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...

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 ...

background: recently, essential oils and extracts derived from plants have received much interest as potential bioactive agents against mosquito vectors. methods: the essential oils extract from fresh peel of ripe fruit of citrus aurantium and citrus paradisi were tested against mosquito vector anopheles stephensi (diptera: culicidae) under laboratory condition. then chemical com­position of th...

The utility of using evolutionary and ecological frameworks to understand the dynamics of infectious diseases is gaining increasing recognition. However, integrating evolutionary ecology and infectious disease epidemiology is challenging because within-host dynamics can have counterintuitive consequences for between-host transmission, especially for vector-borne parasites. A major obstacle to l...

BACKGROUND Biting habit of mosquitoes plays an important role in the epidemiology of mosquito-borne diseases. Mosquitoes use a set of elaborate sensory modalities to find their preferred hosts by exploiting cues emanating from a nearby host. It has been suggested that the chemical profile of skin can provide further support for anthropophilic mosquito species to find their suitable hosts. This ...

Anopheline mosquitoes are the primary vectors of parasites in the genus Plasmodium, the causative agents of malaria. Malaria parasites undergo a series of complex transformations upon ingestion by the mosquito host. During this process, the physical barrier of the midgut epithelium, along with innate immune defenses, functionally restrict parasite development. Although these defenses have been ...

When Anopheles mosquitoes probe the skin for blood feeding, they inject saliva in dermal tissue. Mosquito saliva is known to exert various biological activities, but its perception by the immune system and its role in parasite transmission remain poorly understood. In the present study, we report on the cellular changes occurring in the mouse skin and draining lymph nodes after a Anopheles step...

BACKGROUND Although urban malaria transmission is low and seasonal, it remains a major public health problem. This study aimed at demonstrating the presence of Anopheles mosquitoes and their potential to transmit malaria in urban settings. METHODS Two cross-sectional surveys were carried out in Blantyre District, Malawi, during the dry and wet seasons of 2008 and 2010, respectively. A map of ...
