Furness, G.O. 1977 Chemical and integrated control of the long-tailed mealybug, Pseudococcus longispinus (Targioni-Tozzetti) (Hemiptera: Coccidae) in the riverland of South Australia.. Australian Journal of Agricultural Research 28: 319-332.

Notes: Chemical control of the mealybug Pseudococcus longispinus was most effective if sprays were applied when the mealybugs were in the dispersive crawler stage and when the host plant afforded the least shelter. A two-spray program with sprays applied in August and late November effectively controlled a dense infestation of the mealybug on citrus. Red scale (Aonidiella aurantii (Maskell), the major insect pest of citrus, was also effectively controlled. An overall pest management program has been developed for citrus in which all insect pests are controlled by combinations of natural enemies and insecticides as required. Outbreaks of the mealybug, and other secondary pests, are controlled by sprays of aminocarb or methomyl. These two insecticides prevented the population resurgence of mealybugs in the subsequent generation which occurred when maldison was used. The duration of relatively short toxicity period and the effect on secondary is discussed. An insecticide check experiment failed to demonstrate that natural enemies significantly reduce populations of the mealybug. Possible reasons for the failure are discussed.
