Abstract
Present Study was conducted to evaluate the probable effect of the aqueous and ethanolic extracts of Nicotiana tabacum L.and Peganum harmala L.on the mortality of the egg stage aswell as the larval one of the chrysomya albiceps the significant successful of the aqueous and ethanolic extracts of N.tabacum comparison by the aqueous and ethanolic extracts of P. harmala and its effect,which caused 100%, at100% conc.for all stages but reached 0% at 5% conc. by the influence of aqeous extract of P . harmala ,at 5% conc. At exposure for 24 hours. The Results of ethanolic extract and their effect on the egg and larval stage for N.tabacum and P. harmala showed that the effect of ethyl alchole extract N.tabacum was the most successful on the mortality of larval stage 5% conc.of N.tabacum caused an average mortality of 100%while it reached 0% at 5% conc. For the ethanolic extract of P. harmala and the average of mortality rate increased by the increased of conc.it reached 100% for the 1st &2nd instar respectively at the conc.100% At exposure for 24 hours.by the influence of ethanolic extract of N.tabacum .As well as immature stages mortalities were found to be directly correlated with the time of treatment to both plants .Statical results showed that the ethanolic extract of N.tabacum had asuccessful effect on mortality percentage which reached 86.61% while the lower mortality percentage reached 21.48% for the aqeous extract of P. harmala .
