Summary

Artificial populations of Megaselia scalaris were reared in population cages and in overcrowded glass cultures respectively. The three types of sex-determination according to the I- or II- or III- chromosome were set in competition with different frequencies starting the artificial populations. The genetic background was varied by using different strains. An equilibrium between the types of sex-determination was reached in all the populations. The II M-type proved a disadvantage in all examinations. In well ventilated cages the I M-type was strongly successful. In overcrowded glass cultures the III M-type proved an eminent advantage.
