Abstract - Issue Nov 2008, 29 (6) BackLarval susceptibility of Aloe
barbadensis and Cannabis sativa against Culex quinquefasciatus,
the filariasis vector Prejwltta Maurya, Lalit Mohan, Preeti Sharma and C.N.Srivastava* Applied Entomology and Vector
Control Laboratory, Department of Zoology, Faculty of Science, Dayalbagh Educational Institute (Deemed
University), Dayalbagh, (Received:
October 22, 2006; Revised received: April 20, 2007; Accepted: May 05, 2007) Abstract: Larvicidal
potential of petroleum ether, carbon tetrachloride and methanol extracts of
Aloe barbadensis and Cannabis sativa has been
investigated against Culex quinquefasciatus.
Among the extracts examined, Carbon tetrachloride extract (Cte) of Aloe barbadensis
was the most effective with LC50?
values of 15.31 and 11.01 ppm after 24 and 48
hr of exposure, respectively, followed by pertoleum
ether extract (Pee) of A. barbadensis, Cte of C. sativa, methanol extract (Mee)
of A. barbadensis, methanol and petroleum ether of C.
sativa, LC50 being 25.97, 88.51, 144.44, 160.78 and 294.42 ppm after 24 hr and 16.60, 68.69, 108.38, 71.71 and 73.32 ppm after 48 hr of post treatment, respectively. Cte of both the plants exhibits potential larvicidal activity and can be used as ecofriendly
alternative in the management of the filariasis
vector, Culex quinquefasciatus.
