Effect of Moringa oleifera lectins on survival and enzyme activities of Aedes aegypti larvae susceptible and resistant to organophosphate

Researchers investigated whether lectins extracted from Moringa oleifera could serve as a natural larvicide against Aedes aegypti mosquitoes, which transmit dengue, Zika, and chikungunya viruses. Lectins are proteins that bind to specific carbohydrates and can be toxic to insects. The study tested these moringa-derived lectins on mosquito larvae that were either susceptible to or resistant to organophosphate insecticides, examining both survival rates and changes in enzyme activity. This research addresses the growing problem of insecticide resistance in disease-carrying mosquitoes and explores whether plant-based compounds like moringa lectins could provide alternative control methods. The findings contribute to understanding how natural compounds might be developed into environmentally-friendly mosquito control agents, particularly important given the widespread resistance to conventional chemical insecticides that has developed in Aedes aegypti populations worldwide. Such botanical insecticides could potentially offer sustainable vector control solutions while reducing reliance on synthetic chemicals that have become less effective due to resistance mechanisms.
