Summary

The present work has been directed on fauna studying of Bruchidae, Nemonychidae, Anthribidae, Rhynchitidae and Attelabidae beetles families from Republic of Moldova, revelation of ecological peculiarities and their values as components of biodiversity.

Investigations presented in the PhD thesis, have carried out in the Centre for General and Molecular biology and in the laboratory of Entomology, Institute of Zoology, Moldova Academy of Sciences during 2004-2008.

The main materials were collected from the different regions of Republic of Moldova and also entomological museum collections of Institute of Zoology, Moldova Academy of Sciences, Institute of plant protection and farming agriculture, Moldova Academy of Sciences have been used. Altogether, 59 species from 32 genera of Bruchidae, Nemonychidae, Anthribidae, Rhynchitidae и Attelabidae families were collected from the 156 collection sites of the Republic of Moldova. Among them 9 species and 1 genus (Callosobruchus) from Bruchidae are specified for the first time for regional fauna.

On the basis of molecular-genetic analysis with 28S rDNA marker for 4 species Rhynchitidae have established that species Tatianaerhynchites aequatus (L.), Neocoenorhinidius pauxillus (Germ.) and Rhynchites bacchus (L.), Epirhynchites auratus (Scop.) are close related and should be carried to genus Neocoenorhinidius and Rhynchites, respectively.

According to trophical preferences investigated beetles are led with 13 families of host plants. The main species number were detected in families Fabaceae (22 species), Rosaceae (15), Fagaceae (12), Betulaceae (6), Resedaceae (6), Salicaceae (5), Corylaceae (4), Tiliaceae (3), Cristaceae (2), Ranunculaceae (2), Vitaceae (1) and Aceraceae (1). The trophical relationships between Bruchidae beetles and Fabaceae host plants have been established. The greatest numbers of species were detected on gg. Vicia (10), Lathyrus (8) and Pisum (5); 3 species – on Lens and Cicer; 2 species – on Phaseolus, Oxytropis, Onobrychis, Medicago, Cytisus, Glycyrrhiza and Melilotus; 1 species - Astragalus, Genista, Spartium, Albizia, Amorpha, Glycine and Halimodendron.

The geographic diversity analyses of beetles revealed 12 zoogeographic groups in Republic of Moldova: Euro-Mediterranean (24%), Trans-Palearctic (19%), Western-Palearctic (12%), European (11%), Euro-Siberian (9%) and Euro-Asiatic (9%), Cosmopolites (4%), Mediterranean (4%) and Eastern-Mediterranean (4%), Panpalearctic (2%) and Holarctic (2%).
