dc.description.abstractThe effects of chemical inducers of plant resistance on folivorous beetles and predatory insects in Solarium tuberosum L. were evaluated. The effects of these chemical inducers on crop development and yield were also determined. The experiment was conducted with cv. Emeraude using a randomised complete-block design with four treatments and six replications: 1 - control; 2 - 1% silicic acid; 3 - 0.02% acibenzolar-S-methyl (ASM); and 4 - 1.15% diatomaceous earth (DE). Treatments 2, 3 and 4 were applied by spraying plant foliage every 10 days, total of five applications. The injuries and damages caused by beetles were evaluated. There were no significant differences in the presence of folivorous and predatory beetles in the aerial plant mass and the surrounding soil. However, the plants treated with silica or DE were less preferred by defoliators. Spraying with silicic acid, ASM and DE produced significant increases in plant diameter and height without affecting productivity. The application of silicic acid, ASM or DE increased protection against herbivorous insects and decreased tuber damage.pt_BR
dc.description.resumoSe evaluaron los efectos de los inductores químicos de resistencia de plantas a insectos en los escarabajos hebívoros y otros insectos depredadores en Solanum tuberosum. Los efectos de estos inductores químicos también se evaluaron en el desarrollo y en el rendimientos del cultivo. El experimento se llevó a cabo con el cv. Emeraude, utilizando un diseño de bloques al azar con cuatro tratamientos y seis repeticiones: 1 - Control, 2 - 1% de ácido silícico, 3 -0,02% acibenzolar-s-metil (ASM), y 4 - 1,15% tierra de diatomeas (DE). Los tratamientos 2, 3 y 4 se aplicaron por aspersión en el follaje de las plantas cada 10 días, un total de cinco aplicaciones. Se evaluaron las lesiones y los daños causados por Diabrotica speciosa. No hubo diferencias significativas en la presencia de D. speciosa y depredadores en la parte aérea de la planta y en el suelo circundante. Sin embargo, las plantas tratadas con ácido silícico o DE fueron menos preferidas por D. speciosa y el efecto asociado con ácido silícico, ASM y DE produjo un aumento significativo en el diámetro y la altura de la planta sin afectar la productividad. La aplicación de ácido silícico, ASM o DE aumentó la protección contra insectos y disminuyó los daños al tubérculo.pt_BR
