| dc.description.abstract | <jats:title>Abstract</jats:title><jats:p>The recent surge in sweet potato (<jats:italic>Ipomoea batatas</jats:italic>) cultivation in Europe prompted an investigation into associated entomofauna within Portugal's southwestern region, known for its longstanding sweet potato production. This study aimed to assess entomofauna associated with this culture.</jats:p><jats:p>Insect sampling was conducted by leaf and sweep net across three regional sites during 2018 and 2019 revealing the presence of <jats:italic>Empoasca fabalis</jats:italic>. Histological examination of sweet potato leaves affected by <jats:italic>E. fabalis</jats:italic> feeding unveiled significant damage, including the emergence of whitish spots (termed “stipples”) and subsequent necrotic spots. Comparative analysis between infested and undamaged control leaves revealed significant damage, involving mesophyll cell content deprivation and cellular disruption. This study describes, for the first time, the histological nature of the necrotic damage and suggests that <jats:italic>E. fabalis</jats:italic> primarily acts as a stippler on sweet potatoes, mainly targeting mesophyll cells with limited consumption of vascular tissue. The invasive behaviour and wide host range of <jats:italic>E. fabalis</jats:italic> pose a threat to sweet potato cultivation. These findings emphasize the need for monitoring to address the potential impact of <jats:italic>E. fabalis</jats:italic> on Europe’s agricultural ecosystem and native vegetation.</jats:p><jats:p>In addition, six other Auchenorrhyncha species were identified during this study, including four crucial vectors of plant diseases: <jats:italic>Laodelphax striatellus</jats:italic>, <jats:italic>Psammotettix alienus</jats:italic>, <jats:italic>Anaceratagallia glabra</jats:italic>, <jats:italic>Austroagallia sinuata</jats:italic>, together with <jats:italic>Empoasca solani</jats:italic> and <jats:italic>E. alsiosa</jats:italic>. These results emphasise the importance of managing these insects in sweet potato cultivation.</jats:p> | eng |
