Abstract
Some ecological studies on sugarbeet insect pests , were conducted in Sakha Agric. Res. Station, Kafr El-Sheikh Governorate, during the two growing seasons 2009/10 and 2010/11 to evaluate eleven sugarbeet varieties ; Francesca, Helsinki, Revel, Sibel and Univers (monogerm); Diamond, Farida, Helioses, Hercule, Maghrible and Pleno (polygerm) for resistance to main insects of sugarbeet plants (Pegomya mixta, Cassida vittata and Scrobipalpa ocellatella) and high yielding potential. The results revealed that two varieties ; Hercule and Helsinkihad the least infestation by P. mixta. On the other hand, three varieties ; Helsinki, Francesca and Helioses had the least infestation by C. vittata while each of Helsinki, Sibel and Francesca had the least infestation by S. ocellatella. Finally, two varieties Maghrible and Revel proved moderate insect population and in the same time increased root (24.44 and 23.75 ton/fed., respectively) and sugar (4.46 and 4.39 ton/fed., respectively) yield.
