A white hard scale insect Aulacaspis tubercularis Newstead (Diaspididae) and a green soft scale insect Kilifia acuminata Signoret (Coccidae) as well as four saprotrophic fungi belonging to the genera Alternaria Nees: Fr., Cladosporium Link., Helminthosporium Link ex Fr. and Stemphylium Wallr., were detected based on their morphological features in accordance with the identification keys and descriptions of scale insects and fungi. The infestation of mango leaves with the saprotrophic fungi was interpreted as a secondary infection due to the primary infection with the scale insects as honeydew producers on which the fungal spores develop and reproduce. Therefore, it is recommended to control the scale ins...
