Thrips (Thysanoptera) from dead aspen (Populus tremula) trees in Eastern Finland

Abstract

Thrips were collected from dead aspens (Populus tremula) using trunk-window traps at two forest areas in Eastern Finland during 2001 and 2002.We collected 156 individuals of 23 species (15 Terebrantia; 8 Tubulifera). Four of the species – all Tubulifera – were previously unknown from Finland, and two unknown from Fennoscandia, indicating that the thrips fauna of this area is poorly known. Three of these species, Hoplothrips carpathicus Pelikán, Liophloeothrips glaber Priesner and L. hungaricus (Priesner) are fungivores, while Lispothrips crassipes (Jablonowski) is an arboreal herbivore. The species assemblages of the study areas are compared and a list presented of all species collected.
