Table 5. Two-way repeated-measures ANOVA results for abundance of non-target arthropods with values weights greater than 0.5 and less -0.5 in the Principal Response Curves (PRC) analysis with first axis significant collected by Pitfall traps in non-Bt (with and without insecticides) and Bt (DAS-81419-2) soybean fields at two sites over two to three years in Brazil.

P-values highlighted in bold are statistically significant (α = 0.05).

Degrees of freedom: soybean fields = 2; sampling time = 3; interaction = 6; residual = 12.

Means (± SE) followed by different letters were significantly different within rows (Tukey’s test, α = 0.05).
