| Abstract | ||||
| The white mango scale insect, Aulacaspis tubercularis (Diaspididae: Homoptera), is one of the most destructive pests affecting mango trees in Egypt. This study investigates the impact of different mango cultivars on the population dynamics of this insect in New Damietta mango orchards during the 2022 and 2023 seasons. The effects of natural enemies and weather factors, including mean temperature (°C), relative humidity (%), tree orientation, and seasonality, were analyzed. The findings revealed three annual population peaks of A. tubercularis, occurring in February, May, and August across different mango cultivars. The highest infestation levels were recorded during summer, with mean densities of 3623.5 ± 564.3 and 2733.3 ± 434.1 individuals per 125 leaves in the first and second study years, respectively, while the lowest populations were observed in winter. Statistical analysis showed that A. tubercularis populations were significantly influenced by natural enemies and daily means temperature, whereas relative humidity had no significant effect. Additionally, the insect exhibited a preference for the southern orientation of mango trees. These findings provide valuable insights into the seasonal trends and ecological interactions of A. tubercularis, contributing to the development of effective integrated pest management strategies for mango orchards in Egypt. | ||||
