Abstract
Studies on some ecological aspects of Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae) and its associated parasitoids and predators on mango trees were carried out at Benha district, Qaliobiya Governorate, Egypt, during two successive years (2014- 2015 and 2015- 2016). The obtained results showed that A. tubercularis had four peaks of activity during April, June, September and January and also, had four overlapping generations in the two seasons of study. Three species of predators were Chrysoperlla carnae (Stephens), Hemisarcoptes coccophagus (Meyer) and Chilocorus bipustulatus (Linnaeus) and three parasitoids species were Habrolepissp. Encarsia sp.and Aphytis sp. were found associated with A. tubercularis on mango leaves. The highest population was in autumn and summer and lowest population was in winter. The heaviest infestations of A. tubercularis were recorded in south and east directions and the upper leaf surface was preferable compared with the lower.
