| Abstract | ||||
| Three materials namely; the insect growth regulator (Admiral) 0.5%, the organophosphoate pesticide (Malathion 57% Ec.) at 0.15% and the mineral oil (Supermox) at 1.5%, were tested for against the mealy bug, Icerya scychellarum (w) infesting mulberry trees in Giza. A total of 30 branches, per treatment, were examined per and post–treatment. The after one, two, three, four, six and eight weeks of Summer application. Reduction % in different stage of the insect, proportional to per- treatment counts, were estimated according to Henderson and Tilton (1955). Data subject to Duncan’s multiple range test (Duncan 1951) 0.05, 0.01 between treatments and their efficacy on the different insect stages . | ||||
