| Abstract | ||
| Studies on the effect of alkaloid crude compounds of Nicotiana tabacum and Peganum harmala on the mortality rate of egg & larval stages of Chrysomya albiceps was conducted Result showed that there is a higher difference between the two plants ,the alkaloid compounds of N.tabacum had a successful effect on mortality percentage which reached 96.6% at a higher conc.for the egg stage ,while the lower mortality percentage reached 17.7% at 10% conc. by the influence of alkaloid compounds of Peganum harmala for the same stage after 24 hour of treatment ,So did that with larval stage in which the alkaloid compounds of N.tabacum caused ahigher mortality percentage of 100% at the conc. 50% for the 1st and 2nd larval stage , In addition to that the lower mortality percentage reached 6.6% at 10% conc. for the 3rd instar by the influence of alkaloid compounds of Peganum harmala ,as well as immature stages mortalities were found to be directly correlated with the time of treatment . | ||
