FLORIDA RED SCALE Chrysomphalus aonidum (L.) [= ficus Ashmead]--Diaspididae (Contacts) ---- CLICK on Photo to enlarge & search for Subject Matter with Ctrl/F. GO TO ALL: Bio-Control Cases This polyphagous
scale from the Orient, invaded tropical and subtropical areas of North,
Central and South America, the Mediterranean, North and South Africa,
Australia, Asia and the Pacific Islands.
It has been reported particularly damaging to citrus in Israel, Egypt,
Lebanon, Brazil, Mexico, Texas and Florida (Quayle 1938, Bodenheimer 1951,
Ebeling 1959, Kennett et al. 1999). The introduction of
natural enemies began in Israel in 1945-1947 with Comperiella bifasciata
from California. Although this
introduction failed, further efforts in 1956-1957 resulted in the
establishment of two parasitoids, Aphytis
holoxanthus (<150
released) and Pteroptrix (= Casca) smithi (Compere) (ca. 120 released) from Hong Kong (Rivnay
1968). Interestingly, P. smithi was not recovered in the field until 1960. Complete biological control resulted
within 2-3 years along coastal Israel, primarily because of the rapid natural
dispersal of A. holoxanthus (Rivnay 1968,
DeBach et al. 1971). Pteroptrix smithi later dispersed along the coastal plain, and
although its activity was thought to be complementary to A. holoxanthus,
later studies by Steinberg et al. (1986) showed it to be a dominant
species. This project was so
successful that it stimulated a sound integrated control program in citrus in
Israel (Harpaz & Rosen 1971). Aphytis holoxanthus was
then established in Mexico, Florida, South Africa, Australia and Texas, where
complete biological control was also achieved (Maltby et al. 1968, Selhime et
al. 1969, Cilliers 1971, Smith 1978b, Annecke & Moran 1982, Dean
1982). Additional information
pertaining to this project and biologies of hosts and natural enemies may be

1962, Clancy et al. 1963, Broodryk 1964, Flanders 1964, 1966; Quednau 1964,
Rosen 1965, 1967; Muma & Selhime 1967, Bedford 1968, Jimenez-Jimenez
