Abstract

A review is reported in the present paper on invasive alien insects introduced in Sicily on Eucalyptustrees, togeth-er with unpublished results from recent surveys. As to the latter ones, observations were conducted especially onThaumastocoris peregrinus(Carpintero & Dellapé) (Hemiptera, Thaumastocoridae), the most recently introducedspecies. Overall, eight alien insect pests have been accidentally introduced in the island on Eucalyptus,belonging to theorders Hemiptera (Aphalaridae, 2 spp.; Thaumastocoridae, 1 sp.), Coleoptera (Cerambycidae, 2 spp.; Curculionidae, 1sp.) and Hymenoptera (Eulophidae, 2 spp.). Two encyrtid parasitoids, Avetianella longoiSiscaro and Psyllaephagus bli-teusRiek, obtained from Phoracanthaspp. and Glycaspis brimblecombeiMoore respectively, and Closteroceruschamaeleon(Girault) (Hymenoptera, Eulophidae) attacking Ophelimus maskelli(Ashmead), are also reported.Detailson current distribution, host plants, morphological and biological remarks are given for each species.
