Abstract

          Copper sulfate and alum were mixed and formulated after carrying out the necessary experiments as 10 % soluble concentrate (SL). The new formula passed all physico-chemical properties defined for soluble concentrates. It was then tested on the adults and nymphs of the armored scale insect Hemiberlesia lataniae (Hemiptera: Diaspididae) under laboratory conditions, it showed low efficacy on the adults while it showed high efficacy on the nymphs, as its EC50 value for the nymphs was 474 ppm after 72 hours from exposure, the results that were confirmed on experimentation under field conditions on both stages under study, fluctuated percentages of inhibition were obtained in case of adults while it showed high percentage of inhibition on the nymphs. The new formula proved good efficacy on the nymphs of H. lataniae and could be used as an insecticide after completing the other specified experiments in the future.
