Silicon (Si) is considered an important component for plant growth, development, and yield in many crop species. Silicon is also known to reduce plant pests. Although Si, the major component of soil next to oxygen, it is not used as a major nutrient by crop plants. However, extensive literature demonstrate the beneficial effects of soluble silicates, like silicon [orthosilicic acid (Si(HSiO)], on reducing biotic stress in crop ecosystems. In general, monocots tend to accumulate substantially more Si in plant tissues than dicots. Si accumulates in plant cell walls, providing protection by increasing the synthesis of lignin and phenolic compounds and activating the endogenous chemical defenses of plants including volatile and non-volatile compounds and other physical structures like trichomes. This review provides an overview of the history of silicon use in agriculture in India, for the management of insect pests. The future research needs in this field of study are also presented.
硅（Si）被认为是许多作物生长、发育和产量的重要组成部分。硅还已知可以减少植物害虫。尽管硅是土壤中仅次于氧的主要成分，但它不是作物植物的主要营养物质。然而，大量文献表明可溶性硅酸盐（如硅[正硅酸（Si(HSiO)）]）对减少作物生态系统中的生物胁迫具有有益作用。一般来说，单子叶植物在植物组织中积累的硅比双子叶植物多得多。硅积累在植物细胞壁中，通过增加木质素和酚类化合物的合成以及激活植物的内源性化学防御来提供保护，包括挥发性和非挥发性化合物以及其他物理结构如毛状体。 本文综述了印度农业中硅的使用历史，用于管理虫害。还提出了该研究领域未来的研究需求。
