Histochemical studies on the effect of propoxur on yolk synthesis in the ovarioles of the blow fly, chrysomyia albiceps [Wiedemann] [diptera: calliphoridae]

The effect of the carbamate insecticide, propoxur, on yolk synthesis in the ovarioles of the blow fly, Chrysomyia albiceps [Wiedemann] was studied. Histochemical studies showed that DNA, RNA, protein and lipid synthesis in propoxur-treated ovarioles decreased as compared with that in non-treated ovarioles, with some deteriorations in the chromatin in the nuclei of some nurse cells. On the other hand, the synthesis of carbohydrate is more or less not affected
