 Signs & symptoms  Robert Macfarlane 1999-10-29 
Causes yellow chlorotic spots when feeding on leaves. When citrus fruits are attacked, yellow spots appear at the feeding sites. Scales on citrus fruit render the fruit unattractive.
 Morphology  Robert Macfarlane 1999-10-29 
The female scale is round and usually dark purple; the exuviae paler and subcentral. The male scale is similar to that of the female, but smaller and oval.

The adult female is recognisable from other species by the rather wide pygidium with the posterior end gently rounded, not pointed; by the fairly numerous ducts in the second and third furrows; and by the cluster of small submarginal ducts on segment 2 of the abdomen.

 Ecology  Robert Macfarlane 1999-10-29 
Eggs are laid under the scale of the female insect. the crawlers emerge within a few hours; they are easily dispersed by wind, insects, and cultivation practices. the young scales are found mainly along the midribs and veins of leaves, or in depressions in the fruit. After settling the nymphs start secreting the characteristic waxy scale.

Parthenogenesis does not appear to be of significance in this species. The winged adult males are very short-lived and do not feed.

Polyphagus on both dicotyledons and monocotyledons.
 Dispersal/vectors  Robert Macfarlane  
 Management  Robert Macfarlane 1999-10-29 
Commonly chemical controls are not required in Pacific Island situations. Careful use of cultural and biological controls and good plant management are all that are required. It is parasitized by a wide range of hymenopterous parasites and several species of Coccinelid beetles have been reported feeding upon it.

Outstanding biological control is achieved by the parasite Aphytis holoxanthus — an achievement that has completely eliminated the need for chemical control of Florida red scale.

 Notes  Robert Macfarlane 1999-10-29 
Pantropical CIE. Map. A.4

Wide host range, but particularly common on Citrus species. Found on coconut, date palm, mango, cinnamon, and a wide range of monocotyledons and dicotyledons .
