Other claims from this paper (9)
- Observation Neonate diamondback moth larvae moved after 72 hours.
- Observation Other diamondback moth instars moved within 24 hours.
- Intervention effect No larvae survived on pure transgenic canola by day six.
- Observation Few larvae survived on transgenic plants in mixtures.
- Association Adult emergence decreased as transgenic plant proportion increased.
- Intervention effect All four instars were killed when feeding only on transgenic plants.
- Mechanism Authors inferred that larval movement in seed mixtures increases resistance risk.
- Recommendation The authors advise against seed mixtures for slowing diamondback moth resistance.
- Recommendation The authors propose strip planting with wider row spacing to slow resistance.
