Alien whiteflies (Hemiptera: Aleyrodidae) of Europe recorded in Croatia [Conference poster].

Abstract

Whiteflies belong to the order Hemiptera and comprise a single superfamily, Aleyrodoidea, within the suborder Sternorrhyncha. They are all placed in a single family, Aleyrodidae with 1556 described species accommodated in 161 genera. The whitefly fauna of Europe and the Mediterranean Basin comprises 56 species that are considered to be native or naturalized, accommodated within 25 genera. Alien species are defined as species living outside of their natural range and outside of their natural dispersal potential. At present, the alien species represent 39% of the total whitefly fauna occurring in Europe. Whiteflies are distributed throughout the major zoogeographical regions of the World, with their greatest diversity in tropical and south temperate regions. The trade of exotic trees and ornamentals is responsible for many accidental introductions of insects to countries far away from their native area. Most alien species of whiteflies were accidentally introduced with their host plant. The starting point for compiling the list of alien whitefly species in Croatia was a book "Alien Terrestrial Arthropods of Europe" and database DAISIE. A list of alien whiteflies in Croatia was made by searching of agricultural, forestry and taxonomic entomological peer-reviewed literature and the latest check list of whiteflies in Croatia. The check list of whiteflies in Croatia published in 2008, contains 31 species belonging to 18 genera. According to DAISIE list, seven of them are alien to Europe. These are the following species: Aleurolobus olivinus Silvestri 1911, Aleurothrixus floccosus Maskell 1896, Bemisia afer Priesner & Hosny 1934, Bemisia tabaci Gennadius 1889, Dialeurodes citri Ashmead 1885, Massilieurodes chittendeni Laing 1928 and Trialeurodes vaporariorum Westwood 1856. Two alien whitefly species recorded for the first time in Croatia after 2008 and not presented in DAISIE (2009) are Aleurocanthus spiniferus Quaintance 1903 detected in 2012 and Aleuroclava aucubae (Kuwana 1911) found in 2013.
