Resumo: | Tobacco production in Brazil is an essential source of income for many families, especially in the southern region. However, it is subject to attack by pests and diseases, such as the fungus gnats insect. To control this pest, the mite Stratiolaelaps scimitus is found in Brazilian soil, which has a predatory potential to fungus gnats. This study aimed to evaluate the use of S. scimitus as an insect control agent, compared to chemical control, in the production of tobacco seedlings in the floating system. The experiment was carried out on a farm in Crissiumal-RS, in a randomized block design, with four replications: T1= control, T2= chemical control based on Imidacloprid and Azadirachtin, and T3= S. scimitus. To analyze the control efficiency, adult insects were captured at different times, and the biological control did not differ from the chemical control. The biological treatment made it possible to reduce the use of chemical products. Concomitantly, questionnaires verified that producers are well accepting the new control model. Therefore, using S. scimitus could reduce the proliferation of fungus gnats in the production of tobacco seedlings in the floating system, but more studies need to be carried out for a better evaluation. |

No entanto, está sujeita ao ataque de pragas e doenças, como o inseto fungus gnats. Como alternativas ao controle dessa praga, encontra-se no solo brasileiro o ácaro Stratiolaelaps scimitus, que apresenta potencial predatório ao fungus gnats. O objetivo desse estudo foi avaliar o uso do S. scimitus como agente de controle do inseto, comparado ao químico, na produção de mudas de tabaco no sistema floating. O experimento foi conduzido em uma propriedade rural no município de Crissiumal-RS, em delineamento em blocos ao acaso, com quatro repetições: T1= controle, T2= químico a base de Imidacloprido e Azadiractina e T3= S. scimitus. Para análise da eficiência de controle, foram realizadas capturas de insetos adultos em diferentes épocas, e o controle biológico não diferiu do controle químico. O tratamento biológico possibilitou redução no uso de produtos químicos. De forma concomitante, verificou-se por meio de questionários, que o novo modelo de controle está sendo bem aceito pelos produtores. Portanto, a utilização de S. scimitus foi capaz de reduzir a proliferação de fungus gnats na produção de mudas de tabaco no sistema floating, porém mais estudos precisam ser realizados para melhor avaliação.Universidade Federal Rural do Semi-Árido2023-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1066410.1590/1983-21252023v36n223rcREVISTA CAATINGA; Vol. 36 No. 2 (2023); 464-470Revista Caatinga; v. 36 n. 2 (2023); 464-4701983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10664/11155Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccess Mazzutti, MarcioBisognin, Ramiro Pereira Guerra, Divanilde Bohrer, Robson Evaldo GehlenSilva, Danni Maisa daSouza , Eduardo Lorensi de2023-07-27T12:05:37Zoai:ojs.periodicos.ufersa.edu.br:article/10664Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:57.867157Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
