Other claims from this paper (12)
- Observation Cry1Ac was most toxic to Heliothis virescens and Pectinophora gossypiella in diet bioassays.
- Observation Cry1Ac had good activity against Helicoverpa zea.
- Observation Cry2Ab2 was most toxic to P. gossypiella and least toxic to S. frugiperda.
- Observation Cry2Ab2 was more toxic than Cry1Ac to S. exigua and S. frugiperda.
- Observation P. gossypiella was three-fold less sensitive to Cry2Ab2 than Cry1Ac.
- Observation H. virescens was 40-fold less sensitive to Cry2Ab2 than Cry1Ac.
- Intervention effect Cry1Ac/Cry2Ab2 cotton caused at least 90% H. zea larval mortality after five days on excised squares, versus 30-80% for Cry1Ac-only cotton.
- Intervention effect Cry1Ac/Cry2Ab2 cotton leaf discs caused 69 to 93% S. frugiperda second-instar mortality, versus 20-69% for Cry1Ac-only cotton.
- Observation Flower abortion after H. zea infestation was 15%, 41%, and 63% for Cry1Ac-only cotton after prior larval feeding for 0, 24, or 48 h.
- Observation Flower abortion after H. zea infestation was 0%, 0%, and 5% for Cry1Ac/Cry2Ab2 cotton after prior larval feeding for 0, 24, or 48 h.
- Observation Terminal leaves had the highest Cry1Ac concentration, while large leaves, calyx, and bracts had the lowest.
- Observation Ovules had the highest Cry2Ab2 concentration, while terminal leaves, large leaves, bracts, and calyx had the lowest.
