Defoliation by P. charybdis is a key limiting factor on the performance of Eucalyptus nitens in New Zealand and considerable emphasis has been placed on improving resistance to P. charybdis in this species (Wilcox, 1980; Johnson and Wilcox, 1989).Biological ControlBain and Kay (1989) describe the history of biological control efforts against P. charybdis in New Zealand. As a result, susceptibility to attack by this pest is one of the selection criteria considered by Eucalyptus breeding programmes in New Zealand (Wilcox, 1980; Hathaway and King, 1986; Johnson and Wilcox, 1989; Bulloch, 1991).
