Abstract: In the forest ecosystem Horezu (Valcea county) they were recorded useful and also neutral insects, but in this paper are presented the pest insects in the forest vegetation: Lymantria dispar Linnaeus, 1758 (Erebidae Family), Tortrix viridana Latreille, 1803 (Tortricidae Family) and Coleophora laricella Hubner, 1817 (Coleophoridae Family).The purpose of this study was the monitoring the multiplication of the pest insects “en masse”, especially the defoliator insects and it present the abundance data per years with the evolution in time of the populations and also the biological control methods, by means of the pheromonal traps in the period between the years 2005-2019.The knowledge of the pest evolution had an important role in the forest protection and the researches made in the Forest District permitted the recording and the pest discover. The results had as a purpose to realize the prognosis for a short or a longer time of the evolution of the pests. The permanent research and the gathering of the data were important for the identification the characteristics of the pests and their infestation degree. It was established the number of the pheromonal traps for every pest and per every year, depending on the attack degree.
