The aim of this study was to establish the composition and amount of the arthropod predators of the soil, also the influence of the phytosanitary applications and labors on it, in the fields of artichoke and avocado crops. The research was conducted in commercial crops in the city of Vegueta-Huaura, since June til November 2016. The procedure consisted to install 10 pitfall traps for each investigated field, and the data gathering was every seven days. The collected individuals were separated in morphotypes. We registered every one of them with codes and identified them at the Klaus Raven Entomology Museum. We obtained the data of the total and relative number of predators, especies composition; the seasonal fluctuation curve of the species, the connection between the management of the crops and the pesticides applications with this curve; and the species accumulation curve. In both, avocado and artichoke crops, the collected predators belonged to order of Araneae, Coleoptera and Dermaptera. In artichoke, the specie with big amounts was Blennidus peruvianus (Col.: Carabidae), con 551 individuals. In addition to that, we found Mermessus fradeorum (Araneae: Linyphiidae) with 124 individuals, Labidura riparia y Euborellia sp., with 24 and 14 individuals correspondingly. In avocado, the most abundant species were spiders such as Loxosceles laeta (Sicariidae), Lycosa thorelli (Lycosidae) y Dysdera crocata (Dysderidae), with 153, 144 y 106 individuals correspondingly. Another species were Blennidus peruvianus with 50 individuals, Euborellia sp. and Labidura riparia, with 17 and 14 individuals. The seasonal fluctuation of the collected predators didn’t show a significant difference in temperature. Although it did show a negative impact of the management of the crops and the application of pesticides, especially the people that dairy harvest the artichoke stepping the ground around the plants. Besides the indicators of diversity showed that the sampling was close to 100% efficiency.
