Other claims from this paper (9)
- Association The six rice cultivars had no effect on feeding and oviposition preferences of O. oryzae, indicating no antixenosis.
- Association Cultivars did not differ in egg viability and first-instar larval density on roots at 15 DAF.
- Association Larval density per sample of O. oryzae was high (up to 24.5) on BRS Pampa CL at 25 and 35 DAF.
- Association Larval density per sample was intermediate (up to 16.1) on BRS Querencia and BRS Ligeirinho.
- Association Larval density per sample was low (up to 8.8) on BRS Atalanta, BRS Firmeza and Dawn.
- Association BRS Atalanta, BRS Firmeza and Dawn caused malnutrition and inhibition of larval growth in O. oryzae.
- Association Emerged females had strongly decreased body weight on these cultivars.
- Association BRS Pampa CL, BRS Querencia and BRS Ligeirinho are susceptible, with high larval populations and more suitable O. oryzae development.
- Mechanism The authors conclude that antibiosis probably is the key mechanism of rice resistance to O. oryzae in BRS Atalanta, BRS Firmeza and Dawn.
