Abstract：
:Coccoids (Coccinea, Coccoidea, Coccomorpha, scale insects, scales) are a highly diverse group of ectoparasitic insects. They comprise 2 subgroups: primitive archaeococcoids (= Orthezioidea sensu Koteja) and advanced neococcoids (= Coccoidea sensu Koteja). The ovaries of coccoids consist of numerous short telotrophic-meroistic ovarioles. The ovarioles of all investigated species share common characters (e.g. the same mechanism of ovariole development, lack of terminal filaments, occurrence of single oocytes in the vitellaria) supporting the concept of monophyletic origin of this group. Despite these characteristics, the ovaries of archaeococcoids and neococcoids differ in the number of germ cells (oocytes + trophocytes) constituting a single ovariole. In primitive families (Ortheziidae, Margarodidae), this number is relatively large (15-58), whereas in advanced ones (Pseudococcidae, Kermesidae, Eriococcidae, Cryptococcidae, Coccidae, Diaspididae) it is small and usually does not exceed 8. The comparative analysis of the ovary structure in the representatives of Coccinea and closely related Aphidinea (aphids) has revealed that: (1) the organization of archaeococcoid ovaries is more similar to those of aphids than to neococcoids and (2) during the evolution of Coccinea a gradual reduction in the number of germ cells in ovarioles took place.
