Fig. 15From: Effect of herbivore stress on transgene behaviour in maize crosses with different genetic backgrounds: cry1Ab transgene transcription, insecticidal protein expression and bioactivity against insect pestsSpearman’s rank correlation coefficient (Rs) between the mortality rate (%) of S. littoralis larvae and Cry1Ab concentration (µg/g dwt) in damaged and undamaged plants across different genetic backgrounds from South Africa. The feeding damage was induced by S. littoralis larvae. Damaged maize plants (Rs = 0.22, P = 0.07); undamaged maize plants (Rs = 0.19, P = 0.12)Back to article page
