Abstract : This research was conducted through two years of estimation (2011 2012) in mango orchards at Kalubyia Governorate, Egypt. The results indicated that this pest had 3 peaks in the year, 2011. The 1st was recorded at the 1st of May, the 2nd was recorded at the 1st of August while the 3rd at the 1st of November. In the year 2012 four peaks of this pest were recorded, the first peak at the 1st of Jan., the second at the 16th of May, the third at the 1st of November and the 4th peak was recorded at the 16th of December. The temperature and relative humidity had highly significant effect on the population of Aulacaspis tubercularis through the two years of estimation. The relationship between different densities of insect population and the associated injury on mango leaves was also estimated. It is concluded that the period from April to August was more suitable period to control this pest to prevent the injuries of leaves, shoots and fruits from reaching its maximum level.
