| Abstract | ||||
| This work was conducted in the farm of Delta Sugar Company Research, Kafr El-Sheikh during the two seasons (2005/2006-2006/2007) in order to study the effect of different infestation levels of Lixus junci Boh.larvae to sugar beet leaf petioles on foliage consumption, root, losses and sugar components of sugar beet plants. The results indicated that the fresh leaf and fresh root weight in the three infestation levels (5, 10 and 15 larvae/2 plants) not affected by the infestation with L. junci, but, the root sugar content% affected by the insects in the three infestation levels. Thus, it could be recommended the application of the Integrated Pest Management (IPM) to reduce the damage of this insect before the females laying their eggs. | ||||
