Abstract
The experiment was carried out at Etay El-Baroud Research Station, El-Beheira Governorate during 2007 and 2008 growing seasons. The aim of this work was to evaluate the efficacy of imidacloprid insecticide as seed treatment on the early season sap sucking insects; thrips (Thrips tabaci), aphids (Aphis gossypii), jassid (Empoasea lybica) and whitefly (Bemisia tabaci) on cotton plants. Also, the investigation included the determination of imidacloprid residues in cotton plants. Results indicated that the initial efficiency against thrips was 87.16 and 86.91% and was 94.84 and 93.06 % against jassid in the two seasons, respectively. The residual efficacy was found to be 58.81 % and 57.55% as a general average after seven weeks against aphids, whereas it was 60.35 % and 59.36% against whitefly in the two seasons, respectively. Concerning the residues analysis of imidacloprid in cotton plants by HPLC, the data indicated that the residue amount was 0.0923 and 0.0123 µg/g plant after two and seven weeks of treatment, respectively.
                It can be concluded that early season sucking insects can be controlled using imidacloprid as seed treatment. A reasonable efficacy and considerable residue effect (6-7 weeks after cultivation) was obtained. Imidacloprid insecticide can be applied in IPM programmes to minimize the use of insecticides to keep environment and beneficial insects.
