Abstract
This research include study the efficiency of different concentrations ( 1, 3 , 5 ) This research include study the efficiency of different concentrations ( 1, 3 , 5 ) % of hot and cold fruits aqueous extracts of Citrullus colocynthis on mortality percentages of three larval instars of house flies Musca domestica after ( 24 , 48 , 72 ) hours from treatment , and then the accumulation mortality percentages in treated larvae was recorded after 72 hours. The results of present study showed that the hot and cold aqueous extracts caused high effects on mortality of all larval instars of house flies . Highest mortality percentages was recorded in first larval instars when treated with both aqueous extracts compared with lower mortality percentage was recorded in other larval instars . In all larval instars the highest mortality percentages was recorded after 24 hours of treatment by both aqueous extracts . The highest accumulation mortality percentage 93.6 % was recorded when first larval instar was treated with 5 % of cold aqueous extract while the accumulation mortality percentage 83.6 % was recorded in first larval instar treated with hot aqueous extract . The accumulation mortality percentages in all larval instars were higher when treated with cold aqueous extract than others when treated with hot aqueous extract in all extracts concentrations which using in present study . % of hot and cold fruits aqueous extracts of Citrullus colocynthis on mortality percentages of three larval instars of house flies Musca domestica after ( 24 , 48 , 72 ) hours from treatment , and then the accumulation mortality percentages in treated larvae was recorded after 72 hours.
