abstract = "The present study was carried out throughout two successive years (2017/2018 and 2018/2019) at Esna district, Luxor Governorate, to estimate the effect of climatic weather factors, physical and chemical characteristics of mango leaves on population abundance and percentages of infestation by Aulacaspis tubercularis (Newstead) on mango trees. Results indicated that this scale insect species occurred on mango trees all the year round. It had four peaks of population abundance per year. Those were recorded on mid-April, mid-June, beginning of October and mid-November during the first year (2017/2018) and at the beginning of April, beginning of June, mid-September and beginning of November during the second year (2018/2019). Furthermore, percentages of infestation incidence by pest showed, also, four peaks per year. Those recorded in mid-April, beginning of July, beginning of October and mid of November, 2017 and during beginning of April, June, September and beginning of November, 2018. The obtained results cleared that the total population density and percentages of infestation by A. tubercularis were higher compared to the subsequent of study. Also, it was generally found that autumn season was more favorable for A. tubercularis activity and infestation incidence than the remaining three seasons. Obtained data confirmed that the population abundance and percentages of infestation by A. tubercularis were, significantly, affected by the recorded weather factors viz. (daily mean air temperature, mean of relative humidity and mean of dew point), in addition to the morphological and chemical characteristics of mango leaves during the two years of study. Also, the leaf area for mango leaves was the most effective variable for the changes in the insect population and the percentage of moisture in mango leaves was the most affecting factors on the incidence of infestation by the scale insect under the two cumulative years.",
