Abstract
There has been an incomplete understanding of the role that habitat, alternate hosts, and adult
movement plays in NY fruit infestations by obliquebanded leafroller (OBLR). Our intention was
to get a temporal and spatial picture of summer larval re-infestation patterns. The study was set
up on 3 commercial farms (18-33 A, total size) with a history of OBLR injury. To eradicate the
overwintered larvae, an unrealistically aggressive early season spray program was used. Summer
generation adults were monitored using a network of pheromone traps located at different
orchard strata: edge, mid-interior and center on all 4 ordinal sides (N,S,E,W). Weekly terminal-
and fruit-infestation samples were taken at each station. Although large numbers of adults were
caught in all the orchards, subsequent larval terminal infestations and fruit damage remained low
during the season in all blocks. There were no substantial differences in adult catches, larval
infestations or fruit damage in the different orchard strata. Results suggest that large-scale or
whole-farm OBLR management might reduce damage from summer generation OBLR more
effectively than treating individual blocks or small plots; sampling of fruit might better
determine initial timing and treatment need than the traditional practice of timing preventive
