Abstract

The apple maggot, Rhagoletis pomonella (Walsh), was monitored with baited yellow panels and red spheres in commercial orchards, abandoned orchards, and unsprayed backyard apple trees in 1998 and 1999. Apple maggot adults were captured in all apple habitats, but the capture levels in the abandoned orchards and unsprayed backyard trees tended to be higher than in the commercial orchards. Peak capture occurred between mid-July and late August in both years. Emergence cages seeded with infested fruits were used to investigate bivoltinism, which was observed in both years.
