Nine accessions of wild Manihot species, M. esculenta ssp. flabellifolia , M. esculenta ssp. peruviana , and M. carthaginensis ssp. glaziovii , and two clones of M. esculenta (Cigana Preta and Sacaí) were evaluated under la boratory conditions at 25 ± 1°C, 70 ± 10% RH, and a 12-h photophase. Daily observations during the mite life cycle stages (larva-adult) were recorded. The data were subjec ted to an analysis of variance, a Scott-Knott test (5%), and Singh criterion, cluster, and principal co mponent analyses. The larval-adult pe riod ranged from 5.53 to 7.01 days: the longest period was observed on an M. glaziovii accession (GLA-19-DF) and the shortest on an M. flabellifolia accession (FLA-025V). The UPGMA method allowed the division of the genotypes into six groups, with the greatest distance between the FLA-025V and GLA-19-DF accessions. The first two main components explained 77.50% of the total accumulated variation. The association of the longest cycle duration of M. tanajoa with the lowest larval-adult viability suggests that GLA-19-DF is less favora ble to mite development compared to the other accessions. Significant variability among the genotypes was observed. 2015 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303042425006 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
