Abstract
the present studies were carried out at the experimental farm of the Faculty of Agriculture, Kafrelsheikh, University, during two successive seasons; 2011 and 2012 to study the susceptibility of five soybean varieties under three planting dates, 1st May, 15th May and 1st June to the infestation with the whitefly, Bemisia tabaci (Genn.). In respect to relative susceptibility, Giza 21 appeared susceptible to nymphs of B. tabaci during the two successive seasons while, Giza 35 was the least infested one. Statistical analysis revealed significant differences among soybean varieties and the average number of B. tabaci during the two seasons of study. As for planting dates, the varieties sown on the early planting date had higher population of B. tabaci than those sown on the late ones. Statistical analysis show significant differences between the three planting dates. In the recommended planting date, B. tabaci recorded highly significant positive correlation with nitrogen, zinc, manganese, crude protein, total lipids and silica but had negative significant or highly significant correlation with each of phosphorus, potassium, iron, total carbohydrates and total phenols. As a conclusion Giza 35 was the least infested variety by B. tabaci which had the highest value of carbohydrates, phenols, iron, phosphorus and potassium.
