Abstract

The study aimed to investigate the effects of extracts isolated from vitex-sp [white and violet flower] and Anethum graveolens [Dill] on biological performance for eggs and pupal stages of life cycle of the mosquito culex pipiens. The observed mortality was recorded at 24hrs for exposure to test solution.
The present study was performed to determine the ovicidal effect of two species of vitex (violet and white flower) and Anethum graveolens (Dill) showed that highly active against hatchability stem extracts of vitex (white flower) [Lc₅₀=150ppm]. While, the present study was performed the determine the pupicidal activity of two species of vitex and Dill showed that the highly active against emergence of adult stem extracts of vitex (white flower) [Lc₅₀=140ppm].
Conclusively, from these results, it could be concluded that the effects of extracts isolated from vitex-sp [white and violet flower] and Anethum graveolens [Dill] on biological performance for eggs and pupal stages of life cycle of the mosquito culex pipiens. significantly effective in all difference concentrations used with all tested extracts. and safe to environment.
