Fourth weekly update on psyllid traps for 2011
Status at 28 January 2011: Potato psyllid numbers are continuing to increase in most North Island locations. TPP numbers are quite variable between sites in each district, please refer to the data tables for more information. Pukekohe numbers are highest at site C, but very low at the other trapping sites. The reduction in numbers at Pukekohe may be due to adverse weather. Waikato numbers remain very low. In the South Island, TPP numbers remain very low in South and North Canterbury, but have increased to just under 10 psyllids per trap in Mid-Canterbury.
See most recent data tables and graphs.
Each week Potatoes New Zealand reports on the number of tomato potato psyllids (TPP) and other species of psyllids in the psyllid traps to help growers monitor and control for the potato tomato psyllid. Traps are localed in Pukekohe, Waikato, Hawkes Bay, Manawatu, North Canterbury, Mid Canterbury and South Canterbury. Numbers of tomato potato psyllids (TPP) and other species of psyllids are reported.
