Abstract
Mosquito-borne diseases are a significant public health concern in
India, where 404 species and subspecies of mosquitoes belonging to 50 genera
and 2 subfamilies have been identified to spread various diseases. Malaria was
previously a major concern, however, recently, malaria cases have been
decreasing, while Japanese encephalitis (JE) and dengue cases have been rapidly
increasing, with a high case-fatality rate. Aedes aegypti mosquitoes
spread Dengue viruses. This study aimed to evaluate the efficacy of the aqueous
extracts of Argemone mexicana leaves, flowers, and roots against the
fourth instar larvae of Ae. aegypti. The results showed that A.
mexicana leaf extracts performed better than flower and root extracts.
Concentration-dependent efficacy was observed, with leaf extracts exhibiting
69.57 ± 2.83% mortality at 10% concentration, while flower and root extracts
showed 60.87 ± 1.76% and 56.52 ± 3.46% mortality, respectively. At 1.25%
concentration, all the extracts were not effective, with leaf, flower, and root
extracts showing 21.74 ± 2.67%, 17.39 ± 2.83%, and 13.04 ± 2.11% mortality,
respectively. At 5% concentration, flower and root extracts delivered less than
50% mortality, while leaf extracts showed 60.87 ± 2.67% mortality. The study
clearly showed that the aqueous extracts of A. mexicana are effective
against the fourth instar larvae of Ae. aegypti.
