| Abstract | ||||
| Mulberry trees were heavily infested with the scale insect Hemiberlesia lataniae(S) Therefore, Insect growth regulator (Admiral) 0.5%, the organophosphate Pesticide (Malathion 57%Ec.) at 0.15% and the mineral oil (Supermox) at 1.5%., were tested for against the scale insects infesting mulberry trees in Giza. Reduction% in different stage of the insect proportional to per- treatment counts ,were estimated according to Henderson and Tilton (1955). Data were subject to Duncan’s multiple range test (Duncan 1951) 0.05, 0.01 between treatments and their efficacy on the different insect stages. Results indicated that all tested materials were obvious differences between the pre – treatment counts and the post treatment counts and also, differences occurred among treatments. Moreover, the population density of scale insect H. lataniae was reduced according to the potancy of each compound . | ||||
