& Key message The emerald ash borer (Agrilus planipennis Fairmaire), an alien pest native to Asia, has spread to Ukraine and 16 regions of European Russia. It severely damages Fraxinus pennsylvanica Marsh. introduced from North America, but serious damage to European ash (Fraxinus excelsior L.) has not been detected in forests. & Context The first detection of A. planipennis in European Russia was in Moscow in 2003, when it began to spread. & Aims To determine the range of A. planipennis as of 2020. & Methods In 2017-2020, our Russian-Ukrainian research team examined > 7000 F. pennsylvanica trees and > 2500 F. excelsior trees in 84 localities of European Russia, Ukraine, and Belarus. & Results The current range exceeds the area of Spain and includes the Luhansk region of Ukraine and 16 regions of ER:
Bad and good news for ash trees in Europe: alien pest Agrilus planipennis has spread to Ukraine and the 1 south of European Russia, but serious damage of Fraxinus excelsior in the forests is not detected 2 3
The mature larvae and pupae of Anthonomus (Anthonomidius) rubripes Gyllenhal, A. (s. str.) incurvus (Panzer), A. (s. str.) conspersus Desbrochers des Loges, and A. (s. str.) latior Pic, are described for the first time. The immature stages of A. (Anthomorphus) pinivorax Silfverberg, A. (s. str.) pedicularius (Linnaeus) (larva only), A. (s. str.) rubi (Herbst) are redescribed. The previous description of A. (s. str.) pomorum (Linnaeus) is checked and updated with new data. Keys for the identification of species of 9 larvae and 10 pupae of Palaearctic species are presented. Additional information on the biology of some species is provided. Crataegus pinnatifida is established as a host plant for the first time for A. (s. str.) latior.
This paper targets the nearly cosmopolitan weevil subfamily Lixinae. A phylogenetic analysis of one mitochondrial and two nuclear DNA fragments obtained from 87 Lixinae and 49 outgroup terminals strongly supports the monophyly of the subfamily. The molytine tribe Mecysolobini is the likeliest sister group of Lixinae; adults of both taxa share the likely synapomorphic condition of the greatly shortened labial palpi. Phylogenetic relationships within the subfamily are poorly resolved. None of three Lixinae tribes is recovered as monophyletic. The subfamily’s oldest dichotomy is formed by a clade of two genera Rhabdorrhynchus plus Pachycerus sister to the rest of the subfamily. The genera Chromonotus, Larinus, Lixus, and Stephanocleonus are recovered as non-monophyletic. The genera Asproparthenis, Chromonotus, and Maximus form a strongly supported clade. The genus Eumecops is the likeliest sister to the clade formed by the genera Stephanocleonus plus Coniocleonus. The cleonine genus Scaphomorphus is a sister to a subset of externally most similar species of the genus Lixus; the same clade likely includes the genus Lixoglyptus not represented in the analysis. As an aside we provide a short summary of active flight in adult Cleonini.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
