Abstract

In the oak forests from Romania, the species of Geometridae develops regular outbreaks with decennal frequencies. This paper presents a historic of infestations on last 52 years (1960-2012) and analyzes the evolution trend of loopermoth populations in the last outbreak in Romania (2007-2010), depending by site conditions and forest stand characteristics. The mixed forests with common oak (Quercus robur) and sessile oak (Quercus petrea) as dominant species, placed on elevated plain, or on upper sides of the southern slopes, with ages over 80 years, shown favorable for developing ample outbreaks, with exponential growth rate of loopermoth populations.
