Relative larvicidal potential of Pseudocalymma alliaceum and Allium sativum against malaria vector, Anopheles stephensi (Liston).

摘要

Petroleum ether, hexane and methanol extracts of Pseudocalymma alliaceum and Allium sativum wereevaluated against larvae of Anopheles stephensi. The hexane extract of Pseudocalymma alliaceum wasfound to be the most effective of the extracts tested followed by the hexane extract of Allium sativum. TheLC50 values for hexane extract of P. alliaceum and A. sativum were 8.7 and 7.5 ppm after 24 h, and 10.8and 7.6 ppm after 48 h of exposure. Additionally the LC90 values were 31.0 and 22.1 ppm after 24 h, and25.0 and 15.4 ppm after 48 h of exposure.
