Abstract
 Four releases of egg-parasitoid Trichogrammaevanesces West (Hymenoptera: Trichogrammatidae) to control Spodoptera exigua Hb.were applied. Releases were carried out during March throughout the two seasons (2005/2006 and 2006/2007) in sugar beet fields at El-Aiat, Giza Governorate. The four releases of the parasitoid successfully suppressed the infestation with S. exigua on sugar beet plants. The percentage of reduction in larvae population of this insect were 83.8% in the first season and 80.0% in the second season
