[Evolution of the adipose tissue during the postembryonic development in Coleoptera Catopidae. I. Studies in Choleva fagniezi and Speophyes lucidulus (author's transl)].

Cytological studies of the fat body have been performed during the postembryonic development of 2 Coleoptera Catopidae: Choleva fagniezi and Speophyes lucidulus. As in other insects, the cells store large amounts of glycogen, lipids and proteins during the larval life; these reserves would be lysed and used during the metamorphosis. According to the species, protein globules are constituted at different larval life periods. In Choleva fagniezi they appear during the 3rd and last larval instar. In Speophyes lucidulus, protein globules appear during the 10 first days of the 1st larval instar. In the prenymphs of the 2 species, the protein globules become rich in RNA.
