Other claims from this paper (7)
- Observation Parasitism of Smicronyx fulvus larvae by Triaspis aequoris in cultivated sunflower ranged from 0.0 to 23.2%.
- Observation Parasitism of Smicronyx fulvus larvae by Triaspis aequoris in wild Helianthus annuus ranged from 0.0 to 25.0%.
- Association Planting date had significant but inconsistent effects on parasitism in sunflower.
- Association Smicronyx larvae from wild H. annuus tended to have lower mass than those from cultivated sunflowers.
- Observation Triaspis aequoris was the only parasitoid reared from Smicronyx spp. collected in cultivated sunflowers.
- Mechanism Wild H. annuus may serve as an insecticide-free refuge for Triaspis aequoris.
- Method / resource The DNA-based method is more reliable than the emergence-based method for assessing parasitism by Triaspis aequoris.
