Abstract(s)
As cigarrinhas-verdes (Hemiptera, Cicadellidae) são uma praga de grande importância nas vinhas do Alentejo, particularmente a espécie
Jacobiasca lybica. São raros os estudos que envolvem a opinião dos viticultores sobre os problemas com os quais se deparam no combate
às cigarrinhas, pelo que este estudo tem como objetivo conhecer as perceções dos viticultores relativamente à importância das cigarrinhas
verdes no Alentejo, os respetivos fatores de nocividade e o processo de tomada de decisão no combate a esta praga. Com este objetivo, foi
elaborado um inquérito com resposta online pelos viticultores da região do Alentejo. O questionário foi dividido nas seguintes secções:
caracterização da exploração; importância das cigarrinhas-verdes na vinha; estratégias de proteção da vinha contra as cigarrinhas-verdes
incluindo tratamentos fitossanitários; caracterização do inquirido. Procedeu-se a uma análise descritiva para sistematização dos resultados.
De acordo com as respostas dos viticultores, as cigarrinhas-verdes são consideradas pragas-chave na região do Alentejo, particularmente
nas explorações com maior área de vinha. A proteção química com recurso a produtos de síntese continua a ser o meio de proteção mais
utilizado.
Grapevine leafhoppers (Hemiptera, Cicadellidae) are an important pest in Alentejo’s vineyards. The importance of these insects has been increasing in the region, particularly the species Jacobiasca lybica. Studies involving the opinion of winegrowers on the pest management related to leafhoppers are scarce. This work was aimed at understanding the perception of Alentejo’s winegrowers relative to greenleafhoppers pest management. Therefore, an online survey was carried out to a sample of winegrowers. The questionnaire was divided in the following sections: farm characterization; grapevine leafhopper pest status; vine protection strategies against these leafhoppers including phytosanitary treatments; characterization of the winegrowers inquired. A descriptive analysis of the results was conducted. According to the surveyed winegrowers, green grapevine leafhoppers are considered key pests in Alentejo, especially in larger vineyard areas. Chemical control is still the most common pest management tactic used against this insect pest in the region.
