Abstract

Objective: To evaluate the larvicidal activity of the tuber extracts isolated front two species of Cyclamen (Cyclamen mirabile Hildebr. and Cyclamen alpinum Dammam ex. Sprenger) against Culex pipiens L. (Diptera: Culicidae). Methods: Twenty young (first second) or older (third- fourth) instars of the Culex pipiens were exposed to various concentrations (100 to 1 000 ppm) of the extracts. Mortality was recorded after 12-, 24-, 48-, 72- and 96-h of exposure. Results: We determined that the young larval stages were more susceptible to the extracts in comparison with the older larval stages. A comparison of LC50 and LC90 values has shown that Cyclamen mirabile was more active than Cyclamen alpinum. Conclusions: This study is the first to report on the larvicidal activity of the extracts of Cyclamen species against Culex pipiens. More studies are needed to isolate and identify the active components involved, their mode of action, and effects on other mosquito and pest species.
