    Arthropod biodiversity is fundamental to the ecological balance in agricultural systems; however, agricultural intensification can negatively affect the diversity and abundance of these organisms. The study aimed to compare the diversity and abundance of arthropods in three crops, guaba, Claudia, and peach, and to evaluate the influence of climatic and temporal factors on these parameters. Sampling was carried out for 18 weeks in the three crops using 15 pitfall traps to evaluate these parameters. In guaba, arthropod abundance ranged from 29 to 242 individuals, with peaks in weeks 7, 9, 13, and 14. Thrips were the most abundant (1167 individuals), followed by mealybugs (879) and spiders (292). In Claudia, with higher relative diversity, 40 and 218 individuals were captured, with peaks in weeks 3, 9, 14, and 18; thrips (585) and mealybugs (590) dominated, but diversity was balanced. Peach catch ranges were from 34 to 265 individuals, with peaks in weeks 10, 14, 16, and 18. Mealybugs (1167) and ants (585) were predominant. The Insecta class was the most abundant of all crops, with peaches showing the highest number of individuals. Arachnida showed similar abundances between crops, while Chilopoda was more abundant in claudia. Statistical analyses found no significant relationship between arthropod abundance/diversity and climatic variables or weekly variations, although there were differences between sampling points. Although significant differences in diversity were observed between the three crops, no differences in arthropod abundance were found that could be explained by climatic conditions or temporal variations. It suggests that other factors not evaluated, such as edaphic characteristics or agricultural management, could influence arthropod diversity and abundance.
