Invasive Insect Pests of Forests and Urban Trees in Russia: Origin, Pathways, Damage, and Management

Invasive alien insects cause serious ecological and economical losses around the world. Here, we review bionomics, modern ranges (and their dynamics), distribution pathways, monitoring, control measures of 14 insect species known to be important invasive emerging tree pests in forest urban ecosystems Russia: Leptoglossus occidentalis (Hemiptera: Heteroptera: Coreidae), Halyomorpha halys Pentatomidae), Corythucha arcuata Tingidae), Agrilus fleischeri, A. mali, planipennis, Lamprodila (Palmar) festiva (Coleoptera: Buprestidae), Ips amitinus, Polygraphus proximus Curculionidae: Scolytinae), Cydalima perspectalis (Lepidoptera: Crambidae), Acrocercops brongniardella, Cameraria ohridella, Phyllonorycter issikii, P. populifoliella Gracillariidae). We identified three major scenarios pest invasions country beyond: (1) a naturally conditioned range expansion, which results arrival new territory its further naturalization recipient region; (2) human-mediated, long-distance transfer naturalization; (3) widening pest’s trophic niche shift host plant(s) (commonly human-introduced) within native frequently followed by invasion regions.
