Resumo: | Experiments were conducted at the Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS) at Sete Lagoas, MG, Brazil, to study the biology and potential of Doru luteipes (Scudder, 1876) as a predator of Spodoptera frugiperda (J.E. Smith, 1797) eggs and larvae, under laboratory conditions. Field experiments were conducted to determine the effect of several insecticides on the predator. In the biological studies, it was observed that D. luteipes produced an average of 26.6 eggs per oviposition and that the incubation period was 7.31 days. The nymphal stage varied from 37.1 to 50.1 days according to the diet used. The average adults stage ranged from 83.2 to 143 days when fed with a diet of eggs or larvae, respectively. This study indicated that this insect has a good potential as a predator of S. frugiperda. In the nymphal stage the daily consumption was 12, 10 and 8 larvae when consumed alone, with corn leaves and with a diet, respectively. In the adult stage the daily consumption was, in the same order as above, 21, 19 and 10 larvae. Among the insecticides tested in field experiments, permethrin, deltamethrin and methomyl were efficient in controlling S. frugiperda and did not affect the predator D. luteipes. Based on the results, it was concluded that D. luteipes under laboratory conditions gave an efficient control of S. frugiperda (eggs and larvae) and can be used under field conditions as for controlling this important pest of corn. |

O trabalho foi realizado no Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS), em Sete Lagoas, MG, tendo como objetivo conhecer a biologia e o potencial de Doru luteipes (Scudder, 1876) como predador de ovos e larvas de Spodoptera frugiperda (J.E. Smith, 1797), em condições de laboratório. Estudou-se também, em condições de campo, o efeito de diversos inseticidas sobre o predador. Dos estudos bioecológicos, observou-se que as posturas possuem, em média, 26,6 ovos, e o período de incubação é de 7,31 dias. A fase ninfal variou de 37,1 a 50,1 dias, conforme o tratamento, e a fase adulta, de 83,2 dias para indivíduos alimentados com ovos, a 143 dias para indivíduos alimentados com larvas. O inseto mostrou um bom potencial como predador de S. frugiperda, apresentando um consumo diário na fase ninfal de 12, 10 e 8 larvas, conforme estas foram oferecidas isoladamente, com folhas de milho ou com dieta. Na fase adulta, o consumo foi na mesma sequência da anterior, de 21, 19 e 10 larvas. Com relação aos inseticidas testados, os produtos permethrin, deltamethrin e methomyl foram eficientes no controle de S. frugiperda, e praticamente não afetaram o predador. Com base nos resultados, concluiu-se que D. luteipes, em condições de laboratório, apresentou-se eficiente no controle de S. frugiperda e possui grande potencial para utilização no controle deste inseto em milho, em condições de campo.
