Use of Clove extract against the larvae of Aedes (Culicidae: Diptera) mosquitoes

Abstract

Insecticides have been commonly used to vector control. The current study has been made to evaluate the effect of Syngium aromaticum (clove oil) against the larvae of Aedes for their biocidal activity. The oil can be used in domestic container due to its biodegradable and unharmful nature. The toxicity of insecticides affects the environment. Antilarval activities were studied using clove oil with methanol and ether separately in different concentrations. The bioassay has been made against the third / early fourth stage larvae of Aedes mosquito. These were exposed with control and clove oil concentrations of 20ppm, 30ppm and 50ppm. The bioassay test has been made or the first time to know the efficacy of clove oil against mosquito larvae and check the mortality within 24 hrs.
