This paper includes the analysis of species diversity and importance of some invertebrates (Collembola, Homoptera and Coleoptera) for the forest ecosystems. At the present time in the Republic of Moldova there can be found 350 species of Homoptera (aphids). Among them – 145 produced “honey dew” for 31 species of ants. Th ey represented source of food for several species of insects. Th ere are some species of aphids that are pests of agricultural plants, but they are not dangerous for the forests. Coleopterans have been studied in the landscape reserve “Codrii Tigheciului” (160 species) and in other forests (20 edaphic and dendrophylous species) collected in the central area and northern zones of the Republic of Moldova. After the trophic spectrum the recorded phytophagous coleopterans aren’t dangerous for forest ecosystems, although in drought years the dendrophylous species Galerucella luteola was very abundant in elm forest. In forest ecosystems were registered various trophic groups of coleopterans: predatory, necrophagous, coprophagous and saprophagous, which have a positive role in the maintenance of sanitary status of woods. An important role for forest ecosystems is also represented by the colembolans that decompose the organic matter and participate to the formation of the humus and soil structure. Collembolan fauna was analyzed on the basis of material collected in the State Nature Reserve “Plaiul Fagului”, where 118 species were recorded, which constitute more than half of total number of collembolan species registered for the Republic of Moldova. |
