الملخص EN

The alcohol extract of Cuscuta campestris was prepared and its biological effect was studied on the larval star and pupal star of Calliphora vicina.

The results showed that the 1st larval instar was the most sensitive, while the 3rd larval instar was the most resistance to the extract, and the highest mortality rates of the larval instars reach to 90% , 60% and 53.33% for the 1st, 2nd and 3rd instar on the concentration 75%.

The results also showed the effect of the pupal stage on alcoholic extract, which caused morality of pupa and reducing weight so gives abnormal and short adults with abnormal wings, while the highest mortality rate of the pupa reached 60 % on the concentration 75% and the lower pupal weight reached 0.116 gm/ 30 pupa on the same concentration compared with the control which them weight reached to 0.65 gm, and highest abnormality rate of adults reached 33.33 % and highest mortality rates of adults reached 40% on the same concentration.
