Other claims from this paper (15)
- Observation Ericaphis fimbriata was the principal aphid.
- Association Primary parasitoid frequencies varied significantly by geographical area.
- Observation Praon unicum dominated in southwestern British Columbia.
- Observation Aphidius n. sp. dominated west of the Cascades.
- Observation A. sp. and A. ervi dominated east of the Cascades.
- Observation Pteromalids dominated secondary parasitoids.
- Observation Relative pteromalid frequency was lowest in southwestern British Columbia.
- Observation Praon unicum parasitization increased to 0.080 ± 0.024 in late July or early August.
- Observation A. n. sp. parasitization increased to 0.090 ± 0.084 in late July or early August.
- Observation Praon unicum emerged four weeks before A. n. sp.
- Observation Praon unicum parasitization was lower in conventional than organic fields.
- Observation Aphid density rose monotonically.
- Observation Praon unicum had two spring peaks.
- Observation A simulation indicated the two spring peaks could reflect discrete generations.
- Recommendation The authors suggested releasing P. unicum at 150 or 450 DD above 5.6 °C to augment spring populations.
