Screening of Plant Extracts Against a Vector of Arboviruses, Aedes aegypti (Linnaeus) (Diptera: Culicidae)

Aedes aegypti is a vector mosquito of dengue haemorrhagic fever, chikungunya, yellow zika, filariasis and other viral infectious disease-causing pathogens. We tested ethanol extracts the six plant species viz., Cassia fistula, Curcuma amada, Manilkara zapota, Momordica charantia, Sansevieria trifasciata Solanum indicum at dosages 25, 50, 75 100% for their larvicidal effect against third instar larva A. aegypti. observed maximum larval mortality minimum LC50, LC90, LC99 in C. amada (LC50 = 0.14, LC90 9.28 277.97) among extracts. All caused moderate to high mortality, hence, these could be substitute source control as they comprise potential bioactive chemicals generally free from toxicants. Applications natural derivatives reduce cost methods environmental contamination.
