The objective of this research project is to understand the movement behavior of the adult and larval stages of an apple pest, the oblique banded leaf roller, Choristoneura rosaceana.
Information on adult movement will be used to assess the potential for the spread of insecticide resistance between orchards. Larval movement data will be used to improve the ability of current monitoring methods to predict fruit damage and to maximize the effectiveness of current control methods. Field-based studies of the movement of adult leaf rollers in an orchard using mark-recapture methods and behavioral observations were conducted last year and will be repeated this year. These data will be analyzed and compared with predictions generated by an individual-based movement model to determine whether the movement patterns are random or have a directional component. Empirical data from field studies also will be compared with results from a spatial analysis of 6 years of leaf roller damage records for orchards along the southern bank of Lake Ontario, NY. Additional mark-recapture and observational field work will be conducted this season to understand larval movement within a tree. Data will be collected to determine when the larvae are most active, whether their movement is directional, and how far and how often they move.
