Recent studies have been carried out to find out the dependence between bars and different properties of the host galaxy, and the influence of the local environment (groups, clusters, superclusters). We calculated the fraction of bars in two samples where the environmental effects are well controlled: a subsample of 180 isolated galaxies from the UNAM-KIAS catalogue obtained from SDSS DR5 and a subsample of 160 galaxies in pairs from the KPG catalogue obtained with the OAN-SPM 1.5 m telescope. We present preliminary results of bar fraction detected between these controlled environments and other environments such as groups and clusters that points towards bars are likely not triggered by galaxy interactions or maybe they are destroyed/weakened by them.
