Mosquitoes are the carriers of severe and well-known illnesses such as malaria, arboviral encephalitis, dengue, chikungunya and yellow fever, which cause significant morbidity and mortality in humans and domestic animals around the world. Entomopathogenic fungal metabolites act as a mosquito control agent and are potential alternatives to chemical control because they can be innovative and more...

anopheles stephensi is one of the main vectors of malaria in the world including south of iran. three geographical populations for an. stephensi have been defined, based on egg morphology. the aim of the current study is determining the ability of different geographical populations of an. stephensi in the transmission of plasmodium berghei using anka strain of this parasite. four geographical p...

b a ckground: using special lotions and repellent sprays on skin is one of the effective methods to prevent arthropods biting which was verified in this study. m e t hods: essential oils of four plants ( satureja khuzestanica, salvia sclarea , lavendula officinalis and myrtus communis ) were separately extracted by clevenger used hydro distillation method. then separated solutions with 10%, 20%...

PCR based molecular markers are powerful tools for the analysis of genetic diversity for which isolation of good quality genomic DNA is essential. This paper presents a comparison of three DNA extraction methods for 1, 5 and 10 larvae of Aedes aegypti. First method employing DNAzol® involves simple and one step protocol for DNA isolation where maximum purity (A260/A280 1.9) was obtained with si...

www.sciencemag.org SCIENCE VOL 334 9 DECEMBER 2011 1317 COVER Scanning electron micrograph of a female Anopheles stephensi mosquito, a transmitter of malaria (proboscis length: ~0.6 millimeters). To drive malaria eradication, new medicines that target all stages of the malaria life cycle are needed. In their study, Meister et al. used thousands of A. stephensi mosquitos to identify chemical cla...

Plasmodium berghei-infected blood from mice was inoculated into primary cell cultures (PCC) obtained from the mosquito Anopheles stephensi. Immature and mature ookinetes of Plasmodium berghei, which developed in these cultures were studied with the scanning electron microscope. Immature ookinetes had a bulbous-like structure at the posterior end and a slightly wiinkled surface. Mature ookinetes...

b a ckground: the long-lasing insecticide impregnated nets (llins) is considered as an effective tools for malaria vector control. the aim of this study was to evaluate the residual efficacy of alpha-cypermethrin long lasting im- pregnated nets (llin-interceptor®) against anopheles stephensi using tunnel test. m e t hods: the wash-resistance of interceptor® nets were assessed under laboratory c...
