The present work is related to the utilization of castor (Ricinus communis) seed cake, biowaste produced during the oil extraction of castor seeds, as efficient mosquitocidal composition against Aedes aegypti and Anopheles culicifacies. The efficacy of coil formulations was evaluated in the Peet Grady chamber and resulted in 90% and 100% knocked down and mortality against A. aegypti and A. Culicifacies, respectively. Further heavy metals' (Cr, Pb, Co, As, Cd, Cu, Mn, and Zn) analysis of the coil was performed using Inductively Coupled Plasma mass spectrometry and was compared with commercially available mosquito repellent coil. Heavy metal analysis revealed that commercial repellent coil had a higher content of heavy metals than the castor seed cake coil. Finding of the present research study indicates that castor seed cake coil has the potential to be used in mosquito vector control. Castor seed cake coil formulation will also open up avenues in future for sustainable utilization of the biowaste.
