Twelfth weekly update on psyllid traps for 2011
TPP numbers are continuing to decline in all areas except for Mid Canterbury, which is experiencing a late-season peak at one site. That’s one of the problems with looking at averages across several sites, a high catch at one site can distort the overall situation. Good examples of this are the Pukekohe and Manawatu averages, where numbers have been influenced by high catches at Pukekohe C and Manawatu A. Most of the other trap sites in these regions have had much lower numbers, so it is worth taking a look at the data tables for your region to see the actual numbers per trap (usually 4 traps per site) at each site in the region.
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.
