MOSQUITO LARVICIDAL ACTIVITY OF HYPTIS SUAVEOLENS (L) POIT EXTRACTS PURIFIED FRACTION

Bio-pesticides are playing a very important role in controlling mosquitoes and their larvae. In the present scenario, chemical pesticides are causing several side effects on non-target organisms, particularly in men. Moreover, mosquitoes and their larvae become resistant to chemical pesticides; therefore, chemical pesticides are not much more effective. The conventional use of temephos and pyrethrum creates several health hazards in men, especially in upper and lower respiratory disorders, including allergy, asthma, and rhinitis. The plant Hyptis suaveolens is well known for its aromatic properties. Therefore, it was proposed to apply its purified fraction on different strains of mosquitoes for the evaluation of mosquito larvicidal activities. In the present study, identified and authenticated shade-dried whole plant materials were pulverized to get powder, extracted in various solvents through Soxhletion, and percentage yields were noted down. The main phytoconstituents reported in the extract were alkaloids, flavonoids, terpenoids, and tannin in huge amounts. Due to the presence of the pungent smell of flavonoids, terpenoids, alkaloids, and tannin in Hyptis suaveolens, mosquito larvicidal activities were reported in the purified fraction.
