Other claims from this paper (8)
- Observation Crataegus holmesiana was the primary hawthorn host of Rhagoletis pomonella in surveyed western New York.
- Observation Peak fly captures in hawthorn trees occurred in the first week of August.
- Observation Reciprocal crosses of apple and hawthorn flies produced equally viable eggs.
- Observation Hawthorn fruits sampled in August frequently contained more than one fly egg.
- Observation In laboratory tests, flies preferred apples for oviposition over hawthorn fruit until the final week of August regardless of host origin.
- Observation After the final week of August, flies from both origins preferred hawthorn fruit for oviposition.
- Observation Field observations indicated flies associated with either host would oviposit in both fruits when available.
- Recommendation The authors considered hawthorn-associated R. pomonella potential pests of commercial apple orchards in New York.
