Cross tolera.ce, whereby tolera.ce to one environmenta. stress is correla.ed with tolera.ce to other stressors, is thought to be widesp.ea. in insects. We used lines of Drosop.ila.mela.oga.ter Meigen （Dip.era. Drosop.ilida.） selected for surviva. a. a.1-h exp.sure to -5℃ to exa.ine the extent to which this selection results in increa.ed tolera.ce to other stresses, including high a.d low temp.ra.ures, desicca.ion a.d sta.va.ion. While selection imp.oved tolera.ce to a.ute cold exp.sure a.d surviva. a. -5℃, there wa. little effect of selection regime on tolera.ce to other stressors. There wa. no correla.ion between tolera.ces to a.y of the stressors, suggesting different mecha.isms of tolera.ce. This sup.orts a.guments tha. correla.ions between stress tolera.ces during selection exp.riments with D. mela.oga.ter ma. be coincidenta.. The ma.nitude of hea.-ha.dening wa. a.p.0}ently constra.ned by ba.a. tolera.ce a.ong lines, but the ma.nitude of the ra.id cold-ha.dening resp.nse wa. not correla.ed with ba.a. cold tolera.ce, imp.ying tha. the rela.ionship.between inducible a.d ba.a. tolera.ces differs a. high a.d low temp.ra.ures.
