Tagetes minuta L. is considered as an annual plant growing in the temperate zones of South America. It has been used as carminative, anti-inflammatory, anti-abortion,vermifuge, bronchodilator and hypotensive. In the current study the locally cultured plant of Tagetes minuta L. was studied for phytochemical and larvicidal properties.The phytochemical analysis of aerial pa...

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%...

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...

background : considering the disadvantages of chemical insecticides, we aimed to evaluate vorticella parasites for control of mosquito larvae of anopheles stephensi and aedes aegypti at different larval stages. methods: vorticella sp infected mosquito larvae were crushed in the 0.85% saline and homogenized well to get vorti­cella in suspension. the effects of vorticella sp infections on larval ...

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...

Glutathione S-transferases (GSTs) are a major family of detoxification enzymes which possess a wide range of substrate specificities. Interest in insect GSTs has primarily focused on their role in insecticide resistance. In this study, following World Health Organization (WHO) routine susceptibility test, DNA was extracted from specimens of Anopheles stephensi collected from the Kazeroon distri...

This study aimed to carry out a malaria situation analysis, species composition and susceptibility levels of the main malaria vector, Anopheles stephensi, to different insecticides in Bashagard. A longitudinal survey was conducted in 2 randomly selected villages in Bashagard. Malaria vectors were sampled by dipping method for the larvae and hand catch, night-biting catch, total catch, and shelt...

After more than 50 years of effective management, resurgent malaria threatens residents in the Menoreh Hills and the foothills of the Dieng Plateau of Central Java, Indonesia. The Dieng Plateau dominates the highland center of Central Java. The steep Menoreh Hills, surrounded by rice paddy habitats, cover approximately 500 km2 with no peaks greater than 1,000 m. We studied epidemic malaria in P...
