Abstract
Mosquitoes are recognized to be carriers of a wide range of illnesses.
Mosquito borne diseases such as dengue, malaria, chikungunya, filariasis,
dengue and, hemorrhagic fever continue to be a major concern to public health
in India and other Asian countries because of the region's tropical or sub-tropical
environment. The present research was conducted against the Mosquito vector, Aedes
aegypti for its larvicidal and ovicidal activities using Datura metel
leaf extracted with acetone, ethanol, and chloroform. After being exposed to
various doses (which ranged from 50 to 250 ppm), 25 Aedes aegypti larvae
in their early third instar underwent analysis. The Datura metel leaf
extracts 24 hours LC50 was calculated using probit analysis. Under
laboratory circumstances, the ovicidal activity against Aedes aegypti was
assessed at different doses ranging from 60 to 300 ppm. After 48 hours
treatment, the rates of egg hatching were evaluated. The LC50 values
of Datura metel extracts against Aedes aegypti larvae in their
early third instar were 189.70, 139.70, and 145.29 ppm, respectively. The Datura
metel ethanol extract had the highest larvicidal efficacy, followed by
those containing chloroform and acetone. In the control group, there was no
mortality. The ethanol extracts of Datura metel exhibited 100 %
mortality at 240 and 300 ppm among the three solvents studied. The findings
suggest that Datura metel crude extracts have the ability to suppress
the Aedes aegypti mosquito.
