Bella, Salvatore
Summary The spread of invasive pests is an important topic in pest control and early detection is crucial for containment of invasive aliens. In this study the results of recent surveys on alien insects of ornamental urban plants in Portugal are reported. Overall, 13 alien species associated with allochthonous ornamental plants were recorded. Seven of these pests are new to the Portuguese fauna: Tinocallis kahawaluokalani (Kirkaldy); Illinoia liriodendri (Monell); Appendiseta robiniae (Gillette) (Hemiptera: Aphididae); Acizzia jamatonica (Kuwayama) (Hemiptera: Psyllidae); Dasineura gleditchiae (Osten Sacken); Obolodiplosis robiniae (Haldeman) (Diptera: Cecidomyiidae); and Phytoliriomyza jacarandae Steyskal & Spencer (Diptera: Agromyzidae). Additional distribution data are also provided for other recently introduced alien pests in Portugal: Myzocallis (Lineomyzocallis) walshii (Monell) (Hemiptera: Aphididae); Platycorypha nigrivirga Burckhardt; Glycaspis brimblecombei Moore (Hemiptera: Psyllidae); Calophya schini Tuthill (Hemiptera: Calophyidae); Corythucha ciliata (Say) (Hemiptera: Tingidae); and Lantanophaga pusillidactylus (Walker) (Lepidoptera: Pterophoridae). Three species in particular (Illinoia liriodendri , Obolodiplosis robiniae and Phytoliriomyza jacarandae) were not previously found in the Iberian Peninsula. Details on current distribution, host plants and biological remarks are given for each species. Possible origin areas, pathways and impacts are also discussed.
