OBJECTIVE To investigate the larvicidal efficacy of different extracts of Ficus benghalensis L. against Culex quinquefasciatus Say, Aedes aegypti L. and Anopheles stephensi L. (Diptera: Culicidae). MATERIALS AND METHODS Larvicidal efficacy of the crude leaf extracts of Ficus benghalensis with three different solvents like methanol, benzene and acetone was tested against the early second, thir...

Mosquito larvicidal properties of Mirabilis jalapa (Nyctaginaceae) against Anopheles stephensi, Aedes aegypti & Culex quinquefasciatus (Diptera: Culicidae)

Larvicidal activity of some plant extracts to larvae of the mosquito Culex quinquefasciatus (Say 1823).

OBJECTIVES AND METHODS Searching for potent plant larvicides, crude aqueous extract of the latex of Uschar (Calotropis procera) and Labakh (Ficus benghalensis) were tested against the fourth instar larvae of the lymphatic filariasis vector Culex quinquefasciatus (Diptera: Culicidae) using the conventional methods recommended by the WHO. Likewise, the toxicity level of Malathion was tested. The ...

Mosquito repellent action of Blumea lacera (Asteraceae) against Anopheles stephensi and Culex quinquefasciatus

Petroleum ether extract of Blumea lacera was screened under laboratory conditions for repellent activity against mosquito vector Anopheles stephensi Liston and Culex quinquefasciatus Say (Diptera: Culicidae). The repellent activity of Blumea lacera extract was tested against mosquitoes in comparison with the DEET, which was used as a positive control. Results obtained from the laboratory experi...
