Summary
Dawa-e-Hilteet shows potent larvicidal activity against Anopheles stephensi mosquitoes. This herbal extract offers a promising alternative to synthetic insecticides for effective mosquito control.
Area of Science:
- Medical Entomology
- Natural Product Chemistry
- Public Health
Background:
- Mosquitoes transmit diseases, making vector control crucial.
- Insecticide resistance threatens current mosquito control methods.
- Herbal alternatives are needed for sustainable mosquito management.
Purpose of the Study:
- To evaluate the larvicidal efficacy of Dawa-e-Hilteet against Anopheles stephensi.
- To determine the potential of Dawa-e-Hilteet as a herbal mosquito control agent.
Main Methods:
- Bioassays were conducted using five concentrations (25-125 ppm) of Dawa-e-Hilteet.
- Larval mortality was assessed after 24 hours against Anopheles stephensi.
- Log probit regression analysis determined LC50 and LC90 values.
Main Results:
- Dawa-e-Hilteet achieved 91% larval mortality at 125 ppm.
- Mortality increased with higher concentrations of the extract.
- LC50 was 66.799 ppm and LC90 was 119.709 ppm.
Conclusions:
- Dawa-e-Hilteet extract demonstrates significant larvicidal activity.
- The herbal extract is more potent than Neem extract for mosquito control.
- Dawa-e-Hilteet presents a viable herbal alternative for Anopheles stephensi control.
