| Abstract | ||
| The extremely hazardous effects of the local insecticidal alternatives namely; mineral oil CAPL-2; organic acid; i.e. citric acid as well as biocides included profect evaluated against the predaceous insect; Scymnus syriacus Mars. Stages (egg, Larvae, pupae and adult) in comparable with the conventional insecticide; Nuvacron. Four Experiments were carried out for determination the hazardous effects of insecticidal alternatives and Navacron by using their recommend rates for controlling either aphid/firstly for determination of their ovicidal effect secondly, determination of their toxic effect on the larval stage, the third one for determination their efficacy against pupae and the fourth experiment was aimed to determine their toxic effect on the adult stage. Two methods were used for the evaluation the type stage of the natural enemy, where in case of non-feeding stages included egg and pupae were exposed directly spraying with recommend rats of the components used for those stages. Concerning feeding stages; i.e. larvae and adult was introduced to the leaves were sprayed with the recommended rates of the tested materials forementioned previously. The obtained results indicated that the conventional insecticide ie. Nuvacron was the most most hazarvdous treatment against all stages of the predaceus insect Scymnus syriacus Mars. While the citric acid was the most safe component followed by the tested biocide; as well as CAPL-2. It could be concluded that the insecticidal alternatives should be used in the IPM programs for controlling the cotton aphids in the objective of keeping the natural enemies to do their effects as control agent. | ||
