Resumo: | The Plutella xylostella is a recurring pest on cruciferous crops around the world. The susceptibility of diamondback moth populations to the insecticides abamectin, deltamethrin, and spinosad, from three Brazilian regions was compared through collard leaf dipping bioassays in laboratory for the different treatments. Mortality data were assessed 48 hours after exposition to every insecticide and submitted to Probit analysis. All the populations showed significant resistance to at least one of the insecticides. The Bonito-PE population showed the highest resistance ratio (20.2 times) to abamectin when compared with the susceptible population and to other insecticides. The deltamethrin LC50s were very high for all the populations tested, ranging from 85.2 to 360.1 mg/L. All the populations from Pernambuco State were considered resistant to deltamethrin, with resistance ratios varying from 2.2 to 4.2 times. Five populations showed significant resistance to spinosad with ratios varying from 2.3 to 5.1. These results are discussed based on the spectrum of insecticides used in the regions. In conclusion, the need of resistance toinsecticides management programs for P. xylostella in conjunction with an integrated pest management is urgent in these regions. |

A suscetibilidade de populações de traça-das-crucíferas aos inseticidas abamectina, deltametrina e espinosade, provenientes de três regiões brasileiras, foram comparadas através de bioensaios com imersão de folhas de couve. A mortalidade foi avaliada após 48 horas de exposição aos inseticidas e os dados foram submetidos à análise de Probit. Os resultados demonstraram que sete populações de traça-das-crucíferas apresentaram significativa resistência a um ou mais inseticidas. A população de Bonito-PE apresentou a maior razão de toxicidade (20,2 vezes) ao abamectina quando comparados com a população suscetível. As CL50s para deltametrina foram altas para as populações de traça-das-crucíferas, variando de 85,2 a 360,1 mg/L do inseticida. Todas as populações do Estado de Pernambuco foram consideradas resistentes ao deltametrina, apresentando razões de toxicidade variando entre 2,2 e 4,2 vezes. Cinco populações apresentaram moderada resistência ao espinosade com níveis de resistência variando de 2,3 a 5,1. Assim, a necessidade de desenvolvimento de programas de manejo de resistência de P. xylostella a inseticidas associados ao manejo integrado de pragas torna-se evidente nestas regiões produtoras de brássicas.Submitted by (edna.saturno@ufrpe.br) on 2016-11-22T16:29:59Z No. of bitstreams: 1 Alexandre Conte de Oliveira.pdf: 285466 bytes, checksum: dde44764fcdc48d6862c5cda4477617c (MD5)Made available in DSpace on 2016-11-22T16:29:59Z (GMT).

The Plutella xylostella is a recurring pest on cruciferous crops around the world. The susceptibility of diamondback moth populations to the insecticides abamectin, deltamethrin, and spinosad, from three Brazilian regions was compared through collard leaf dipping bioassays in laboratory for the different treatments. Mortality data were assessed 48 hours after exposition to every insecticide and submitted to Probit analysis. All the populations showed significant resistance to at least one of the insecticides. The Bonito-PE population showed the highest resistance ratio (20.2 times) to abamectin when compared with the susceptible population and to other insecticides. The deltamethrin LC50s were very high for all the populations tested, ranging from 85.2 to 360.1 mg/L. All the populations from Pernambuco State were considered resistant to deltamethrin, with resistance ratios varying from 2.2 to 4.2 times. Five populations showed significant resistance to spinosad with ratios varying from 2.3 to 5.1. These results are discussed based on the spectrum of insecticides used in the regions. In conclusion, the need of resistance toinsecticides management programs for P. xylostella in conjunction with an integrated pest management is urgent in these regions. |
