oa Journal of the Entomological Society of Southern Africa - Parasitism of Florida Wax Scale, Ceroplastes floridensis Comstock, on Citrus in Israel



Population censuses of the Florida wax scale, Ceroplastes floridensis Comstock (Homoptera: Coccidae), and parasites attacking it were made over a 4-year period between 1983 and 1987 in 2 citrus groves in Israel. Two annual generations of the scale were produced in both groves. The most abundant parasite was Tetrastichus ceroplastae Girault (Hymenoptera: Eulophidae). Peak numbers of parasites were synchronized with peak numbers of hosts susceptible to parasitism. Parasites had a significant effect on the host population in one grove, as determined by life-table analysis.
