Adulticidal properties of Cardiospermum halicacabum plant extracts against three important vector mosquitoes
Autor(es): Govindarajan, M.; Sivakumar, R.
Resumo: To determine adulticidal activitiy of hexane, ethyl acetate, benzene, chloroform and methanol leaf extracts of Cardiospermum halicacabum against Culex quinquefasciatus (Cx. quinquefasciatus), Aedes aegypti (Ae. aegypti) and Anopheles stephensi (An. stephensi). The bioassay was conducted in an experimental kit consisting of two cylindrical plastic tubes both measuring 125 x 44 mm following the WHO method; Mortality of the mosquitoes was recorded after 24 h.RESULTS, The adulticidal activity of plant extracts showed moderate toxic effect on the adult mosquitoes after 24 h of exposure period. However, compared to other solvents highest mortality was found in methanol extract of C. halicacabum against all the three mosquitoes. Among them An. stephensi produce the highest LC50 and LC90 (186.00 and 346.06 ppm) values. From the results it can be concluded the crude extract of C. halicacabum was an excellent potential for controlling Cx. quinquefasciatus, Ae. aegypti and An. stephensi mosquitoes.
