Ad. Loch, NATURAL ENEMIES OF PINK WAX SCALE, CEROPLASTES RUBENS MASKELL (HEMIPTERA, COCCIDAE), ON UMBRELLA TREES IN SOUTHEASTERN QUEENSLAND, Australian journal of entomology, 36, 1997, pp. 303-306
The natural enemy complex of pink wax scale, Ceroplastes rubens, on um
brella trees, Schefflera actinophylla, in southeastern Queensland was
investigated. An introduced encyrtid, Anicetus beneficus, was the majo
r primary parasitoid, although high rates of hyperparasitisation by th
e native encyrtid Coccidoctonus dubius were recorded. Predators and ot
her parasitoids were minor components of the natural enemy complex of
C. rubens. Implications of this study's findings on the biological con
trol of C, rubens in citrus by A. beneficus are discussed.
