Abstract
Sugar beet, Beta vulgaris L. is one of two principal sugar crops (sugar beet and sugar-cane) in Egypt and the world. This crop is annually planted in Egypt in about 135,623 feddans and about 54.8% of this area (74,384 feddans) is concentrated in Kafr El-Sheikh Governorate (2000/2001, seasons).’
Sugar beet plants attract numerous insect species during the growing season. These insects have various needs of living and some of : can cause economic damage when they feed on the plants throughout their growth stages. Fortunately, these harmful insects have their own enemies which play a principal role in preventing further multiplication of these pests.
Therefore, this work on sugar beet insect pests and their natural enemies must be mainly of value to beet growers. It should assist the beet growers in making practical decisions on treatments on which to a considerable extent, the profitability of the crop depends.
