with thiamethoxam and pyrethroids, and densities in cuts treated
with foliar pyrethroids and chlorantraniliprole also did not significantly
differ. However, chlorantraniliprole seed treatment provided
significantly (P < 0.05) better control of L. oryzophilus than
did thiamethoxam seed treatment (Table 2). In 2011, when only
seed treatments were evaluated, a significant (P < 0.05) difference
was detected between untreated and treated plots. Significant
differences in densities of L. oryzophilus were not observed in plots
treated with the two neonicotinoids (thiamethoxam and clothianidin),
but densities in neonicotinoid-treated plots were lower than
untreated plots. Plots treated with chlorantraniliprole showed the
lowest densities of L. oryzophilus larvae and pupae (Table 2).
