Abstract
Ten Egyptian cotton varieties were evaluated for their susceptibility to infestation with the whitefly, B. tabaci (Genn.) under field conditions at Sakha Agricultural Research Station during three successive seasons of 1997, 1998 and 1999. It was found that Giza 89 variety had the highest rate of adult infestation (729, 484 and 501.6 adults/9 leaves) as well as the immature stages (110.9, 130.9 and 156.9 individuals/9 in2) during 1997, 1998 and 1999 seasons, respectively. On the other hand, cotton variety Giza 45 was the least infested with means, of 177.0 and 304.2 adults/9 leaves during 1997 and 1999 seasons, respectively, while for season 1998, Giza 88 had the least infestation (157.2 adults/9 leaves). As for the immature stages, the least infestation level was found in case of variety Giza 45 (18.9, individuals/9 in2) for first and second seasons.
