Ferrari, R. 1978 Prove di lotta contro Saissetia oleae (Oliv.): osservazioni sugli effetti degli insetticidi nei confronti di parassiti e predator. [Chemical control of Saissetia oleae (Oliv.) effects of insecticides on parasites and predators.]. Annali dell'Istituto Sperimentale per la Zoologia Agraria 6: 69-83.

Notes: Eight insecticides have been employed in control trials against Saissetia oleae. The action of the chemicals on the entomophagous insects has been evaluated by collecting them through Steiner funnels. The author proved also that a single scale insect was able to cover with honeydew 32 olive leaves.
