Resumo: | The rednecked peanutworm Stegasta bosqueella, is identified as the main peanut (Arachis hypogaea L.) pest, with damage to the leaflets, new shoots and needle buds. Currently, peanut pest control is carried out with chemical pesticides, but that can cause problems in human health, as well as the selection of insect resistant populations. Therefore, the use of other strategies is necessary, in this scenario virus-based bioinsecticides practice appears as a control strategy with low human toxicity, combined with a low capacity to select insect resistant populations. The objective of this work was to evaluate the action of the commercial product Lepigen® (AcMNPV) on second instar caterpillars of S. bosqueella. The experiment was carried out in a completely randomized design with 30 replications, in which the treatments consisted of (1) Control (distilled water) + adjuvant (0.05%) and (2) Application of the commercial product Lepigen® based on AcMNPV at a concentration of 108 polyhedral / mL + adjuvant (0.05%). Based on the results, it was observed that S. bosqueella second instar larvae submitted to commercial product Lepigen® treatment application, showed 100% mortality at the end of the seventh day of evaluation, whereas in the control treatment, mortality of only 5 individuals was observed during the same period evaluated. In addition, S. bosqueella second instar larvae needed to consume just over 0.17 cm2 to exhibit 100% mortality in our study. Therefore, the commercial product Lepigen® based on the baculovirus AcMNPV is pathogenic to S. bosqueella second instar caterpillars. |

Therefore, the commercial product Lepigen® based on the baculovirus AcMNPV is pathogenic to S. bosqueella second instar caterpillars.El cogollero Stegasta bosqueella, se señala como la principal plaga del cultivo de maní (Arachis hypogaea L.), con daños en los folletos, nuevos brotes y brotes de los punteros. En el escenario actual, el control de plagas se lleva a cabo con el uso de insecticidas químicos, una herramienta que puede causar problemas a la salud humana, así como la selección de poblaciones resistentes. Por lo tanto, el uso de otras estrategias es necesario, en este escenario el uso de Los bioinsecticidas basados en virus aparecen como una herramienta de control con baja toxicidad para la salud humana, combinada con una baja capacidad para seleccionar poblaciones resistentes. El objetivo de este trabajo fue evaluar la acción del producto comercial Lepigen® (AcMNPV) en orugas de segundo estadio de S. bosqueella. El experimento se realizó en un diseño completamente al azar con 30 repeticiones, en el que los tratamientos consistieron en (1) Control (agua destilada) + adyuvante (0.05%) y (2) Aplicación del producto comercial Lepigen® basado en AcMNPV a una concentración de 108 poliedros / ml + adyuvante (0.05%). Con base en los resultados, se observó que las orugas del segundo estadio de S. bosqueella sometidas a tratamiento con la aplicación del producto comercial Lepigen® presentaron una mortalidad del 100% al final del séptimo día de evaluación, mientras que en el tratamiento de control, mortalidad de solo 5 individuos evaluados durante el mismo período. Además, las orugas de segundo bosque de S. bosqueella necesitaban consumir poco más de 0.17 cm2 para mostrar un 100% de mortalidad en el ensayo. Por lo tanto, el uso del producto comercial Lepigen® basado en el baculovirus AcMNPV es patógeno para las orugas de segundo bosque de S. bosqueella.A lagarta-do-pescoço-vermelho Stegasta bosqueella, é apontada como principal praga da cultura do amendoim, (Arachis hypogaea L.), com danos em folíolos, brotações novas e gemas dos ponteiros. No cenário atual, o controle da praga é realizado com o uso de inseticidas químicos, ferramenta que pode acarretar problemas í saúde humana bem como a seleção de populações resistentes. Diante disso, a utilização de outras estratégias se faz necessário, neste cenário a utilização de bioinseticidas í base de vírus figura como uma ferramenta de controle com baixa toxicidade a saúde humana, aliado a uma baixa capacidade de selecionar populações resistentes. Objetivou-se com este trabalho avaliar a ação do produto comercial Lepigen® (AcMNPV) sobre lagartas de segundo ínstar de S. bosqueella. O experimento foi conduzido em delineamento inteiramente casualizado com 30 repetições, no qual os tratamentos constituíram-se de (1) Controle (água destilada) + adjuvante (0,05%) e (2) Aplicação do produto comercial Lepigen® a base de AcMNPV na concentração de 108 poliedros/ mL + adjuvante (0,05%). Com base nos resultados, observou-se que as lagartas de segundo ínstar de S. bosqueella submetidas ao tratamento com aplicação do produto comercial Lepigen® apresentaram 100% de mortalidade ao final do sétimo dia de avaliação, enquanto no tratamento controle foi observado mortalidade de apenas 5 indivíduos durante o mesmo período avaliado. Além disso, as lagartas de segundo instar de S. bosqueella precisaram consumir apenas pouco mais de 0,17 cm2 para apresentar 100% de mortalidade no ensaio. Portanto, o uso do produto comercial Lepigen® a base do baculovírus AcMNPV apresenta patogenicidade a lagartas de segundo ínstar de S. bosqueella.SAS2020-10-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.southamericansciences.com.br/index.php/sas/article/view/2410.17648/sas.v1i2.24South American Sciences; Vol. 1 Núm. 2 (2020): South American Sciences; e2024South American Sciences; v. 1 n. 2 (2020): South American Sciences; e20242675-722210.17648/sas.v1i2reponame:South American Sciencesinstname:Instituto Prosinstacron:PROSporhttps://www.southamericansciences.com.br/index.php/sas/article/view/24/31Copyright (c) 2020 South American Sciencesinfo:eu-repo/semantics/openAccessPinto, José Ricardo Lima do Nascimento, JoacirPolanczyk, Ricardo Antônio 2020-11-07T14:36:42Zoai:ojs2.southamericansciences.com.br:article/24Revistahttps://www.southamericansciences.com.br/index.php/sasPRIhttps://www.southamericansciences.com.br/index.php/sas/oaisoares-agro@hotmail.com || atenaconsultoriac@gmail.com2675-72222675-7222opendoar:2020-11-07T14:36:42South American Sciences - Instituto Prosfalse |
