Abstract

The structure of the female reproductive tract, and the patterns of oogenesis, fertilization and embryogenesis were examined from two adult female Loa loa (Nematoda: Filarioidea) from Gabon. They were found to be indistinguishable in the two specimens, and almost indistinguishable from the pattern previously described from Dirofilaria immitis, except in chromosome number. Loa loa has 2n=10+X0.
