Abstract
This study was conducted for the period from April to June 2013 in the village of Mouradia - Diyala Province / Iraq, to study the effect of isolation fungus Beauveria bassiana (BSA3) Carried on the Millet seeds in concentration 1 × 10⸠and the commercial product Mycotal’s fungus Licanecillium muscarium concentration of 1 × 10â· And bio-pesticide Spinosad utilization rate 0.25 ml / l and the pesticide chemical Hatchi hatchi in reducing the population density of nymphs and adults whitefly Bemisia tabaci, the commercial product Mycotal Excelled significant differences on treatments in other biological treatments reduce the population density of whitefly nymphs with 63%, followed by treatment Spinosad and pathogenic fungus B. bassiana 52% and 44.67%, respectively. And the results show the effect of the treatments in the number of whitefly adults of B. tabaci, where all treatments excelled significantly on the comparison treatment. Also the treatment of the commercial product Mycotal affected in reducing the density of whitefly adults 53%, which significantly excelled on the Spinosad treatment 48.73%, followed by fungus B. bassiana (BSA3) treatment 32.1%. The study proved that the spraying of these pesticides to once may be enough in reducing the community to the extent of pest ambition
