Fig. 1. Principal component (PC) plot of the nematode communities under maize at the mature stage. Data points represent the mean of five replicates; bars are the least significant difference (p < 0.05). Symbols for Foulum soil are open and for Varois soil are filled, and are: Bt maize = diamond; non-Bt maize = triangle; Bt maize + insecticide = square; non-Bt maize + insecticide = circle.
