| Abstract | ||||
| the present investigation was carried out at the experimental farm of Agricultural Research Centre, Giza Governorate, Egypt throughout two successive seasons (2010 and 2011) on chicory plants. Obtained results clearly indicated the following: 1) Twenty seven species of insects and mites were surveyed on Chicory plants during the two successive growing seasons. 2) Eight insects and mites considered important pests. 3) The spider mite Tetranychus urticae Koch proved to be the most abundant species during the two growing seasons showing the highest population density general mean recording 26. 47, 15.60 movable stages/sample in the two seasons, respectively. The lowest density was obtained with the phytophagous mite Bryobia sp. 4) Six insect pests their population density general means were intermediate, these insects were the aphid Uroleucon ambrosiae (Thomas), the white fly B. tabaci (Genn.), Thrips tabaci Lind., the potato leaf hopper Empoasca decipiens (Paoli), the sugar cane mealy bug Saccharicoccus sacchari (Cockerell) and the sugar beet fly Pegomyia mixta (Will) during two seasons. | ||||
