摘要：

The ovarian type of 23 families of polyphage Coleoptera has been determined. The ovaries of all species belong to the telotrophic-meroistic type, indicated by nutritive cords connecting oocytes with the trophic tissue. These nutritive cords persist during previtellogenesis and the main part of vitellogenesis. The cytoplasm of the nutritive cords shows the same elements in similar frequencies as they were found in the nurse cell cytoplasm or in the ooplasm of oocytes during previtellogenesis. No indications are found supporting the idea that a reduction of nutritive cords early in ovarian development gives rise to a deviated panoistic ovary. The histological uniformity of nutritive cords among all investigated species as well as the fact that these species are scattered by chance among the polyphage Coleoptera seems to justify the conclusion that all Polyphaga s. str. have telotrophicmeroistic ovarioles. © 1979 Springer-Verlag.
