Bemisia tabaci; Tomato yellow leaf curl virus; crop production; farmers; global warming; governance; greenhouses; invasive species; models; questionnaires; risk; scientists; stakeholders; tomatoes; trade
Abstract:
... Because of global warming associated with increasing global trade, French productions are and will be increasingly subject to new bio-invasions. Thus, the emergence of the plant virus Tomato yellow leaf curl virus (TYLCV) and its vector Bemisia tabaci, an invasive species of whitefly of tropical origin, has destabilized the French sector of tomato production under greenhouses. Thanks to the Bemisi ...
