The cocktail ant Crematogaster peringueyi Emery is disruptive to natural enemies of soft brown scale Coccus hesperidum L., and vine mealybugs Planococcus ficus(Signoret). This ant species provides protection to its hemipteran hosts by constructing carton shelters over the mealybugs (Kriegler and Whitehead, 1962). The common pugnacious ant,Anoplolepis custodiens(Smith), incidentally disturbed the parasitoids of California red scale Aonidiella aurantii (Maskell), while tending soft brown scale in citrus orchards in South Africa (Samways and Tate, 1984; Steyn, 1954).
