Abstract

The main areas affected by Lymantria dispar (Linnaeus, 1758) (Lepidoptera: Erebidae) recorded in Girona and Barcelona provinces throughout the epidemic outbreak episode of 2017-2021 are detailed, indicating locality, defoliated areas and GPS coordinates. A historical list of the attacks and defoliations recorded in Catalonia since 1886 is also included. Similarly, records of the epidemic outbreaks that have occurred in the Balearic Islands, in Menorca (since 1869 and during 2000- 2022) and in Mallorca (during 2005-2022), as well as in continental Spain, with special attention to Cádiz and Málaga (from 1953 to 2022) are reported. Finally, attacks and defoliations of L. dispar on Pinus radiata D. Don forest plantations in Spain and Catalonia are also reported.
