| Abstract | ||
| This study includes a comparison among some plant , alcoholic and aquatic extracts with Dichlorovos in mixture level (1-3) insecticide-extract after 24 ,48 hour of treatment on Callosobruchus maculatus (Fab). This study used some seeds and fruits of Peganum harmala ,Citrullus colocynthis and Datura innoxia .Then the treatment of complete insect is treated with mixture of alcoholic and aquatic extracts with disinfectant with the concentration of (1.25,2.50, 5.00,10.00,30.00,60.00)ppm/complete with the whole mixture of (1-3) insecticide-extract with draining method as accurate way on temperature reach (30+1)c and moisture reaches (70+2)% and observing the results after 24 , 48 hours of treatment ,That the whole proportion kills 100% of the same concentration .while the mixture of extracts related to Peganum harmala with disinfectant which was the least influence than other alcoholic extracts that achieves proportion of killing (70.00, 73.33)% of the same concentration after 24,48 hours of the treatment respectively . therefore alcoholic plant extracts have surpassed upon the aquatics extracts in their effect on Callosobruchus maculatus (Fab) in mixture proportion reaches (1-3) insecticide-extract after 24 , 48 hours of treatment. | ||
