Larvicidal effects of selected plant leaves extract against anopheles mosquito

摘要

Emergence of resistance among mosquitoes is a recent problem. Safe and ecofriendly agents from biological origin is need of the hour. An attempt is made in the present study to analyse the larvicidal effects of the plant leaves extract against anopheles mosquito. Among these selected plants, Catharanthus roseus, Phyllanthus amanls, Acalypha indica, zingiber officinale, cynodon dactylon and Aerva lanata showed the highest level of activity against mosquito larvae. In conclusion, the results obtained that .-the leaves extract used had some bioactive constituents which resulted in the larvicidal effects. Such findings are useful in promoting research aimed at the development of new agents for mosquitoe control, based on bioactive natural chemical components from indigenous plant sources. The use of indigenous plant based products by individual and community can provide a prophylactic measure for protecting against various mosquito borne diseases.
