Abstract

The present work was carried out at Diarb- Nigm district, Sharkia Governorate, during the two sugar beet seasons 2015/2016 and  2016/2017, to study the seasonal fluctuation and number of  generations of  Pegomyia mixta (Vill) and seasonal fluctuation of the predators Coccinella undecimpunctata (L.), Paederus alfierii (Koch.), Chrysoperla Carnea(Stephens),  Scymnus sp.andtrue spiders. The seasonal fluctuation of  P. mixta (eggs and larvae) on sugar beet plants recorded two peaks during each season. Peaks of eggs were recorded in 22nd of February and 11th of April, in the first season, while the second season, these peaks were recorded in 27th of February and 17th of April. Peaks of larvae were recorded in 7th of March and 18th of April in the first season while the second season, it recorded in 13th of  March and 24th of April. P. mixta eggs and larval were recorded were recorded three generations during each season. The peak of C. undecimpunctata  and P. alfierii has occurred in 21th of March and 20th of March for the first and second  seasons. The peak of C. Carneawas recorded in 14th of March and 13th of March for the two seasons. The peak of true spiders was recorded in 11th of  April  and 17th of  April  for the two seasons.
