REFINEMENT OF BIO-BASED APPROACHES TO REDUCING INSECTICIDE USE AGAINST PLUM CURCULIO AND APPLE MAGGOT -2004
 

Summary: REFINEMENT OF BIO-BASED APPROACHES TO REDUCING INSECTICIDE USE
AGAINST PLUM CURCULIO AND APPLE MAGGOT - 2004

This trial was conducted in mixed plantings of fresh and processing apples on two
commercial farms in Wayne County, NY, in cooperation with researchers overseeing and
additional 22 similar plots in the six New England states as part of a Univ. of Massachusetts
USDA NE Regional IPM project initiated by Ron Prokopy in 2003. The field trials conducted in
2004 constituted the first year of a 2-year validation and demonstration of the effectiveness of
the following advanced-level IPM tactics in commercial orchards:
1 - For plum curculio (PC), an optimal trap tree approach to determine need and timing of
insecticide use against PC in comparison with existing approaches based on calendar-driven
sprays or heat-unit accumulation models.
2 - For apple maggot (AM), an orchard-architecture-based ranking system for deploying
odor-baited pesticide-treated spheres for direct control of AM in comparison with existing
approaches to AM control based on calendar-driven sprays or monitoring-trap-capture-driven
sprays.
Materials & Methods
Three non-replicated treatments were set up in plots 1.31.9 A in size at each of two
