[Development of the corpora allata, oocytes and collateral glands during the 1st gonotrophic cycle of Blattella germanica (L.)].

In the present paper volumetric changes of corpora allata (CA) during the first gonotrophic cycle of Blattella germanica (L.) are studied in connection with the growth of oocytes and the collateral glands. Volumetric changes of CA are rather irregular and not well correlated with the uniform development of oocytes or collateral glands. The asymmetry of the paired CA is also discussed.
