Field Tests of Synthetic Apple Volatiles as Apple Maggot (Diptera: Tephritidae) Attractants1

Abstract

In field tests in abandoned and commercial orchards in New York, sticky-red spheres baited with a blend of synthetic apple volatiles captured significantly more male and female apple maggot flies, Rhagoletis pomonella (Walsh), than unbaited spheres. Polyethylene caps loaded with 50 and 100 mg of the blend were more effective than those containing 300 mg. The volatiles did not increase the effectiveness of sticky-yellow panels (Pherocon AM) during early-season tests.
