The VIRTIGATION project, funded by the EU Horizon 2020 R&I programme, aims at developing rapid and lasting solutions to address emerging viral diseases caused by begomoviruses (whitefly-transmitted) and tobamoviruses (mechanically transmitted) on cucurbits and tomato in Northern Europe and the Mediterranean Basin, as well as at increasing knowledge to better control and manage the viral diseases. Project duration: June 2021 - May 2025 #TOLCNDV #TOBRFV #TYLCV

Psyllids (superfamily Psylloidea), also known as jumping plant lice, are a group of plant-sap sucking Hemiptera having significant pest status for crops, forest trees and ornamental plants. Only seven species of psyllids have been recorded in Luxembourg so far. An additional group of seven species has been recorded exclusively, based on the findings of their galls or specific plant deformations; but no mention exists in literature on the actual collection of the inducing insect in Luxembourg. To fill this knowledge gap, field collections were carried out during the years 2019-2020. In addition, samples from 1999-2000 stored in the wet collection of the Musée National d’Histoire Naturelle de Luxembourg were studied. This research, in combination with information coming from literature, allowed us to list 48 species of the families Aphalaridae (5 species), Liviidae (5), Psyllidae (24) and Triozidae (14), though the presence of one species within the last family ( Trioza rhamni ) needs to be confirmed. Brief information on geographical distribution, biology and (if available) illustrations of diagnostic characters are provided on the psyllid species detected in Luxembourg so far.
Although many crops have developed several adaptation mechanisms that allow them to defend against limiting factors, some biotic and abiotic stresses may cause reversible or irreversible changes in plants. Among the biotic stresses, the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is probably one of the main important pests that negatively affect several vegetable crops that are grown in greenhouses. The present study evaluated its impact on the morphology and physiology of two solanaceous plants, i.e., tomato (Solanum lycopersicum L.) and eggplant (S. melongena L.), under laboratory conditions. The results showed that, for tomatoes, plant height, shoot dry weight, leaf area, and indirect chlorophyll content were strongly reduced in infested plants, compared to the uninfested control, by 39.36%, 32.37%, 61.01%, and 37.85%, respectively. The same has been shown for eggplant, although the reduction percentages of plant height, root dry weight, and indirect chlorophyll content were less marked (i.e., 16.15%, 31.65%, and 11.39%, respectively). These results could represent interesting information for a better understanding of the B. tabaci influence on plant growth, as well as for the development of management strategies to successfully control its infestations in a cropping system.
en This paper provides a first report of Aleurocanthus camelliae, the Camellia spiny whitefly, from Italy. The pest was found on plants of Camellia spp. grown in the nursery. Brief morphological and biological information is provided on this whitefly, as well as some considerations on the phytosanitary measures to be adopted to reduce the potential risk of its spread on ornamental plants in Europe and the EPPO region. Premier signalement d'Aleurocanthus camelliae Kanmiya & Kasai, 2011 (Hemiptera, Aleyrodidae) en Italie, sur des plants ornementaux de Camellia spp fr Cet article présente le premier signalement de l’aleurode Aleurocanthus camelliae en Italie. Cet organisme nuisible a été signalé sur des plants de Camellia spp. cultivés en pépinière. Cet article présente brièvement des informations sur la morphologie et la biologie de cet aleurode, ainsi que des considérations sur les mesures phytosanitaires à adopter pour réduire son risque de dissémination sur plantes ornementales en Europe et dans la région OEPP. Первое обнаружение Aleurocanthus camelliae Kanmiya & Kasai, 2011 (Hemiptera, Aleyrodidae) в Италии на декоративных растениях Camellia spp ru В данной работе представлено первое сообщение о щетинистой камелиевой белокрылке Aleurocanthus camelliae, из Италии. Вредный организм был найден на растениях Camellia spp., выращиваемых в питомнике. По этой белокрылке представлена краткая морфологическая и биологическая информация, а также некоторые соображения по фитосанитарным мерам, которые должны быть приняты для снижения потенциального риска ее распространения на декоративные растения в Европе и регионе ЕОКЗР.
