LARVICIDAL ACTIVITY OF LEAF EXTRACT OF GINGER AND TURMERIC ON MOSQUITO LARVAEAbstract
Dengue fever is an important public health problem in tropical and sub-tropical Continent. Recently the number of severe forms of the disease, dengue hemorrhagic fever, and dengue shock syndrome are increased. Dengue virus, a arbo-virus responsible for dengue fever and spread through its vector, Aedes aegypti. Controlling the mosquito is the good strategy to prevent this disease. The traditional chemical pesticides used to control mosquito have many drawbacks, and natural products are more acceptable in this aspect. The bio-efficacy of ginger (Zingiber officinale) and turmeric (Curcuma longa) ethanolic leaf extract was assessed against the fourth instars larvae of Aedes aegypti, under the laboratory conditions. Both shows moderate activity against Aedes aegypti larvae. However, the combined treatment of both leaf extract (1:1) shows highest activity. Combination of 50 µgml-1 turmeric and 50 µgml-1 ginger killed all of the population within 24 h. This is an eco-friendly and low-cost approach, may use to control Aedes aegypti.
