| Abstract | ||||
| The present work was conducted in the Experimental Farm of the Faculty of Agriculture in Shebin El-Kom to study seasonal population dynamics of Parlatoria ziziphus (Lucas). During the present investigation it was observed that it is often difficult to remove the scales of this insect especially as alive adult females from the citrus infested leaves. It was observed also, that the average numbers on upper surface of leaf were more abundant than that on lower surface. Three annual peaks of abundance were encountered and recorded through both years of study (2008/2009 and 2009/2010) during April (in spring season), October (in autumn season) and December (in winter season). The highest one occurred in October in both years. Thus, the present results may help in planning a successful control program to check the ravages of P. ziziphus below economic injury level. | ||||
