On the quantitative criteria of subspecies in insects. Case study of Entomoscelis adonidis (Coleoptera: Chrysomelidae) in European Russia and the Caucasus.

Many insect subspecies are described without a statistical assessment of differences. In this work, an attempt is made to statistically process the morphological differences of some recently described subspecies. In this regard, a taxonomic review of Entomoscelis adonidis (Pallas, 1771) (Coleoptera, Chrysomelidae) and related taxa described from European Russia and the Caucasus is presented.

Low Heat Availability Could Limit the Potential Spread of the Emerald Ash Borer to Northern Europe (Prognosis Based on Growing Degree Days per Year).

Emerald ash borer (Coleoptera: Buprestidae) is one of 20 priority quarantine pests of the European Union. It is native to Asia and is established in the USA, Canada, European Russia, and Ukraine. We made the first prognosis of the potential range of in Europe based on heat availability.

Invasive Agricultural Pest (Diptera, Drosophilidae) Appeared in the Russian Caucasus.

Spotted-wing drosophila (Matsumura) is one of the most important invasive pests of fruit and wine production worldwide. This species feeds on spp., spp.

History of the Biodiversity of Ladybirds (Coccinellidae) at the Black Sea Coast of the Russian Caucasus in the Last 120 Years-Does the Landscape Transformation and Establishment of Have an Impact?

Studies of the history of regional insect fauna are important for understanding the changes in ecosystems. We analyzed the dynamics of ladybird fauna at the main sea resort of Russia over a period of 120 years to determine the following: (1) what species disappeared and what species appeared during landscape transformation; (2) what alien species introduced for pest control have been observed to date; and (3) whether the establishment of the global invader (Coccinellidae) caused the extinction of some ladybird species in the Caucasus. We examined specimens collected by us and 54 other collectors including specimens from old museum collections and detected 62 species, 50 of which were collected in recent years (2011-2020).

Rigorous Morphological Studies Confirm That the Classical Object of Pest Control Is the Same Species as (Coleoptera: Coccinellidae).

The ladybug , which was described in Japan, has been used for biological control of pests for 100 years. was recently synonymized with described in Europe. The synonymy was based on the examination of few specimens.

Minimum Winter Temperature as a Limiting Factor of the Potential Spread of , an Alien Pest of Ash Trees, in Europe.

The emerald ash borer, EAB () is a devastating alien pest of ash trees. It is spreading in European Russia and Ukraine and will appear in other European countries. Our aim was to determine the regions of Europe where the winter temperature drops low enough to prevent establishment.

Record of the Emerald Ash Borer () in Ukraine is Confirmed.

(Coleoptera: Buprestidae) is a devastating invasive pest of ash trees. This wood-boring insect is native to Asia and established in European Russia about 20 years ago. It severely damages plantations and quickly spreads.

Coinvasion by the ladybird Harmonia axyridis (Coleoptera: Coccinellidae) and its parasites, Hesperomyces virescens (Ascomycota: Laboulbeniales) and Parasitylenchus bifurcatus (Nematoda: Tylenchida, Allantonematidae), in the Caucasus.

The study of parasites in recently established populations of invasive species can shed light on the sources of invasion and possible indirect interactions between the alien species and native ones. We studied parasites of the global invader Harmonia axyridis (Coleoptera: Coccinellidae) in the Caucasus. In 2012, the first established population of Ha.

Modeling long-distance dispersal of emerald ash borer in European Russia and prognosis of spread of this pest to neighboring countries within next 5 years.

Aim: To develop an approach to model the spatial dynamics of emerald ash borer (Coleoptera: Buprestidae) in European Russia. This tree-killing pest was detected in Moscow 15 years ago and began to spread, posing a threat to ashes all over Europe. The aim was to determine its probable current range and to evaluate the probability of its dispersal to neighboring countries within the next 5 years.

Alien leaf beetles (Coleoptera, Chrysomelidae) of European Russia and some general tendencies of leaf beetle invasions.

Invasions of leaf beetles can cause tremendous economic consequences because some of these insects become major pests in invaded territories. We present the first inventory of alien Chrysomelidae of European Russia that appeared in the region in the 20th and 21st centuries (9 species) with analysis of the history of their invasions and detailed maps of distribution. This case study revealed some general tendencies of invasions of leaf beetles: (1) Recently, a dramatic increase in the rate of Chrysomelidae invasions is observed, which reflects the increase in international trade of living plants; (2) Alien leaf beetles can spread quickly, occupying almost all of Europe within several decades; (3) When the range of some leaf beetle species is quickly expanding, or when the species has been recorded established somewhere outside the native range, this species should be regarded as a potential invader worldwide.

World checklist of flea-beetles of the genus Epitrix (Coleoptera: Chrysomelidae: Galerucinae: Alticini).

The world checklist of the genus Epitrix (Coleoptera: Chrysomelidae: Galerucinae: Alticini) is necessary, since many species of this genus are serious pests of potato and other Solanaceae, and since some species have been inadvertedly introduced from one continent to another and established. We have compiled the catalogue of all species described to date. There are 162 species and 11 subspecies in the world.

Key to Holarctic species of Epitrix flea beetles (Coleoptera: Chrysomelidae: Galerucinae: Alticini) with review of their distribution, host plants and history of invasions.

The genus Epitrix Foudras, 1860a has a worldwide distribution. Some species of Epitrix are major pests of potato, tomato, eggplant, tobacco and other plants in North America and Europe. Some pest species have been inadvertently introduced from North America to Europe, from Europe to North America and from both continents to some islands in Atlantic and Pacific oceans.
