A separate investigation constituted the study of rare and disappearing species of coleopterans from the investigated territory [3, 4, 7, 20].

Also in recent years a series of papers have been published regarding the coleopterans from natural areas protected by state. Here can be mentioned the papers of: Andreev et al. [1]; Neculiseanu Z., E. Baban [19] E. Baban [2, 3], Abstract of biological diversity [10]. In these papers are presented faunistic, ecological, zoogeographical data of some scarabeoid coleopteran species in this area. Up to present there was no work of synthesis of performed researches on scarabeoid coleopteran from forest ecosystems identified in the scientific reserve “Codrii”.

Materials and methods

As base for this paper served the collections and studies performed during 2004—2014 in the forest ecosystems of the scientific reserve “Codrii”. Also, the materials from the entomological collection of the Institute of Zoology of the ASM were used. Faunal material was collected in seven forest types that represent different characters in terms of vegetation: oak forest mixed with beech; forest of oak mixed with hornbeam; mixed forest of oak and lime-ash; forest oak with hornbeam and ash mixture; mixed forest of hornbeam and oak; oak forest with a mixture of ash and lime; ash forest mixed with hornbeam.

Scarabeoid coleopterans were collected in forest ecosystems by use of soil traps of Barber type, using vessels with a volume of 700 ml. As the preservative-fixer liquid served the concentrated solution of sodium chloride (NaCl) and acetic acid (CH3COOH), as well as collection using entomological net, manual collection from various plants, shrubs, ground surface etc. In total during 10 years they were collected and analyzed about 9,000 individuals.

Identification of collected scarabeoids was done based on the work of the authors Panin [21] Medvedev [18] Gidei, Popescu [13].

Results and discussions

After the analysis of data obtained by the authors and those from the literature, it was emphasized the presence in the scientific reserve “Codrii” of a rich fauna of scabaeoid coleopterans, which includes a large number of taxa. To prepare the list of scarabeoid fauna there were used works: Chimisliu [8], Cilipic [9], Bacal et al. [5]. It was established that scarabeoid beetle fauna of the forest ecosystems is represented by 3 families, 29 genera and 79 species (tab. 1), of which 4 species are rare and endangered in Moldova and are included in the III edition of the Red Book of the Republic Moldova: Protaetia aeruginosa Dr., 1770; Oryctes nasicornis (L., 1761), Gnorimus octopunctatus L., 1758; Lucanus cervus (L., 1758) [7].
