Resumo: | A trial was carried out in Acreúna, Goiás State, Brazil, from March to April of 2002, to test the efficiency of insecticides to control Spodoptera frugiperda (J. E. Smith 1797) on cotton – cv. Delta Opal. The treatments applied and their respective doses of commercial product were: spinosad (75 mL.ha-1, 100 mL.ha-1, 125 mL.ha-1 and 150 mL.ha-1), methoxifenozide (500 mL.ha-1), clorpirifós (800 mL.ha-1), and control. In all of the treatments, except for control, it was added 2,0 L.ha-1 of vegetable oil. Six points (replications) were marked in the central row of each treatment strip, spaced about 100 m, around which evaluations were performed, counting the number of alive caterpillars in fifteen plants. The insecticides were sprayed two times at ten-day intervals. The countings were realized at there, five, seven, and ten days after the first application, and at three, five, seven, ten, and fourteen days after the second application. The treatments with spinosad at 100 mL.ha-1, 125 mL.ha-1 and 150 mL.ha-1 were efficient in controlling S. frugiperda on cotton up to seven days after treatment application. KEY-WORDS: Gossypium sp.; spinosad; clorpirifós; methoxifenozide. |

O trabalho foi conduzido em Acreúna, Goiás, Brasil, entre março e abril de 2002, com o objetivo de avaliar a eficiência de inseticidas no controle de Spodoptera frugiperda (J. E. Smith 1797), na cultura do algodoeiro – cv. Delta Opal. Os tratamentos inseticidas utilizados e as suas respectivas dosagens de produto comercial foram: spinosad (75 mL.ha-1, 100 mL.ha-1, 125 mL.ha-1 and 150 mL.ha-1), methoxifenozide (500 mL.ha-1), clorpirifós (800 mL.ha-1) e testemunha. Em todos os tratamentos, com exceção da testemunha, foi adicionado 2,0 L.ha-1 de óleo vegetal. Foram marcados seis pontos (repetições) na linha central de cada faixa de tratamento, distanciados cerca de 100 m, ao redor dos quais foram feitas as avaliações, contando-se o número de lagartas vivas em quinze plantas. Foram feitas duas aplicações para cada tratamento, com intervalo de dez dias. Foram realizadas contagens aos três, cinco, sete e dez dias após a primeira aplicação, e aos três, cinco, sete, dez e quatorze dias após a segunda aplicação. Os tratamentos com spinosad, nas dosagens de 100 mL.ha-1, 125 mL.ha-1 e 150 mL.ha-1 foram eficientes para o controle de S. frugiperda, na cultura do algodoeiro, até sete dias após a aplicação.
