| Abstract | The silvering thrips Enneothrips flavens Moulton, is considered a major pest of peanuts in Brazil, for its widespread occurrence, the population levels achieved and damage the crop. This study aimed to evaluate the effect of silicon and acibenzolar-Smethyl (ASM) on the population of E. flavens and its yield reflections of groundnut. For both experiments were sampled 10 leaves per plant of the cultivar IAC RUNNER 886, the creeping growth habit. For the experiment with silicon evaluated the following treatments: a spraying leaf of silicon at dose of 150 g ha -1 at 20 days after plant emergence, two spraying leaf of silicon at a dose 150 g ha -1 to 20 and 55 days and control. ASM for the treatments were the basis for one spraying leaf of ASM at 20 g ai ha -1 at 20 days after plant emergence, two spraying leaf of ASM at dose 20 g a.i ha -1 at 20 and 55 days and control. The experiments were conducted in a completely randomized design in a soil classified as Oxisol. The results showed that spraying silicon provided plants protection peanut reducing the number of adults and nymphs of thrips E. flavens and avoided losses in yield of about 31.30% of in pods peanuts and 28.85% in grains. For the purposes of acibenzolar-S-methyl showed an increase in the plants protection peanut by reducing the population of adults and nymphs of E. flavens |
