Thirty accessions of cotton (Gossypium) in the INIFAP genebank in the Iguala Experimental Field were analyzed for resistance to eriophyid mites. Vegetative structures such as leaves and petioles and reproductive structures such as the bract calyx with galls were collected from cotton plants. Galls were cut into cross section to locate mites; taxonomic keys were used to identify the mites. Damage to accessions of cotton was evaluated on a scale of six classes. Damage by eriophyid mites was analyzed with PROC RANK, subjecting it to analysis of variance with PROC GLM, and mean comparison by Tukey (P = 0.05) using statistical software SAS^® 9.2. Eriophyidae was reported associated with formation of galls in cotton. Severity of damage was 0 to 85%, but cotton accessions TOA-06, FZ-06, GOS-16, GOS-34, TOA-09, TOA-02, GOS-17, TOA-04, and TOA-05 were resistant. More studies of biology and ecology and molecular analysis are needed to better understand and develop management strategies against mites in cotton.
