Resumo
A introdução de pragas agrícolas em um país representa um risco para a agricultura, podendo causar danos ao meio ambiente, à economia, perdas de mercados e custos elevados em programas de controle. Portanto, é estratégico que um país que tem na agricultura o principal pilar de sua economia, como é o caso do Brasil, disponha de meios para identificar precocemente os eventos de invasão, os quais incluem o conhecimento sobre as espécies e metodologias para priorizar aquelas de maior potencial de risco. A recente declaração de estado de emergência fitossanitária deflagrado pelos prejuízos bilionários causados por Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) colocou os produtores de grandes culturas em alerta para a possibilidade de que outras espécies de comportamento semelhante possam ser introduzidas no Brasil. Assim, o objetivo desse estudo foi avaliar de forma qualitativa e com base no roteiro preconizado pelo Comitê de Sanidade Vegetal do Cone Sul (Cosave) para análise de risco de pragas, o risco representado para o Brasil por espécies quarentenárias e não quarentenárias de Noctuidae (Lepidoptera) com relevância para as culturas de soja, milho e algodão em outras partes do mundo. As espécies foram levantadas por meio de revisão bibliográfica e consultas a bases de metadados internacionais. As espécies estudadas foram: Agrotis segetum (Denis & Schiffermüller, 1775), Autographa gamma (Linnaeus, 1758), Busseola fusca (Fuller, 1901), Chrysodeixis chalcites (Esper, 1789); Diparopsis castanea (Hampson, 1902); Diparopsis watersi (Rothschild, 1901), Earias biplaga (Walker, 1866), Earias insulana (Boisduval, 1833), Hadula trifolii (Hufnagel, 1766), Helicoverpa punctigera Wallengren, 1860, Heliothis viriplaca (Hufnagel, 1766), Mamestra brassicae (Linnaeus, 1758), Mythimna loreyi (Duponchel, 1827), Mythimna separata Walker, 1865, Sesamia calamistis (Hampson, 1910), Sesamia cretica (Lederer, 1857), Sesamia inferens (Walker, 1856), Spodoptera littoralis (Boisduval, 1833), Spodoptera exempta (Walker, 1857), Spodoptera litura (Fabricius, 1775), Spodoptera mauritia (Boisduval, 1833), Spodoptera praefica (Grote, 1875), Xestia c-nigrum (Linnaeus, 1758). As espécies de maior potencial de risco para o Brasil são: A. gamma, H. punctigera, A. segetum, S. exemptae S. littoralis.
The introduction of plant agricultural pests in a country represents a threat to agriculture as it may lead to environmental impact, economic losses, reduction in access to foreign markets and increased management costs. Thus, a country that largely relies on agriculture, should count on the strategic support of tools to identify early invasion events. These tools may include, for instance, a detailed knowledge of pests and the development of pest categorization so as to identify those that are more likely to become established and cause damage. The recent declaration of phytosanitary emergence due to the bilionary losses due to Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) introduction increased grower awareness to the possibility of introduction of similar species. This work aims to evaluate qualitatively and based on the framework provided by the Comitê de Sanidade Vegetal do Cone Sul (Cosave) for pest risk analysis, the risk posed by regulated and non regulated noctuid (Lepidoptera) species that attack soybean, corn and cotton in other parts of the world. Species were surveyed in the scientific literature and online international databases. The following species were analysed: Agrotis segetum (Denis & Schiffermüller, 1775), Autographa gamma (Linnaeus, 1758), Busseola fusca (Fuller, 1901), Chrysodeixis chalcites (Esper, 1789), Diparopsis castanea (Hampson, 1902), Diparopsis watersi (Rothschild, 1901), Earias biplaga (Walker, 1866), Earias insulana (Boisduval, 1833), Hadula trifolii (Hufnagel, 1766), Helicoverpa punctigera Wallengren, 1860, Heliothis viriplaca (Hufnagel, 1766), Mamestra brassicae (Linnaeus, 1758), Mythimna loreyi (Duponchel, 1827), Mythimna separata Walker, 1865, Sesamia calamistis (Hampson, 1910), Sesamia cretica (Lederer, 1857), Sesamia inferens (Walker, 1856), Spodoptera littoralis (Boisduval, 1833), Spodoptera exempta (Walker, 1857), Spodoptera litura (Fabricius, 1775), Spodoptera mauritia (Boisduval, 1833), Spodoptera praefica (Grote, 1875), Xestia c-nigrum (Linnaeus, 1758). A. gamma, H. punctigera, A. segetum, S. exemptae S. littoralis were categorized as the ones that represent the highest risk for Brazil.
