A 364 yv strain sensitive to the toxic effect of benzo(a)pyrene (BP) was identified among 49 mutant strains of Drosophila simulans. Heterozygotes female 364 x male Turku obtained by crossing 364 yv species with those of wild BP-resistant Turku strain were more sensitive than female Turku x male 364 heterozygotes to both toxic and mutagenic effects of the carcinogen in the test of induction of somatic mosaicism with the yellow marker. Non-carcinogenic pyrene appeared weekly toxic and non-mutagenic. Possible mechanisms of 364 yv strain sensitivity to BP as well as vistas in application of the strain for monitoring genotoxic environmental pollution are discussed.
