Agroforestry systems in the tropics exhibit high heterogeneity in plant species composition and structural configuration. However, few studies evaluated the seasonal shift in arthropod alpha diversity and abundance in agroforestry systems in the tropics. This study was designed to analyze the composition, abundance, and alpha diversity of arthropod orders in five agroforestry systems in the humid tropic of Tabasco, Mexico. The agroforestry systems compared were shade trees in plantations (ShTP), living fences (LF), alley farming (AF), slash-and-burn agriculture (SBA), and grazing plantations (GP) during dry and rainy seasons. Arthropods were collected using pitfall traps, classified at the order level, and counted to estimate the abundance. A total of 10,271 arthropod individuals were collected that belong to seven orders. Hymenoptera was the most abundant group, accounting for 64.7% of the total count, followed by Coleoptera, Collembola, Araneae, Hemiptera, Diptera, and Orthoptera. Arthropod alpha diversity and abundance varied significantly among the agroforestry systems and between the rainy and dry seasons. The agroforestry systems AF, GP, and ShTP showed a higher diversity (Shannon index) and dominant orders (Simpson index) in the rainy season compared to the dry season. The seasonal shift of the different arthropod orders varied among agroforestry systems, while the Orthoptera did seasonally vary across the agroforestry systems. This study suggests the interactive effects of seasons and agroforestry systems on arthropod abundance and diversity.

热带农林业系统在植物物种组成和结构配置方面表现出高度异质性。然而，很少有研究评估热带农林复合系统中节肢动物α多样性和丰度的季节性变化。本研究旨在分析墨西哥塔巴斯科州湿热带地区五个农林复合系统中节肢动物目的组成、丰度和α多样性。比较的农林业系统包括种植园遮荫树（ShTP）、活栅栏（LF）、巷道农业（AF）、刀耕火种农业（SBA）以及旱季和雨季的放牧种植园（GP）。使用陷阱收集节肢动物，按目级别分类，并计数以估计丰度。总共收集了 10,271 只节肢动物个体，属于 7 个目。膜翅目数量最多，占总数的64.7%，其次是鞘翅目、弹尾目、蜘蛛目、半翅目、双翅目和直翅目。节肢动物α多样性和丰度在农林复合系统之间以及雨季和旱季之间存在显着差异。与旱季相比，农林复合系统 AF、GP 和 ShTP 在雨季表现出更高的多样性（香农指数）和优势目（辛普森指数）。不同农林复合系统中不同节肢动物目的季节性变化各不相同，而直翅目在不同农林复合系统中确实存在季节性变化。这项研究表明季节和农林业系统对节肢动物丰度和多样性的交互影响。双翅目、直翅目。节肢动物α多样性和丰度在农林复合系统之间以及雨季和旱季之间存在显着差异。与旱季相比，农林复合系统 AF、GP 和 ShTP 在雨季表现出更高的多样性（香农指数）和优势目（辛普森指数）。不同农林复合系统中不同节肢动物目的季节性变化各不相同，而直翅目在不同农林复合系统中确实存在季节性变化。这项研究表明季节和农林业系统对节肢动物丰度和多样性的交互影响。双翅目、直翅目。节肢动物α多样性和丰度在农林复合系统之间以及雨季和旱季之间存在显着差异。与旱季相比，农林复合系统 AF、GP 和 ShTP 在雨季表现出更高的多样性（香农指数）和优势目（辛普森指数）。不同农林复合系统中不同节肢动物目的季节性变化各不相同，而直翅目在不同农林复合系统中确实存在季节性变化。这项研究表明季节和农林业系统对节肢动物丰度和多样性的交互影响。与旱季相比，ShTP在雨季表现出更高的多样性（香农指数）和优势目（辛普森指数）。不同农林复合系统中不同节肢动物目的季节性变化各不相同，而直翅目在不同农林复合系统中确实存在季节性变化。这项研究表明季节和农林业系统对节肢动物丰度和多样性的交互影响。与旱季相比，ShTP在雨季表现出更高的多样性（香农指数）和优势目（辛普森指数）。不同农林复合系统中不同节肢动物目的季节性变化各不相同，而直翅目在不同农林复合系统中确实存在季节性变化。这项研究表明季节和农林业系统对节肢动物丰度和多样性的交互影响。
