title: [Organogenesis of sterile ovaries and testes after cauterization of pole cells of colorado beetle embryos (Leptinotarsa decemlineata SAY)].
abstract: Cauterization of pole cells in embryos of the Colorado beetle does not prevent organogenesis of the gonads. So, pole cells do not govern to the differentiation of the gonadal mesoderm (this latter is limited to abdominal segments 6, 7 and 8). Moreover, this mesoderm develops into testis or ovary even without any innitial germ cells.
