McLaren, G.F., & Fraser, J.A. 1992 Leafroller and codling moth flights in Central Otago.. Orchardist of New Zealand 65(9): 21.

Notes: Abstract: Leafrollers and codling moth are the most important insect pests of export pipfruit; the gap between leafroller generations would be an opportunity for pesticide reductions in late January, however, populations of codling moth and crawlers of oystershell scale (Quadraspidiotus ostreaeformis) might increase infestation.
