The females are brownish-red in colour and oval in shape. Aonidiella aurantti or Red Scale are an insect pest found commonly on Citrus species. Aonidiella citrina or yellow scale is an armored scale insect from the family Diaspididae. The host stage and species utilized by a parasitic mite, Hemisarcoptes cooremani Thomas (Acari: Hemisarcoptidae), was studied to evaluate the mite's potential as an augmentative biological control agent against California red scale, Aonidiella aurantii (Maskell) (Diaspididae: Homoptera). The control of A. aurantii has encountered many difficulties, which has raised interest in alternative control methods (Vacas et al., 2010). The Aonidiella aurantii infests branches, leaves and fruits, especially of the Lemon in which it causes damage similar to that of other Cochineals: leaf yellowing, phylloptosis and general deterioration of the plant; furthermore, the affected fruits drop prematurely and are heavily depreciated. on Aonidiella auranlii on orange from Cuba, on Chrysomnpha!us aonidum on orange from the Bahamas, on lschnaspis longirostris on Ficus nitida from Cuba, on Lepidosaphes beckii on citrus from Costa Rica, Cuba, and Jamaica, and on Pseudaonidia articulatus on … They can walk, be blown by breezes, and there is even evidence of them riding on other insects. Adult females are legless and immobile.

Complex trophic relationships, such as apparent competition between two key citrus pests, were revealed. Aonidiella aurantii (Hemiptera: Diaspididae) is considered a key pest. Journal of the Entomological Society of Southern Africa 34: 159-178.

Aonidiella aurantii or red scale is an armored scale insect and a major pest of citrus.It is thought to be a native of South China but has been widely dispersed by the agency of man through the movement of infected plant material. Amongst the latter, Aphytis melinus has been employed with success as a biological control agent against California red scale in Morocco. The Forest Health Technology Enterprise Team (FHTET) was created in 1995 by the Deputy Chief for State and Private Forestry, USDA Forest Service, to develop and deliver technologies to protect and improve the health of American forests. Entomology Section, Outspan Citrus Centre, S.A. 1996. Aonidiella citrina usually attacks the leaves and fruit but rarely the bark (whereas A. aurantii occurs on all aerial parts of the plant). Releases were made intermittently from 1966 onwards, but while the parasites proved fully effective against Chrysomphalus dictyospermi (Morg.) On greenhouse roses. (2011).
