Scientific name

Phoenicococcus marlatti Cockerell




Sphaerococcus draperi Newstead, Sphaerococcus marlatti Newstead, Phaenococcus marlatti Wardle, Kermicoides minimus Tang


The females are small, around 1.5 mm long, spherical in shape and red or reddish in color. Rather than forming a scale covering, the insects embed themselves in masses of cottony, waxy secretions. Mature females are wingless and legless; mature males have wings but do not feed and are very short-lived. Eggs, when laid, are smooth, oval, and pinkish with a pearly lustre. The first instar, or crawler, has well-developed legs. Females have 3 instars while males have 5.


Native to North Africa and the Middle East but has been found almost everywhere date palms are grown, including Europe, Asia, the Caribbean, North America, South America, and Central America. Within the US, only established in Florida; was eradicated from the southwestern US.


Palms: primarily restricted to palms of the genus Phoenix, most particularly date palm (Phoenix dactylifera), but has also been found on desert fan palm (Washingtonia filifera)

Other: has also been reported from Pandanus sp. and Eucalyptus sp.

Additional comments
