Ladybirds (Coleoptera: Coccinellidae) are an important beneficial group that, as other insects, are negatively affected by many human-mediated threats, including climate change, agricultural intensification, habitat loss, pollution, and biological invasions. Ecological impacts from these threats have altered the richness, abundance, and distributio...

Hesperomyces virescens (Ascomycota, Laboulbeniales), a fungal ectoparasite, is thus far reported on Harmonia axyridis from five continents: North and South America, Europe, Africa, and Asia. While it is known that He. virescens can cause mortality of Ha. axyridis under laboratory conditions, the role of biotic and abiotic factors in influencing the...

The capability of a non-native species to withstand adverse weather is indicative of its establishment in a novel area. An unusually cold winter of 2016/2017 that occurred in the West Carpathians of Slovakia and other regions within Europe provided an opportunity to indirectly assess survival of the invasive ambrosia beetle Xylosandrus germanus (Co...

Wildlife observations submitted by volunteers through citizen science initiatives are increasingly used within research and policy. Ladybirds are popular and charismatic insects, with most species being relatively easy to identify from photographs. Therefore, they are considered an appropriate taxonomic group for engaging people through citizen sci...

In 2016–2019, seasonal changes in the abundance of the harlequin ladybird Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) were established in the city center of Prague, Central Europe, and in its outskirts. Adults were sampled from lime trees ( Tilia spp.) at regular intervals throughout the growing season. The abundance of H. axyridis paral...

In temperate forests within Europe, early-flushing (EF) deciduous trees are often heavily infested by early spring leaf-eating Lepidoptera, while late-flushing (LF) trees are better protected in a phenological manner against such heavy infestations, as spring moth larvae begin to appear before their bud burst. The associational effects of EF trees...

The double-spined bark beetle Ips duplicatus (Coleoptera: Curculionidae, Scolytinae) is an invasive forest pest having a broad range of coniferous hosts within Europe. We found this species to be also developing in the Serbian spruce Picea omorika. Ips duplicatus infested 14 (52%) of 27 P. omorika mature trees in an arboretum garden in northern Slo...

The Harlequin ladybird Harmonia axyridis Pallas, native to eastern Asia, is an invasive, non-native species that has recently achieved an almost worldwide distribution. A conspicuous feature of this species is colour polymorphism of the elytra. In its native area, the populations consist of a recessive non-melanic morph, several dominant melanic mo...

Invasive organisms represent great threats to ecosystems and great challenges to forest management. In Europe, the black timber bark beetle (Xylosandrus germanus) is an invasive secondary pest that mostly attacks the logs of felled trees. We showed the invasion history for Europe and using many local surveys, we summarize the current distribution a...

Species within the group of winter moths (Geometridae) are important oak defoliators in European forests. Adults of these species emerge either in late autumn ('autumn species') or in early spring ('spring species'), and caterpillars of both 'autumn' and 'spring' species appear in spring. The abundance of adults assessed by regular monitoring allow...

The box tree moth, Cydalima perspectalis (Lepidoptera: Crambidae), is native to East Asia and was introduced in Europe more than a decade ago. It causes severe damage to box trees (Buxus spp.) in both urban and natural habitats. The occurrence of this invasive pest in southeastern Europe has not been documented in a comprehensive way yet. The main...

Excessive mortality of Scots pine (Pinus sylvestris) trees has recently been observed in the Záhorská nížina lowland in western Slovakia, Central Europe. Continuous drought, bark beetles and blue-stain fungi are likely to play a crucial role in this dieback of pines in a warm sandy area. Two blue-stain fungi, Ophiostoma ips and Ophiostoma minus, we...

Attraction of bark beetles (Coleoptera: Scolytidae) to Norway spruce was studied in the timberline forest in Tatra Mountains, West Carpathians, Central Europe, by trapping bark beetles in flight interception traps fixed to the lower parts of the 18 trunks of spruce trees, and by recording colonizations of bark beetles on those trees in 2004. The tr...

Blue spruce has locally been introduced to the forests in Central Europe. It was considered as a suitable substitute tree species in areas where afforestation with the native Norway spruce had not been successful, e.g. in areas heavily affected by air pollution. Young plantations of blue spruce were healthy, without serious insect damage. We studie...
