three methods, both soxhle...

Microbe mediated synthesis of silver nanoparticles (AgNPs) constitutes a reliable, eco-friendly approach ameliorating green-chemistry principles. In this study, stable silver nanoparticles were synthesized by exposing aqueous silver ions to extracellular exudates of B. subtilis A1 under optimized laboratory conditions. The synthesized nanoparticles were characterized by spectroscopic and micros...

Efficacy of the methanol extracts from fruits without seeds, whole yellow ripe fruits and seeds of the plant Solanum xanthocarpum was evaluated against larvae of Anopheles culicifacies, Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus, the important vector mosquitoes prevalent in the arid region. Experiments were carried out on late 3rd or early 4th instar larvae of these mosquitoe...

Abstract Insecticides kill mosquitoes but damage other animals including humans. Eco-friendly metal nanoparticles may be a plant-based pesticide for vector control. Here, the copper (Cu NPs) synthesized from Nepeta cataria leaves have been investigated their antibacterial and larvicidal properties. Fourier transforms infrared spectroscopy demonstrated that biochemicals reduced stabilized by shi...

background: there is very little information about the mosquito fauna of qom province, central iran. by now only three species; anopheles claviger , an. multicolor , and an. superpictus have been reported in the province. to study mosquito fauna and providing a primary checklist, an investigation was carried out on a collection of mosquitoes in this province. methods: to study the mosquito (dip...
