Abstract

It is known that four Trioza species attack avocado foliage, with Trioza anceps Tuthill (commonly called the avocado psyllid) being a widespread pest in Mexico and Central America. Both nymphs and adults feed on young leaf sap, but the nymphs induce avocado leaf galls by injecting a toxin during feeding, triggering tissue hyperplasia and hypertrophy. This leads to severe leaf deformations, stunted tree growth, and overall decline in plant health [1]. The aim of the present research was to evaluate the efficacy of nanomaterials synthesized via the sol-gel method for the control of T. anceps. The treatments included silicon oxide, silicon oxide with pine bark extract, silicon oxide with pine resin, and silicon oxide with both pine bark extract and pine resin. The nanomaterials were characterized prior to laboratory testing. Among them, the SiO₂-pine resin formulation proved to be the most effective, achieving 100% mortality of T. anceps nymphs by day 7 and belonging to the highest statistical efficacy group (group a) according to Tukey’s HSD test (p < 0.05). in [2]. Material characterization confirmed physicochemical properties enhancing phytoprotective effects, positioning silica-based nanomaterials as sustainable alternatives in modern agriculture [3, 4].

二氧化硅基纳米材料用于控制三叶线虫病：实验室生物测定和初步现场观察

众所周知，有四种Trioza会攻击鳄梨的叶子，其中Trioza anceps Tuthill（通常称为鳄梨木虱）是墨西哥和中美洲广泛存在的害虫。若虫和成虫都以嫩叶汁液为食，但若虫在进食过程中通过注射毒素诱发牛油果叶瘿，引发组织增生和肥大。这导致严重的叶片变形，树木生长受阻，以及植物健康指数的整体下降。本研究旨在评价溶胶-凝胶法制备的纳米材料对柞蚕的防治效果。氧化硅处理、氧化硅加松皮提取物处理、氧化硅加松脂处理、氧化硅加松皮提取物和松脂处理。在实验室测试之前对纳米材料进行了表征。其中，二氧化硅-松脂配方效果最好，第7天时达到100%的死亡率，根据Tukey的HSD检验，属于最高的统计疗效组（a组）（p < 0.05）。在[2]。材料表征证实了其物理化学特性增强了植物保护作用，将硅基纳米材料定位为现代农业的可持续替代品[3,4]。此图像的替代文本可能是使用AI生成的。

期刊介绍： The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
