Zoology
The diversity of leaf-beetles (Insecta, Coleoptera: Chrysomelidae) in the nature reserve “Pädurea Domneascd In “Pädurea Domneascä” Reserve there were identified Chrysomelidae species belonging to five zoogeographical groups. Among them the Euro-Siberian (7) and Transpalearctical (6) species are prevailing, followed by two European species, and by one Mediterranean and one Palearctic species (fig.l). The presence of species with a narrow spread area (European and Mediterranean) indicates the importance of the region chosen for the study in terms of biodiversity conservation. Fig. 1: Zoogeographical distribution of Chrysomelidae species from “Pädurea Domneascä” Reserve Some Chrysomelidae species are forestry pests. Their economic importance is often underestimated, since the caused injuries rarely lead to the total destruction of the plant. Feeding with green parts of the plant leads often to worsening the physiological state of the plant attacked. Commonly, Chrysomelidae feeding is more intensive in the larval stage, therefore the larvae harms more than the adult insect. A particular feature of Chrysomelidae is the relatively narrow trophic spectrum. Usually, each harmful species is trophically closely related to the injured species. However, leaf beetles, as well as the enthomofauna as a whole are an important component of biodiversity that should be taken into account, given their multi-faceted value that has not yet been sufficiently disclosed, although some species became rare or even disappeared. Conclusions As a result of investigations conducted during 2010-2015 in the Nature Reserve “Pädurea Domneascä”, 17 species of Chrysomelidae in 10 genera and 5 subfamilies were recorded. Republic of Moldova is located at the intersection of three biogeographical regions that explains the presence of Euro-Siberian, Transpalearctical, European, Mediterranean and Palearctic elements. Most of Chrysomelidae species included in the study are found in adjacent areas of the studied region. The Chrysomelidae fauna includes both forestry and grassland species.
