LARA DIAZ, Ana Verónica et al. Spatial modeling of Oligonychus perseae (Tuttle, Baker and Abbatiello) using geostatistical techniques. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.6, pp.1405-1416.  Epub 02-Out-2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i6.1951.

Within the pests that affect the avocado crop we find Oligonychus perseae or better known as crystalline spider. This mite produces affectations in the epidermis of the leaves discoloring the injured areas, in severe attacks they cause defoliation and low production, all this as a result of the extraction of the cellular content of the tissues. In the State of Mexico, there are about 10 000 hectares planted with avocado, with an average production of 15. 602 t ha-1. The spatial distribution of O. perseae in four municipalities producing avocado var. Hass through the application of geostatistical analysis and ordinary krigeado. The results show that the crystalline spider populations are presented in an aggregate way, adjusting mostly spherical models. The area infested with the mite exceeded 73% of the municipality in all samples and the maximum number of individuals found was 1 445 organisms per tree. The most affected municipalities were Coatepec Harinas and Donato Guerra.
