Abstract: | We describe six recessive autosomal male sterile mutations inDrosophila, generated by mobilization of single P-elements, exhibiting abnormal male courtship behavior. Detailed analysis of courtship
behavior elicited by virgin wild type females indicated that five of the six mutants are affected in the early steps of courtship.
The sixth mutant is blocked at the step of attempted copulation which occurs later in the courtship sequence. All of the mutants
have normal olfactory responses and normal locomotor activity. No defect in the visual modality has been observed for the
five mutants affected in the initiation of courtship. The mutant blocked at attempted copulation lacks the ‘on’ and ‘off’
transients, but this appears to be due to genetic background rather than the mutation itself. Abnormal spermatogenesis was
observed in five of the mutants. Spermatogenic defects vary and include lesions in the proliferation of the germline, in meiosis,
and in the differentiation and maturation of the spermatids into motile sperm. |
