Abstract

Abstract The electrophoretic protein pattern of the male accessory gland in Drosophila sechellia differs from those in the sibling species D. melanogaster, D. simulans and D. mauritiana. The male-specific sex peptides isolated from D. melanogaster and D. sechellia are qually efficient in repressing female sexual receptivity in these four sibling species, but have no effect on females of a distantly related species D. funebris. Sequencing of the sechellia-peptide shows that it consists of 36 amino acids and differs from the melanogaster-peptide reported previously only in three amino acids at positions 8, 11 and 12.
