Resumo: | The objective of this research was to evaluate the efficiency of strains IBCB 425, 348 IBCB, UFGD 22 and UFGD 28 of Metarhizium anisopliae to control Mahanarva fimbriolata, in the culture of sugar cane, in field conditions. The experimental design was a randomized block with five treatments and four replications. Were applied 2 Kg ha-1 of rice + fungus sporulated with a concentration of 1.0 × 10 ¹² viable conidia ha-1. Evaluations were performed at 15, 30, 60, 90, 120 days after application, noting the number of nymphs and adults live, infected and killed not parasitized. It was found that within fifteen days of the treatments were infected insects. There was greater efficiency for IBCB 425 with 72.2% for nymphs and 83.3% for adults. The isolate UFGD 28 promoted the lowest number of nymphs per linear meter (3.7), with an efficiency of 66.3%. In the treatment with the application of the IBCB 425 isolate, 0.7 adults per linear meter and 70.0% efficiency were found, 60 days after spraying. The density of nymphs and adults decreased, 120 days after spraying, remaining below the economic injury level (four nymphs/meter), due to low rainfall in the period. The isolated UFGD 22 had the lowest population of nymphs (1.5) and adults (0.8) per meter, with control efficiency of 85.94 and 75.0% for nymphs and adults, respectively. The isolated IBCB 425 has outperformed causing, on average, 97.98% parasitism for nymphs and 91.3% parasitism for adults, demonstrating the residual power, within 120 days of application. |

El diseño experimental fue bloques al azar con cinco tratamientos y cuatro repeticiones. Se aplicaron 2 kg ha-1 de arroz + hongo esporulado con una concentración de 1.0 × 10¹² con ha-1 viable. Las evaluaciones se realizaron a los 15, 30, 60, 90, 120 días después de la aplicación, observando el número de ninfas y adultos vivos, parasitados y no parasitados muertos. Se encontró que 15 días después de la aplicación de los tratamientos, se encontraron insectos infectados. Se observó una mayor eficiencia para el IBCB 425 con 72.2% para ninfas y 83.3% para adultos. El número más bajo de ninfas por metro lineal (3.7) ocurrió con el aislado UFGD 28, con una eficiencia del 66.3% y con el aislado IBCB 425, se encontraron 0.7 adultos por metro lineal y 70.0% de eficiencia, 60 días después de la pulverización. La densidad de población de ninfas y adultos disminuyó, 120 días después de la pulverización, estando por debajo del nivel de daño económico (4 ninfas / metro lineal), debido a la baja precipitación que se produjo en el período. El aislado UFGD 28 promovió el menor número de ninfas por metro lineal (3.7), con una eficiencia del 66.3%. En el tratamiento con la aplicación del aislado IBCB 425, se encontraron 0.7 adultos por metro lineal y 70.0% de eficiencia, 60 días después de la pulverización.. El aislado IBCB 425 fue más efectivo, causando, en promedio, 97.9% de parasitismo para ninfas y 91.3% de parasitismo para adultos, lo que demuestra la potencia residual, después de 120 días de aplicación.O objetivo desta pesquisa foi avaliar a eficiência dos isolados IBCB 425, IBCB 348, UFGD 22 e UFGD 28 de Metarhizium anisopliae para o controle de Mahanarva fimbriolata, na cultura da cana de açúcar, em condições de campo. O delineamento experimental foi por blocos casualizados com cinco tratamentos e quatro repetições. Foram aplicados 2 Kg ha-1 de arroz + fungo esporulado com concentração de 1,0 × 10¹² com viáveis ha-1. As avaliações foram realizadas aos 15, 30, 60, 90, 120 dias após a aplicação, observando-se o número de ninfas e adultos vivos, parasitados e mortos não parasitados. Verificou-se que decorridos 15 dias da aplicação dos tratamentos encontravam-se insetos infectados. Observou-se maior eficiência para o IBCB 425 com 72,2% para ninfas e de 83,3% para adultos. O isolado UFGD 28 promoveu o menor número de ninfas por metro linear (3,7), com eficiência de 66,3%. No tratamento com aplicação do isolado IBCB 425 foi encontrado 0,7 adulto por metro linear e 70,0% de eficiência, 60 dias após a pulverização. A densidade populacional de ninfas e adultos diminuíram, 120 dias após a pulverização, ficando abaixo do nível de dano econômico (4 ninfas/metro linear), em decorrência da baixa precipitação ocorrida no período. O isolado UFGD 22 apresentou menor população de ninfas (1,5) e de adultos (0,8) por metro linear, com eficiência de controle de 85,9 e 75,0% para ninfas e adultos, respectivamente. O isolado IBCB 425 foi mais eficaz causando, em média, 97,9% de parasitismo para ninfas e 91,3% de parasitismo para os adultos, demonstrando o poder residual, decorridos 120 dias da aplicação.Research, Society and Development2020-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/514410.33448/rsd-v9i8.5144Research, Society and Development; Vol. 9 No. 8; e268985144Research, Society and Development; Vol. 9 Núm. 8; e268985144Research, Society and Development; v. 9 n. 8; e2689851442525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/5144/4798Copyright (c) 2020 Maria Eliete Barbosa de Almeida, Elisângela de Souza Loureiro, Alessandra Fequetia Freitas, Anderson Souza de Almeida, Luis Gustavo Amorim Pessoahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAlmeida, Maria Eliete Barbosa deLoureiro, Elisângela de SouzaFreitas, Alessandra FequetiaAlmeida, Anderson Souza dePessoa, Luis Gustavo Amorim2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5144Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:45.193719Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
