Elena BABAN, Nina TÄLÄMBUTÄ Analysis of the geographical spread of scarabeoids from the forest ecosystems of the scientific reserve “Codri” was based on assumptions of renowned entomologists, which allowed us to observe that coleopteran fauna in this area is composed of elements of very different faunal origins and period, and on fauna formation in investigated area definitive influence had the glacial refuges, the centers of arboreal and eremial spreading [6, 11]. The zoogeographical analysis was found that scarabeoid coleopterans fauna identified in the scientific reserve “Codrii” belongs to 8 zoogeographical elements: Trans-Palearctic, European, Euro-Siberian, cosmopolite, Holarctic, Euro-Caucasian, Euro-Mediterranean and Mediterranean, with the predominance of species with European area type (20%), Trans- Palearctic (19%) and Mediterranean - 17% (fig. 3). Scarabeoid coleopterans fauna from the forest ecosystems of the scientific reserve “Codrii” qualitatively resembles to that of Central Europe. This is of great interest due to the position of given territory at the interference of biogeographic zones Central-European, Eurasian and Mediterranean. The works published in the course of about a hundred years and personal investigations reveal the importance of these coleopterans in maintenance of forest ecosystems stability. Conclusions Scarabeoid fauna from the forest ecosystems is represented by 3 families, 29 genera and 79 species. In investigated ecosystems there were recorded 4 rare and endangered species: Protaetia aeruginosa Dr., 1770; Oryctes nasicornis (L., 1761), Gnorimus octopunctatus L., 1758; Lucanus cervus (L., 1758), included in the 3rd edition of the Red Book of Republic of Moldova. After trophic regime the fauna of scarabeoid coleopterans from the forest ecosystems of scientific reserve “Codrii” was composed of three trophic groups: 55% are coprophagous species, followed by phytophagous 41% and only 3% were xilophagous. The zoogeographical analysis was found that scarabeoid coleopterans fauna belongs to 8 zoogeographical elements: Trans-Palearctic, European, Euro-Siberian, cosmopolite, Holarctic, Euro-Caucasian, Euro-Mediterranean and Mediterranean, with the predominance of species with European area type (20%), Trans- Palearctic (19%) and Mediterranean - 17%. 92 Fig. 3.
