Kilifia acuminata (Signoret)
(Formerly known as Lecanium acuminatum Signoret)
Common name Mango shield scale, acuminate scale.
Distribution: In most warm regions of the world.
Morphology: Body broadly oval, pear-like, pale green or yellow green; without an obvious wax covering nor an ovisac, about 2-3 mm in length. Devoid of tubular ducts. The two posterior pairs of legs much larger than the front pair. Marginal setae conspicuously fringed, anal plates longer than wide.
Life history: On mango this parthenogenetic pest raised two annual generations, producing up to 420 eggs/female in autumn, about 370/female in spring. It usually occurs on the lower sides of host leaves.
Economic importance: An important pest of mango in Egypt.
Biological control: The parasitoids Metaphycus , Encyrtidae, Coccophagus (Aphelinidae) and Scutellista caerulea (formerly known as Scutellista cyanea Motschulsky) (Pteromalidae) are major natural enemies of K. acuminata.
