During August 2015, the weevil Gonipterus scutellatus complex (Coleoptera Curculionidae), a pest of Eucalyptus spp., was found for the first time in Sicily. According to our surveys, Eucalyptus globulus was the only infested tree species. Source

Invasive species are a significant threat to affected ecosystems, having serious environmental, economic and social impacts. The maritime pine bast scale, Matsucoccus feytaudi Ducasse (Hemiptera: Matsucoccidae), causes serious damage to Pinus pinaster forests in SE France, Corsica and Italy where it has been introduced. This study illustrates the adaptive management plan implemented in the Migliarino, San Rossore, Massaciuccoli Regional Natural Park in Tuscany, Italy, where M. feytaudi arrived in 2004, leading to the decay of local P. pinaster stands. The management programme, aimed at slowing the establishment and growth of M. feytaudi, was carried out in the main sector of the park, Tenuta di San Rossore, to retard the destruction of the P. pinaster coastal strip protecting the more internal woodland from sea salt and to allow replacement of P. pinaster trees with a more stable broad-leaved wood. The combined use of mass trapping and silvicultural interventions, applied in a targeted manner according to distribution maps of pest captures and damage, helped to delay forest destruction compared with a nearby unmanaged area of the park Tenuta di Tombolo. Although M. feytaudi continued to spread during the management period, the populations remained at low levels for 6 years, showing a marked increase in 2012. During this period, the P. pinaster stands were reduced from 320 to 249 ha. The final result of this ongoing gradual conversion process will be transformation of the P. pinaster forest into Holm oak woods and Mediterranean shrub land, while P. pinaster will survive as clusters or blocks of trees.

A chalconoid analogue, 1,3,5-benzentriol 2-[(2S,3R)-3-(3,4-dihydroxylphenyl)-2,3-dihydroxylpropyl], named filiferol (1), has been isolated and purified for the first time from the leaf basal tissues of the palm species Washingtoniafilifera. The chemical structure of the isolated compound has been elucidated unambiguously by spectroscopic and chemical methods. Filiferol has been based on a flavonol structure with the reduction of the common flavonoid keto group to give an unprecedented methylene carbon on the three carbon chain. An analogous compound with S stereochemistry at C3 has been obtained as synthetic intermediate for developing an enantioselective synthesis of (2R,3S)-(+)-catechin. Even though 1 proved to be deprived of antifungal properties, it displays a very effective larvicidal activity against Red Palm Weevil, Rhynchophorus ferrugineus, an important pest affecting cultivated and ornamental palms. 1 has been isolated from leaf tissues of W. filifera, a species resistant to this pest, but this molecule seems instead undetectable in tissues of other palm species susceptible to the parasite. The presence of 1 could therefore account for W. filifera natural resistance to the attacks of the Red Palm Weevil (R. ferrugineus). © 2015 Elsevier Ltd. All rights reserved. Source

The Authors report on the discovery in South Cyprus of the aphid Cinara (Cinara) cedri Mimeur collected on the endemic cedar, Cedrus brevifolia (Hooker fil.) Henry. This is the first record of the lacnid in Cyprus. The ecological aspects of the cedar and its interaction with the related aphid species are discubed. The Authors suggest the hypothesis that the aphid may be co-endemic with its host conifer since it shows significant morphological differences compared with specimens from other European regions. The question whether the Cyprus cedar aphid can be injurious or not to its host plant is debated as well. The exact taxonomic position of this lacnid is currently under investigation. Source
