Larvicidal efficacy of some Cucurbitacious plant leaf extracts against Culex quinquefasciatus (Say)

Larvicidal efficacies of extracts of five species of Cucurbitacious plants, Momordica charantia, Trichosanthes anguina, Luffa acutangula, Benincasa cerifera and Citrullus vulgaris were tested against the late third larval age group of Culex quinquefasciatus. The larval mortality was observed after 24 It exposure. The LC50 values of M. charantia, T anguina, L. acutangula, B. cerifera and C vulgaris were 465.85, 567.81, 839.81, 1189.30 and 1636.04 ppm respectively. (C) 2004 Elsevier Ltd. All rights reserved.
