Larvicidal potential of Cyathea species against Culex quinquefasciatus

Original Research
<p>Resistance to insecticides has persuaded researchers to find new methods to control <em>Culex quinquefasciatus </em>proliferation. Plants may be a source of alternative agents for mosquito control due to ever-growing insecticide resistance in mosquito vectors and environmental imbalance caused by synthetic insecticides. The present study was intended to study the larvicidal activity of selected <em>Cyathea</em> species against the filarial vector <em>Culex quinquefasciatus. </em>Larvicidal potential of different extracts were evaluated and larval mortality were recorded. The larvae were more sensitive to ethanolic extracts of studied three <em>Cyathea </em>species when compared to other extracts. Acetone, chloroform and petroleum ether extracts were considered to be less effective. The LC<sub>50 </sub>values of different extracts ranged from 320.72 to 657.03 µg/ml. The results exhibited that the tested three <em>Cyathea </em>species showed concentration dependent potential larvicidal effects and also provide an indication of possible bioactive properties.</p>
