Diversity and abundance of mites in citrus from Múgica and Gabriel Zamora, Michoacán. Rev. Mex. Cienc. Agríc [online]. 2024, vol.15, n.5, e3724.  Epub Dec 03, 2024.

Considering the importance of both phytophagous and beneficial mites and the need to deepen the study of the species present in economically important crops such as citrus, this research aimed to know the diversity of mite species present in citrus (Citrus spp.) crops and to compare their abundance in open-field crops, nursery, and backyard in the municipalities of Gabriel Zamora and Múgica, Michoacán. Collections were carried out by the direct collection method from January to June 2022; a total of 25 collections were made in five localities and eight hosts; the mites present were counted and placed in semi-permanent preparations and were identified with different taxonomic keys. A total of 273 mites of nine species were collected and identified; P. oleivora, B. yothersi, E. banksi, Eutetranychus sp., P. citri, and Tetranychus sp. were identified in phytophages, and E. ho, E. concordis, and a morphospecies of the family Iolinidae in predators. Both municipalities had a similar number of specimens collected; however, Gabriel Zamora showed greater diversity, with eight species. E. banksi was the most abundant in Gabriel Zamora (63.97%) and P. oleivora was the most abundant in Múgica (67.89%). Regarding the type of production system, the open-field crop was the one that presented the greatest diversity and abundance, with six species and 48% of the specimens collected.
