Resumo: | The Plutella xylostella (L.) (Lepidoptera: Plutellidae) is a worldwide pest of Brassicaceae. Resistance has evolved against various insecticides including chlorfenapyr one of the most recently registered molecules to control this pest. The failure of chlorfenapyr to control this pest could be related to resistance in P. xylostella in the state of Pernambuco (Brazil), but there is currently no information on its heritability. Here, we estimated the heritability of resistance of P. xylostella to chlorfenapyr and the number of genes involved in the resistance in a field-derived population (PxClf-SEL). A field population was selected in the laboratory with increasing doses of chlorfenapyr (for five generations), and the LC50s were estimated for every generation using the leaf dip bioassay. The selection increased resistance to chlorfenapyr in the PxClf-SEL as the LC50 shifted from 27.6 (F1) to 256.5 (F5) mg chlorfenapyr/L. As a result, the resistance ratio (RR) increased from 33-fold (F1) to 310-fold (F5). The heritability of resistance of P. xylostella to chlorfenapyr was 0.90 (h2), and the number of generations needed for a 10-fold increase in the resistance to chlorfenapyr was 5.20 (G). Other methods have shown different numbers of genes (0.64 and 1.88) involved in resistance of P. xylostella to chlorfenapyr. There was sufficient variation regarding resistance in the field population to account for a high realized heritability influenced mainly by additive genetic factors. Therefore, there is a high risk of chlorfenapyr resistance in the field. |

A resistência tem evoluído para vários inseticidas incluindo clorfenapir, uma das moléculas registradas recentemente para o controle desta praga. As falhas de clorfenapir para controlar esta praga podem ser relacionadas com a resistência em P. xylostella no Estado de Pernambuco (Brasil), mas atualmente não há informações sobre sua herdabilidade. Aqui, foi estimada a herdabilidade da resistência de P. xylostella para clorfenapir e o número de genes envolvidos na resistência em uma população derivada do campo (PxClf-SEL). A população de campo foi selecionada no laboratório com doses crescentes de clorfenapir (por cinco gerações) e as CL50s foram estimadas para todas as gerações usando bioensaio de imersão de folha. A seleção aumentou a resistência para clorfenapir na PxClf-SEL, como também deslocou a CL50 de 27,60 (F1) para 256,50 (F5) mg de clorfenapir/L. Como resultado, a razão de resistência (RR) aumentou de 33 (F1) para 310 vezes (F5). A herdabilidade da resistência de P. xylostella para clorfenapir foi 0,90 (h2) e o número de gerações necessário para aumentar em 10 vezes a resistência foi 5,20 (G). Outros métodos tem mostrado diferente número de genes (0,64 e 1,88) envolvidos na resistência de P. xylostella para clorfenapir. Houve variação suficiente na população de campo em relação à resistência para justificar a alta herdabilidade, influenciada principalmente por fatores genéticos aditivos. Portanto, existe um alto risco de resistência no campo.Universidade Federal Rural do Semi-Árido2017-06-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/594310.1590/1983-21252017v30n428rcREVISTA CAATINGA; Vol. 30 No. 4 (2017); 1067-1072Revista Caatinga; v. 30 n. 4 (2017); 1067-10721983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5943/pdfLima Neto, Jaconias EscócioSiqueira, Herbert Álvaro Abreu deinfo:eu-repo/semantics/openAccess2023-07-20T11:38:07Zoai:ojs.periodicos.ufersa.edu.br:article/5943Revistahttps://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:2024-04-29T09:46:25.462014Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
