Insect bioassay performed on Bt-transgenic tomato lines of T 4 generation with 2nd instar larvae of S. litura and H. armigera . A Tomato plants grown under contained glasshouse 1– non-transgenic plant as control, 2– Ab25 A, 3– Ab25 D and 4– Ab25 E transgenic plants. B Insect bioassay assay performed with S. litura on detached leaves of tomato plants documented after 48 h of feeding. 1– leaf of control plant without insect infestation, 2– leaf of control plant, 3– Ab25 A, 4– Ab25 D and 5– Ab25 E lines challenged with S. litura respectively showing significant damages to the control leaf compared to the transgenic leaves. C Insect assay performed with H. armigera on tomato fruits documented after 96 h of feeding, 1–non-transgenic tomato as control without insect infestation, 2–control tomato, 3–Ab25 A, 4–Ab25 D and 5–Ab25 E lines challenged with insect respectively showing significant damages to the control tomato compared to the transgenic tomato.
