Comparison of Soybean Aphid Abundance and Yield Impact on NY Soybean Varieties and Survey of Soybean Aphid Natural Enemies, 2002

Abstract

Weekly surveys for soybean aphid were conducted in five locations from July 7th through September 10, 2002 by summer assistants Lee Macomber and Megan Edlund in soybean variety trials that included 50 varieties. Several cooperative extension educators (Dr. Michael Stanyard and Mr. Jim Capron of the WNY Dairy and Field Crop Team), Cornell Crop and Soil Science personnel (Dr. William Cox and Mr. Dill Otis) and an industry representative (Mr. Donald Specker, Pioneer Hi-Bred International, Inc.) cooperated in this study, lending their variety trials for regular monitoring for soybean aphids. Locations for these trials were in the central and western soybean growing regions of the state: Aurora, Interlaken, Mt. Morris (Sonyea), and Waterloo.
