Abstract
The present work was carried out to study the efficiency of seven pesticides namely, Agreenate , Diazinone, Boma, Major, Chlorosan,  Agrezole and Nasractine on the egg hatchability percentage of the cotton whitefly, B. tabaci (Genn.) under laboratory conditions on soybean plants, and evaluate the efficiency of single and double applications of the tested pesticides against the nymphal stage of whitefly, B. tabaci infesting soybean plants under filed conditions.
Data showed that, the tested pesticides caused high reduction of egg hatchability percentages compared with control . The minimum hatchability percentages of egg caused by Major (4.35%), while the maximum egg hatchability percentages caused by Nasractine (54.03%) compared with  control  (95.52%). With respect to the efficiency of the tested pesticides against nymphal stage of B.tabaci, The results revealed that Chlorosan proved to be the highest effective compound in single and double applications, on the other hand, Agrezole was the lowest effective one in both applications. The other tested pesticides occupied in intermediate positions between the highest and the lowest compounds.
In addition, all treatments showed significant increase in the average weight of 100 seeds of the treated plots as compared with control.
Conclusively, it can be concluded that using the tested pesticides especially Chlorosan against whitefly, B. tabaci can reduce the crop losses in soybean plants under the Egyptian field conditions.
