Fig. 8. The normal flow of increase of population of aphids with time was severely affected when observed after 40 d on the transgenic plant line expressing ACA lectin peptide, when compared to the increase of aphid population after 40 d on the untransformed plant. The figure documents that the number of aphids colonizing on the transgenic plant, ACA# 8 had shown an initial increase until the d 20, but ceased to increase further. On the contrary, the number of aphids infesting the untransformed plant has shown rapid increase with passage of time. The ( line indicates insects on untransformed PCR7 plant and the line indicates insects on transgenic ACA#8 plant.
