| The results of this study showed ofaqueousextracts from plant leaves varieties such as (Meliaazedarach , Ricinuscommunis, Xanthium strumarium ) in Aphis neriiboyer. The results showed a variation in mortality percentage according to plant variety , time stageandconcentrations on Aphis neriiboyer. showed a significant mortality percentage during a period of 24 and 48 hr, Meliaazedarachleavesaqueous extractsuperior at 10% concentration , which reached to 66.66 , 100 % for nymphrespectively. Comparison with Ricinuscommunisleaves aqueous extract and Xanthium strumariumleaves aqueous extractswhich reached to 60 , 83.33 and 53.33 ,76.66 % for nymph during a period of 24 and 48 hr. at 10% concentration respectively. Toxicity values have alsoreachedduring a period of 24 and 48 hr,100 , 100 % and 85.29 ,76.92% and 82.85 ,66.66 % for all the Meliaazedarachand Ricinuscommunis and Xanthium strumariumrespectively. Whilerelativity Efficiency values it reached to 120.68 , 150 , 102.94 , 115.38 , 100 , 100 %. at the Meliaazedarach , Ricinuscommunis , Xanthium strumariumduring a period of 24 and 48 hr.respectively.Meliaazedarachleaves extract showed a significant in Comparisonwith theotherplant extracts. | ||
