Alien invasive species not only have adverse environmental impacts, they may also pose socioeconomic and human health threats. The increase in detected non-native (alien) and cryptogenic species, followed by the necessity for up-to-date scientific information on biological invasions, prompted a thorough literature investigation on the non-native entomofauna of Greece. Supplementing previous studies concerning Europe and Greece, a checklist for the non-native insect species of the country is provided, while their number is elevated from 266 to 469. Current trends regarding species richness and taxonomy, deliberate or accidental means of introduction, as well as their native range and trophic preferences are analysed and discussed. This publication illustrates the current state of non-native insects of Greece, highlighting the need for an effective early warning system integrated in national phytosanitary legislation, survey protocols and strategies towards the eradication and mitigation of their detrimental impacts.

Summary The study concerns the first records for the presence of the box tree moth Cydalima perspectalis in Greece and subsequent infestations on ornamental box trees in urban environment. Adults of the pest were first spotted in six locations around the country from October 2013 until April 2015, when infestation was also detected (mid April). The pest was found infesting plants of Buxus sempervirens in several private and public gardens and parks in the urban environment of Kifissia, Attica. Possible introduction scenarios, as well as preventive and control measures are discussed.

The Egyptian fruit bat (Rousettus aegyptiacus) is a pteropodid species with a large part of its range in the Palearctic region. It has a quite discontinuous range from sub-Saharan Africa to NW India, including SW Turkey. In this note we present the first record of the Egyptian fruit bat in Greek territory, observed during a zoological expedition on the island of Kastellorizo (Dodecanese, Greece). At least three specimens were observed foraging a white mulberry in the town of Megisti on May 4 2017, but no individual was spotted during a summer expedition in August 2017.
