Electrical signalling on Bt and non-Bt cotton plants under stress by Aphis gossypii
Fig 2
Boxplot of time (h) of exposure of Bt and non-Bt cotton plants to different densities of A. gossypii emitting potentials of variation (VPs) (mV).
Bt and non-Bt cotton plants were infested at densities of 30 and 60 aphids/plant and in the absence of aphids (Control). Circle within the boxplot corresponds to mean of time for each treatment.
