Abstract Content

Mosquitoes are small, devasting organism but creates life-threatening diseases like Chikungunya, dengue, zika, yellow fever, malaria and so on. Chikungunya is an arboviral disease carried by Aedes aegypti and Aedes albopictus. However, the lack of effective therapies and vaccines for these diseases highlights the need for alternative strategies to control the spread of vectors and virus. Plant extracts of medicinal plants are considered eco-friendly, are used for the treatment of numerous ailments and vector control worldwide. This has resulted in approximately 25 per cent of currently used drugs being derived from herbal sources. The aqueous and methanolic extracts of two plant species, Psidium guajava and Salvadora persica were tested for larvicidal activity against the Aedes aegypti. The extracts of methanolic and aqueous of both species exerted a pronounced inhibitory effect on larvicides in case P. guajava showed 80-100% while other species S. persica has moderate activity against tested vector. Both species are potential sources of cost effective mosquito larvicides, Being larvicidal, further investigations would be needed to isolate and identify the primary component responsible for the larvicidal efficiency of the effective plants.
