The stink bug Glyphepomis spinosa Campos & Grazia (Hemiptera: Pentatomidae) is a potential rice pest in Brazil. This study evaluates the interaction between silicon sources and 3 rice cultivars (BRS Esmeralda, Canela de Ferro, and IRGA 417) and examines how increasing silicon levels affect the stylet probing behavior of G. spinosa. The experiment was set up in a completely randomized design with a 3 × 3 factorial scheme (silicon sources: calcium silicate, potassium silicate, a control, and 3 rice cultivars). Fertilizing rice plants with Si altered the probing behavior of the stink bug G. spinosa. The cultivar interaction by Si source was significant in a few variables. This was evidenced by longer periods without ingestion, prolonged time to the first stylet probe (initial probing), and less time spent in cellular maceration. This result supports the use of electropenetrography as a tool to evaluate resistance inducers in plants.
刺胫臭椿象 Glyphepomis spinosa Campos & Grazia（半翅目：猎蝽科）是巴西一种有潜力的水稻害虫。本研究评估了硅源与 3 种水稻品种（BRS Esmeralda、Canela de Ferro 和 IRGA 417）之间的相互作用，并研究了增加硅水平如何影响刺胫臭椿象的取食行为。该实验采用完全随机设计，具有 3×3 因子方案（硅源：硅酸钙、硅酸钾、对照和 3 种水稻品种）。用 Si 施肥会改变刺胫臭椿象的取食行为。Si 源的品种间相互作用在几个变量中具有显著性。这一点可以通过更长的不取食期、首次取食时更长的时间（初始探测）和更少的细胞研磨时间来证明。这一结果支持了用电穿透图作为评估植物诱导抗性的工具。
