Resumo: | Outbreaks of Myzus persicae (Sulzer) (Hemiptera: Aphididae) populations are not rare in Brassica crops in Pernambuco State (Brazil). The aim of the present study was to perform laboratory assessments in seven insecticide formulations against M. persicae. The direct spray and leaf dip methods were used in the experiment. M. persicae mortality rates were subjected to variance and Probit analyses. Based on the results, thiamethoxam + lambda-cyhalothrin, thiamethoxam, lambda-cyhalothrin and thiamethoxam + chlorantraniliprole were the most efficient insecticides after 24-hour exposure, since they caused over 95% mortality through the direct spray method. LC50s ranged from 0.10 to 9.1 mg a.i./L in chlorfenapyr and chlorantraniliprole, respectively, in the leaf dip method. All insecticides were effective against M. persicae, except for chlorantraniliprole. Chlorfenapyr, lambda-cyhalothrin, pymetrozine and thiamethoxam + lambda-cyhalothrin were the most toxic to this aphid. |

O objetivo desse estudo foi realizar avaliação laboratorial de sete formulações de inseticidas contra M. persicae. Para tanto, foram utilizados o método de pulverização direta e o método de imersão de folha. A mortalidade de M. persicae foi submetida à análise de variância e análise de Probit. Os resultados mostraram que após 24 horas de exposição, tiametoxam + lambda-cialotrina, tiametoxam, lambda-cialotrina e tiametoxam + clorantraniliprole foram mais eficientes, causando mortalidade acima de 95% pelo método de pulverização direta. Utilizando o método de imersão de folha, as CL50s foram de 0,10 até 9,1 mg i.a/L para clorfenapir e clorantraniliprole, respectivamente. Com exceção ao clorantraniliprole, todos os inseticidas foram eficazes para M. persicae sendo que clorfenapir, lambda-cyhalothrin, pimetrozina e tiametoxam + lambda-cialotrina foram mais tóxicos para o afídio.
