This leads to the search of insecticides of botanical origin which can serve as a suitable alternative biocontrol technique. Many plants have been reported to have mosqitocidal activity but only few have been used in the field. Since the plants are not clearly characterized and active principles for mosquitocidal activity are not determined properly. There is a need for the development of new botanical insecticids. In our present work Acalypa fruricosa and Andrographis peniculata as thoroughly studied for its mosquitocidal activity.
