CABRERA-MIRELES, Héctor; MURILLO-CUEVAS, Félix D.; VILLANUEVA-JIMENEZ, Juan. A.  e  ADAME-GARCIA, Jacel. Oribatids, collembola and ants as indicators of soil disturbance in agricultural production systems. Ecosistemas y recur. agropecuarios [online]. 2019, vol.6, n.17, pp.231-241.

The abundance, richness and diversity of oribatids, collembola and ants were compared as indicators of soil disturbance found under (traditional) minimal management systems, transition management and technified handling of the mango crop, as well as in the technified management system of sugarcane in the Central Veracruz region in Mexico. In each management system, soil and litter samples were taken, in which arthropods were collected using the Berlese-Tullgren funnels method. The samplings were carried out in three seasons of the spring, summer and winter for 2017 and 2018. The most abundant species were the mites Ceratozetes sp., Archegozetes longisetosus, Scheloribates laticlava, Paropanolophus sp. and Pseudoparasitus sp., Collembola Pseudosinella sp. and Seira sp., and the ants Solenopsis conjurata, Solenopsis terricola, Pyramica brevicornis and Pachycondyla harpax. Colémbolos and ants were more abundant under the mínimum management system followed by management in transition, and finally in the systems of technified management of mango and sugarcane. On the other hand, the oribatids were more abundant in the management system of mango cultivation. The management system technified with sugar cane had an average of 12.3 individuals, 1.3 species and amount of 0.26 diversity, which was significantly lower than the other systems (abundance, F3,112 = 7.2, p = 0.0001, richness, F3,112 = 13.3, p = 0.0001, diversity, F3,112 = 13.2, p = 0.0001), which did not show significant differences among themselves (p > 0.05).
