The present study aimed to evaluate the efficacy of the methanolic extract of Enteromorpha compressa against the 3rd larval stages and adults of Musca domestica and Calliphora vicina. Three concentrations of the methanolic extract of E. compressa (5, 10, and 20) g/L are used. The results showed that the mortality of M. domestica larvae varied from 26.6%, 66.6% to 100% at the concentration of 5 g/L, 10 g/L, and 20 g/L respectively after 24 h of treatment, but after 48 h at the same concentration, the mortality were 33.3%, 76.6%, and 100% respectively. The LC50 are 7.179 g/L for 24 h and 6.469 g/L for 48 h of treatment. The mortality of M. domestica adults were 33.3%, 46.6%, and 73.3% at the concentrations of 5 g/L, 10 g/L, and 20 g/L respectively after 24 h, and at the same concentration of extract, there were mortality about 43.3%, 66.6%, and 100% after 48 h respectively. The LC50 were 9.653 g/L for 24 h and 6.230 g/L for 48 h. The mortality of C. vicina larvae were 10%, 46.6%, and 83.3% at 5 g/L, 10 g/L, and 20 g/L concentrations respectively after 24 h and 23.3%, 53.3% and 90% after 48 h. The LC50 for larvae was 10.909 g/L for 24 h and 8.678 g/L for 48 h. The mortality of C. vicina adults were 20%, 33.3%, and 56.6% at concentrations of 5 g/L, 10 g/L, and 20 g/L at 24 h, and 43.3%, 63.3%, and 86.6% at 48 h. The LC50 for adult C. vicina were 16.778 g/L for 24 h and 6.368 g/L for 48 h after treatment.
