The overallobjective of this investigation was to look for new control strategy through evaluate the effects of the application of hydrophobic nano-silica on the resistance of tomato plants to this pest. The experiments were carried out under semi field conditions; the experiment was conducted with two treatments, consisting of nano-silica application, and a negative control (distilled water) with five replications. Nano-silica
