Mortality and pupation rate of H. armigera and S. litura larvae feeding on SaPIN2a-overexpressing and control tobacco plants. Ten early second-instar larvae were introduced to each plant of transgenic lines and wild-type plants (WT). Three plants of each transgenic line and WT were used for insect feeding bioassays.

|---|---|---|---|---|
| H. armigera | S. litura | H. armigera | S. litura | |
| WT | 16.7 ± 3.3 | 43.3 ± 3.3 | 83.8 ± 4.4 | 82.2 ± 1.1 |
