| Abstract | ||
| Nine chemicals [four IGR insecticides [Lufenuron (match@), Chromafenozide (Acro@), Pyriproxyfen (Admiral@) and RH- 2485 (Runner@)], Kz mineral oil and four binary combinations] were evaluated on Guava trees against the soft scale insect Iceria aegyptiaca (Douglas) (Homoptera: Margarodidae) at El-Sabahia Research Station, Alexandria Governorate during September, 2004. Mortalities were recorded at zero, one, two, three, four and eight weeks. Also, mealybug from freated Guava trees had been collected to investigate the effect of the tested chemicals on alkaline phosphatase (AIKP), Alanine transferase (ALT) and Aspartate transferase (AST) enzymes activity, There were no significant differences among the chemical combinations, which caused more reduction effect than single treatments, and so they affected enzyme activity by the same trend. It could be concluded that Kz oil enhanced the toxicity effect of IGRs. | ||
