Abstract

The global impact of malaria and challenges encountered during its control have necessitated the application of multifaceted strategies, including the application of plant-derived agents. Amidst these challenges the proliferation of the vector is becoming hyperendemic in tropical region. This research is focused on the biolarvicidal activities of the methanolic leaf-extracts of Cassia alata, Microdesmispuberula¸ and Spilanthesfilicaulis against mosquito larva. The mosquito larva were assayed in a static non-renewal test. Results showed no mortality for the negative control, and total mortality for the positive control (p<0.05). The C. alata bioassay was the most active with LC50 value of 13.73 ppm, followed by; M. puberula(21.24 ppm), and S. filicaulis (28.86 ppm). This study concludes that methanolic-leaf-extracts of C. alata, M. puberula¸ and S. filicaulis can be recommended for the formulation of biolarvicide for the control of malaria.
