The tomato-potato psyllid (TPP), Bactericera cockerelli (Sulc) (Hemiptera: Triozidae ) is an economically important crop pest that not only causes damage through its feeding but also transmits the bacterium, “Candidatus Liberibacter solanacearum”, which causes zebra chip disease in potato. TPP is also associated with psyllid yellows disease of potato, tomato and capsicum. Both zebra chip and psyllid yellows cause signific a nt yield losses, plant mortality, decreased quality, and increased control-related costs. This invaded New Zealand in early 2006 and has now spread through most of the country. Laboratory and field experiments were conducted to determine the population development, phenology and life history parameters of the tomato-potato psyllid and to in
