Laboratory assessment of medicinal plant extracts shows significant larvicidal activity in Anopheles and Aedes species, suggesting a potential alternative to synthetic insecticides.
Key Points
The n-hexane extracts exhibited 100% larvicidal activity against An. arabiensis, An. stephensi, and Ae. aegypti larvae at 2000 ppm.
Probit analysis provided LC50 values ranging from about 412 to 2139.91 ppm across various plant extracts, demonstrating their efficacy.
The study utilized 80% methanol and n-hexane extracts to assess the larvicidal effects under controlled laboratory conditions.
Findings indicate a need for future research focused on isolation and characterization of active compounds from effective n-hexane extracts.
