Larvicidal studies of Avicennia marina extracts against the dengue fever mosquito Aedes aegypti (Culicidae: Diptera)

摘要

Aedes aegypti is one of the most important medical insect pest found in tropical and non-tropical areas ofthe world, and its relevance as a model system. This study was undertaken to evaluate the impact ofdifferent doses of extracted Avicennia marina and its silver nanoparticles against 4th instar of Ae. Aegyptias a source of green nano insecticides. A. marina were extracted and Ag nanoparticles (AgNPs) wereprepared fabricated with A. marina. Our results showed that A. marina synthesized AgNPs showed highlarvicidal toxicity against 4th instar larvae of mosquitoes than the extracts alone at 17.53 times. Theseresults suggest that the synthesized AgNPs of A. marina have the potential to be used as a perfect nonharmfulsynthesis compound for the control of the Ae. aegypti larvae.
