Phoenicococcus marlatti Cockerell
Common name: Red date scale.
Geographical distribution: World-wide, wherever date palms are grown.
Host plants: Members of the genus Phoenix (palms).
Morphology: The body of the female is reddish, rounded, slightly pear-shaped, about 1.3 mm in length. It bears a white marginal fringe. The males lack wings.
Life cycle: The scale apparently raises four annual generations, although its biology has not been studied in the Middle East. It usually infests the bases of the rachis and does not occur on the apices of the pinnae.
Economic importance: The red date scale is usually regarded as a minor pest, but in Egypt it is an economic pest of date palm. When it occurs in large numbers on young trees it can retard their growth, causing stunting and even decline. The pest’s feeding on date pinnae causes their wilting.
Management: Due to hiding deep within palm trees, chemical control (if necessary) is not recommended, but sanitation of seedlings during planting may reduce the pest’s populations.
