Abstract:	This study was focused on the response to heat shock of some Drosophila melanogaster natural populations collected from different Romanian ecosystems affected by the presence of stressors like: high salinity contained in soils, natural radioactivity, intensive mining activity or drought and aridity. A short heat shock applied to Drosophila melanogaster natural populations does not affect lifespan, but the mortality increased in case of Drosophila melanogaster Socodor and Bucovăţ populations. We did not detect any overexpression for some genes involved in thermal stress as follows: Hsp 70, Map 205, Cdc2 and Dp 53, respectively Adh as reference gene.
