background and objectives: malaria is a remarkable cause of death in the world. several ways are used by researchers to control or to decrease the detrimental effects of the disease, in which natural insecticides with less malaria vectors resistance and lower environmental damages are considered in last decades.the objective of this study was to assess the larvicidal activity of the whole flowe...
The effectiveness of conventional malaria vector control is being threatened by the spread of insecticide resistance. One promising alternative to chemicals is the use of naturally-occurring insect-killing fungi. Numerous laboratory studies have shown that isolates of fungal pathogens such as Beauveria bassiana can infect and kill adult mosquitoes, including those resistant to chemical insectic...
Malaria is an important tropical parasitic disease in the world, and still a major health problem. vector control one of efforts to prevent malaria which aims break chain transmission malaria. Vector includes actions directed against vectors, are intended limit their ability transmit by protecting areas that known be receptive transmission. Identify opportunities aspects can utilized state effo...
An investigation was carried out over a year in the village of Chelow, Hormozgan Province, southern Iran, to study the efficacy of CDC light traps for sampling malaria vectors. The CDC light traps were useful in determining the seasonal and habitat distribution of Anopheles stephensi and An. fluviatilis, the primary and secondary vectors of malaria, in Chelow, as well as other mosquitoes in tha...
Strategies to eradicate the vector-borne infectious diseases (e.g. malaria and Japanese encephalitis) are often directed at controlling vectors with insecticides. Spraying insecticide, however, opens the way for the development of insecticide resistance in vectors, which may lead to the failure of disease control. In this paper, we examine whether the combined use of insecticide spray and zoopr...
The magnitude of regional malaria risk is dependent primarily on the dynamics and distribution of the vector species, which are determined mainly by climate conditions. A coupled model with ecophysiological and climatological factors was developed to estimate the spatiotemporal distribution of the five species of dominant malaria vectors in monsoon Asia. Here, we examined how the potential dist...
