Abstract：
UNASSIGNED: This study focused on evaluating the diversity and richness of the edaphic macrofauna in eight banana farms in the western zone of Nicaragua.
UNASSIGNED: The sampling design was random and descriptive, it was divided into two phases, the first was the collection of the sample, and the second was the classification, coding, and storage of the extracted macrofauna populations. The sampling method employed included the extraction of soil and litter samples. Soil samples were collected using a wooden frame (monolith), with each sample weighing approximately 1 kilogram and taken from a depth of 0.20 cm. Litter samples were collected from the soil surface. A total of 80 samples were collected, with 40 soil samples and 50 litter samples obtained across the 8 plantain farms.
UNASSIGNED: The results showed that the relative abundance of biodiversity was higher in the 0-20 cm soil depth stratum than in the branch and leaf biomass strata. The values of the diversity indices of Simpson\'s Dominance, Shanon, Margalef, and Equity were in the normal range, with a tendency towards low diversity. Likewise, in the richness of species, the Dominance or most abundant genus were earthworms (Oligochaeta) and Hymenoptera ( Solenopsis, Leptothorax, Camponotus, Pheidole), indicating the directly proportional relationship, that is to say, that the greater the number of earthworms the production increases and the greater the number of Hymenoptera it decreases, confirmed with the Pearson correlation coefficient with a reliability of 95%.
UNASSIGNED: It was concluded that based on the estimates of the diversity indicators, two detritivore genus (earthworms and Hymenoptera) were the ones with the more dominance, being important in the production of the banana agrosystem due to the decomposition of organic matter and its nutritional contribution to the plant. We observed a direct correlation with earthworms and an indirect relationship with Hymenoptera.

摘要：
■这项研究的重点是评估尼加拉瓜西部地区八个香蕉农场的大型动物的多样性和丰富性。
■抽样设计是随机和描述性的，它分为两个阶段，首先是样本的收集，第二个是分类，编码,以及提取的大型动物种群的储存。随后，多样性和物种丰富度指数，相对丰度,按官能团进行了估计。
■结果表明，在0-20cm土壤深度地层中，生物多样性的相对丰度高于在树枝和叶片生物量地层中。Dominion多样性指数的值，辛普森,Shanon,玛格丽特,公平在正常范围内，具有低多样性的趋势。同样，在物种的丰富程度上，主要或最丰富的属是earth（Oligochaeta）和膜翅目（Solenopsis，钩胸,Camponotus,Pheidole),表示成正比关系，也就是说,增加的蚯蚓数量越多，减少的膜翅目数量就越多，用皮尔逊相关系数证实，可靠性为95%。
■得出的结论是，根据对多样性指标的估计，两个有害鱼属(蚯蚓和膜翅目)是存在最多的，由于有机物的分解及其对植物的营养贡献，在香蕉农业系统的生产中很重要。我们观察到与蚯蚓直接相关，与膜翅目间接相关。
