Phyllophagous insects that feed on the leaves of trees and shrubs in deciduous forests cause qualitative and quantitative damage to these natural ecosystems, true sources of oxygen. The current study aims to be an update of the information on the range of important pests in Romanian deciduous forests with continental extrapolation. An evaluation of the existing database (mainly from electronic sources but also from the physical bibliography) clearly shows that most of the pest species that are currently a problem for all deciduous forests in any area of the country belong to the orders Hemiptera (10) and Lepidoptera (8). Besides these, other categories of Coleoptera (2), Diptera (2), Orthoptera and Hymenoptera (1) were quantified. Stink bugs, aphids, tingids and cycads constituted the Hemiptera group with 41.66% of the total pests and Lepidoptera (which includes both moths and large butterflies) represented 33.33%. The remaining 25.31% is composed of leaf beetles, mining flies, bush-crickets and sawflies. All of these have the ability, both individually and together, to cause tree loss and to spread and infest new areas. Updating databases and initiating periodic monitoring activities in all forests, regardless of region, are ways of raising awareness of potential economic losses and, first of all, that they lead to the weakening of the main oxygen-producing sources.
