Primary hosts of T. evansi are solanaceous crops such as tomatoes, potatoes, snuff, etc. mites puncture the leaves during feeding, causing yellowing or bleaching of leaves. Then the leaves are falling and in the case of severe attack the plant dies. The research study showed that Sarmento T. evansi manipulate host defenses by suppressing the induction of salicylic acid and jasmonic acid signaling pathways involved in defense mechanisms of plants in tomato plants. Salicylic acid and jasmonic acid play a crucial role in immunity of plants. Mites reduce the amount of inducible defense compounds and volatile substances (eg, protease inhibitors), which play a crucial role in plant defense. Control of pathogens affecting these crops is an important area of research. The result of research by Sarmento allows a better understanding of plant-herbivore interactions. Opens the door to new research in two directions:
* Biological control of Tetranychus evansi at an affordable price to the farmer.
* Development of varieties in a position to fight against the manipulations of herbivores.
