This study investigated the effects of four compounds included Sea- water (compound-1), Sea – water +magnetic + traces of (mixture ) pure ferrous sulphate (FeSo4. 7 H2O) and ferric chloride (Fe cl3. 6H2O) 1:1 (compound-2), Sea – water +magnetic+ full saturation with mixture 1:1(compound-3), and match ( IGR(compound-4), on survival, and reproductive parameters of Pectinophora gossypiella, The results showd that the mortality percentages and fecundity of P. gossypiella were signifcantly afected by all treatments. In females or male , the longevity was decreased when females were exposed to (compound-2 and 3) , while, this period prolongated when treated with Match. The treatments declined significantly the times of adults longevity to 13.3, 10.0, 8.0 and 18.9 days/ female and 9.6, 7.3, 4.3 and 13.0 days / male, respectively, when the adults of P. gossypiella treated with the different compounds of Sea- water, Sea – water +magnetic + traces of mixture 1:1, Sea – water +magnetic+ full saturation with mixture 1:1and match (IGR), respectively, compared to 14.5days/ untreated female and 11.3 days/ untreated males.
At the same times, the total eggs laid /female and hatchability percentages in adults fed on all treatments were highly significantly affected compared with the untreated adults. These data indicated that the high reduction in eggs laid by females was estimated by 68.57 and 60.73 % with Sea – water + magnetic+ full saturation with mixture 1:1 and Sea – water + magnetic+ traces of mixture 1:1, against, followed by 46.3% with IGR compared with control.At the same trend, was noticed in hatchability percentages.
