title: Larval susceptibility of Ajuga remota against anopheline and culicine mosquitos.
abstract: The objective of the present study is to determine the bioefficacy of different crude extracts of Ajuga remota against anopheline and culicine larvae. Larval susceptibility of crude carbon-tetrachloride, methanol and petroleum-ether extracts of Ajuga remota leaves was observed against the malaria vector, Anopheles stephensi and the filariasis vector, Culex quinquefasciatus. Among the extracts tested, petroleum-ether extract was the most effective with LC50 values of 0.033% after 24 hours and 0.029% after 48 hours of treatment against the larvae of Anopheles stephensi. In the case of the larvae of Culex quinquefasciatus, the carbon-tetra-chloride extract exhibited maximum efficacy with LC50 values of 0.043% after 24 hours and 0.026% after 48 hours of exposure, respectively. It is, therefore, concluded that Ajuga remota can be applied as an ideal larvicide against An. stephensi and Cx. quinquefasciatus.
