FIGURE 4 . Multinomial distribution with occurrence rate ofA. gossypii in the regions of non-Bt and Bt cotton plants at
infestation times of 0 h, 24, 48 and 72 h with densities of 30 and 60
aphid/cotton plants. The red circle diameter represents the intensity of
aphid infestation on cotton plants.
TABLE 1 - Number of variation potentials emitted (mean ± SE) by
Bt and non-Bt cotton plants when subjected to different exposure times
and densities of A. gossypii /plant.
