Resumo: The fall armyworm Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) is a major pest of corn in Brazil, requiring a high cost control measures. The objective of this study was to determine the effectiveness of insecticides applied in seed treatment and foliar sprays of corn in insect control. Two experiments were conducted, 2009/10 and 2010/11 seasons in a randomized block design with four replications. In 2009/10 were studied: imidaclo- prid (ST), thiamethoxam (ST), imidacloprid + betacyfluthrin (FS), lambdacyalothrin + thiamethoxam (FS), carbofuran (ST), lufenuron (FS). In 2010/11 were studied: flubendiamide (FS), betacyfluthrin + imidacloprid (FS), deltamethrin (FS), lambdacyalothrin + thiamethoxam (FS), cypermethrin (FS), lufenuron (FS), spinosad (FS), imidacloprid (ST), imidacloprid + thiodicarb (ST). The insecticides imidacloprid (400 mL 100kg–1) and thiamethoxam seed applied to mai- ze seedlings protected from attack by caterpillars up to 10 days after emergence, whereas flubendiamide insecticides, cypermethrin and lufenuron conditioned and a lower rate of damaged plants.

A lagarta-do-cartucho Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) é a principal praga do milho no Brasil e demanda elevados custos com controle. O objetivo deste trabalho foi determinar a eficiência de inseticidas aplicados via sementes e via foliar no controle de S. frugiperda na cultura do milho. Realizaram-se dois experimentos, safras 2009/10 e 2010/11, em delineamento de blocos casualizados com quatro repetições. Na safra 2009/10 foram avaliados os inseticidas imidacloprido (TS), tiametoxam (TS), imidacloprido + betaciflutrina (PF), lam- bdacialotrina + tiametoxam (PF), carbofurano (TS), lufenuron (PF). Em 2010/11 foram avaliados: flubendiamida (PF), imidacloprido + betaciflutrina (PF), deltametrina (PF), lambdacialotrina + tiametoxam (PF), cipermetrina (PF), lufenuron (PF), espinosade (PF), imidacloprido (TS) e imidacloprido + tiodicarbe (TS). Os resultados evidenciaram que o trata- mento de sementes com imidacloprido (400 mL p.c. 100 kg–1) e tiametoxam (600 mL p.c. 100 kg–1) protege as plântulas de milho do ataque de lagartas até 10 dias pós-emergência, enquanto o tratamento foliar com flubendiamida (100 mL ha–1), lufenuron (300 mL p.c. ha–1) e cipermetrina (100 mL p.c. ha–1) proporciona menor índice de plantas danificadas.
