Megjegyzések:	Drosophila melanogaster samples were collected from a large population in two habitats: farmyards and distilleries. Samples were taken from two willages in each habitat. Three isofemale lines were established from all four samples and full-sib crosses were set each isofemale line. Activities of four enzymes (ADH,alfaGPDH, IDH and 6 PGDH) were measured in the offspring of each cross on starch gel after electrophoresis. Broad sence heritabilities and additive genetic variances were estimated in all four samples. Most of the activity variation was observed within the isofemale lines.The isofemale lines tended to be more different in the distilleries than in the farmyards. There was no significant difference in the average activities between the two habitats for any of the enzymes investigated. The additive genetic variance of the enzyme activities did not exhibit a consistent habitat pattern. In the farmyard habitat, we detected a higher activity variation in Tiszafüred than in the other village. Strong correlation was observed among the activities of the enzymes intestigated. Correlation coefficients indicated higher level of correlation in the samples collected in Tiszafüred than in those originating from Tiszaszőlős. The heritability values were rather high and they had a considerable variation both between the habitats and across the enzymes.
