AB BACKGROUND: The use of zoophytophagous predators in protected crops has been widely adopted to manage pests in southernEurope. We hypothesized that plant defence responses would be induced by zoophytophagous predators and this inductioncould affect plant virus occurrence; the phytophagy of these predators induces plant defences similarly to that of viral infection.Therefore, we evaluated whether or not mirid predator-activated plant defences limited the accumulation ofTomato SpottedWilt Virus(TSWV) in mechanically infected sweet pepper.RESULTS: Our results revealed TSWV accumulation in mirid-punctured plants to be significantly lower than in intact plants. Thisis most likely associated with the upregulation of the jasmonate acid pathway triggered by mirid phytophagy.CONCLUSION: Activation of induced defences by mirid predators has been demonstrated for the first time to limit theaccumulation of TSWV in sweet pepper. This novel approach can offer new control strategies for the management of plantdiseases.
