Detection and Monitoring of Alien Plant-Sucking Insect Species on the Black Sea Coast of Russia

The Black Sea coast of Russia is a recipient region for many alien insect pests. In 2018, we detected an invasive woolly whitefly Aleurothrixus floccosus (Maskell) (Homoptera: Aleyrodidae) attacking citruses in the agrocenoses and ornamental plantations in the region of Sochi. Furthermore, we clarified the secondary range of an alien whitefly, Aleuroclava aucubae (Kuwana) (Homoptera: Aleyrodidae) in the humid subtropics of Russia. Another plant-sucking invader, the western conifer seed bug Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) was revealed in the Black Sea coast of Crimea in 2019. Further distribution and trophic associations of these novel alien pests are discussed.
