Evaluation of mosquito larvicidal activity of Jasminum species (Oleaceae) crude extracts against the filarial vector Culex quinquefasciatus Say (Diptera: Culicidae)

AUTHOR(S): Raveen R, Samuel T, Arivoli S, Madhanagopal R
ABSTRACT:India is endemic to mosquito-borne diseases which are major health problems in tropical regions. Chemical pesticides have been used for several decades in controlling pests and vectors of various human diseases but resulted in several problems such as resistance and resurgence of pests, affecting human health and ecosystem being disrupted leading to the threat that their continued use may further harm the environment. This necessitated the need for environmentally safe and biodegradable indigenous method of vector control. Plant products are considered to be a potential alternative approach as they are environmentally safe, target specific and biodegradable. In the present study, the crude hexane and chloroform flower extracts of Jasminum auriculatum, Jasminum grandiflorum and Jasminum officinale were tested for the larvicidal efficacy against the third instar larvae of Culex quinquefasciatus at concentrations of 62.5, 125, 250, 500, 1000, 2000, 4000 and 8000 mg/L. Mortality was recorded after 24 and 48 h. Amongst the crude flower extracts of Jasminum species tested, the crude chloroform extract of Jasminum grandiflorum was found to be effective showing 100% mortality at 500 mg/L and LC50 value of 212.10 mg/L after 48 h. Further investigations are needed to elucidate the larvicidal activity of Jasminum grandiflorum crude chloroform flower extract against a wide range of all stages of mosquito species and also the active ingredient(s) of the extract responsible for larvicidal activity should be identified.
