الملخص EN

A alcoholic extracts of the plant Juncus rigidus and the stems of Capparis spinosa had been prepared, and the biological activity on the larval stage and pupal instars of Calliphora vicina had been studied .

Results showed that alcoholic extract of J.

rigidus had the more effectiveness than alcoholic extract of C.

spinosa on the mortality rate of the three larval stages, also the first larval stage was the more sensitive to the extracts than the other stages.

The highest mortality rate for the larval stages had been recorded in the concentration 75% was 83.33% , 56.66% and 46.66% for the first larval stage, second and third respectively for the J.

rigidus extracts .The mortality ratio for C.

spinosa was 66.66% , 53.33% and 43.33% for the same stages receptivity and for the same concentrations.

Results also showed the effect of the extracts on the pupal instar by decreasing the weight of the pupae and their mortality excluded to the deforming of the adults coming from it in dwarfing and of the wings and death.

Alcoholic extract of J.

rigidus was the more effective , it recorded less rate of the virgins weight which is 0.085 gm\30 virgin in the concentration 75% compared with control whose their average weight was 0.65 gm , the highest mortality ratio for virgin was 66.66% and the highest deforming ratio for adults 60% and the highest mortality ration for the excluded adults 66.66% in the same concentration , while the C.

spinosa extract recorded less rate for the virgin weight 0.226 gm\30 virgin in the concentration 75% , the highest ration for the mortality of virgins and adults and the deforming ratio were 56.66% ,43.3% and 33.33% respectively of the same concentration .
