The flowers of this orchard tree presents six fleshy petals, fused two by two, and disposed propeller like. In the center is a cavity which harbors the cone shaped reproductive organs. An eriophyid mite, described by H. H. Keifer as Aculops flechtmann Keifer, 1972, causes considerable bronzing to the petals (Fig. 1-A). Large numbers of this mite attacking the basis of the reproductive organs causes them to dry and drop. On the young fruits, which are squamous, this mite causes some rusting and small necrotic areas (Fig. 1-B). As the fruit grows these small areas remain dark and barky. Very often the necrotic areas are invaded by the false spider mite Brevipalpus phoenicis (Geijskes, 1939), which enlarges the damage. The false spider mite also attacks leaves and green stems; the epidermis of the latter then assumes a barky appearance.
