Die feinstruktur der fl�igelschuppen einiger Lycaeniden (Insecta, Lepidoptera)
1970
Green, blue and violet colours of Lycaenidae examined by us — with the exception of Rapala arata (Theclinae) — are due to iridescent scales which are arranged before a dark background. The iridescent scales are constructed according to the Urania-type and may be diverted from pigmented scales by laying in equidistant lamellae and little cuticular bars, which maintain the distance between the lamellae. The ribs in the longitudinal axis of the scales contain lamellae and bars only in the Plebejinae, in Lycaeninae and Theclinae they are small and sit on the plain upperside of the scale with a narrow base.
BCL-xL, a Mitochondrial Protein Involved in Successful Aging: From C. elegans to Human Centenarians
2020
B-Cell Lymphoma-extra-large (BCL-xL) is involved in longevity and successful aging, which indicates a role for BCL-xL in cell survival pathway regulation. Beyond its well described role as an inhibitor of apoptosis by preventing cytochrome c release, BCL-xL has also been related, indirectly, to autophagy and senescence pathways. Although in these latter cases, BCL-xL has dual roles, either activating or inhibiting, depending on the cell type and the specific conditions. Taken together, all these findings suggest a precise mechanism of action for BCL-xL, able to regulate the crosstalk between apoptosis, autophagy, and senescence, thus promoting cell survival or cell death. All three pathways…
Antibacterial activity of Borago officinalis and Brassica juncea aqueous extracts evaluated in vitro and in situ using different food model systems
2014
The present study was undertaken to characterize the antibacterial activity of the aqueous extracts (AEs) obtained from the leaves of Borago officinalis L. and Brassica juncea L. The antagonistic activity was evaluated against several bacteria (42 strains of Listeria monocytogenes, 35 strains of Staphylococcus aureus, 38 strains of Enterobacter spp. and 18 strains of Salmonella enterica) commonly associated with foodborne diseases by paper disc diffusion method. The susceptibility to the plant extracts was strain specific. Thirty-five strains (7 L. monocytogenes, 11 S. aureus, 1 S. Enteritidis, 1 S. Veneziana, 7 Enterobacter hormaechei, 5 Enterobacter cloacae, 1 Enterobacter sakazakii and 2…
Order Orthoptera

Authors report an annotated checklist of Orthoptera of UAE, based on their collecting and bibliography.
New or interesting records of Palearctic Orthoptera (Insecta).
2010
The author reports some interesting Orthoptera from Palearctic region, namely: Pezodrymadusa subinermis Karabag, 1961, Phytodrymadusa viridipennis (Shchekanovtsev, 1915), Paranocarodes sulcatus (I. Bolivar, 1912) from Armenia, Scintharista notabilis notabilis (Walker, 1870) from Azores, Brachycrotaphus tryxalicerus (Fischer, 1853) from Egypt, and Euchorthippus declivus (Brisout, 1848) from Sardinia (Italy). Additionally, he establishes the synonymies Eupholidoptera peneri Kaltenbach, 1969 = Uvarovistia rammei Katbeh Bader et Massa, 2001 from Jordan; Stenobothrus ursulae Nadig, 1986 = S. nadigi La Greca, 1986 from Piedmont and Aosta Valley (Italy); Pterolepis pedata A. Costa, 1882 = Rhacocle…
Scolitidi e loro parassitoidi sfarfallati da piante esca di pino laricio e pino d'Aleppo sull'Etna e sui monti Iblei.
2011
In due differenti pinete della Sicilia in cui si sono registrati recenti attacchi di scolitidi, in collaborazione con l’Azienda Foreste Demaniali, a fine autunno 2008 e 2009 alcune piante sono state abbattute e lasciate sul letto di caduta, intere e con chioma, fino alla primavera successiva in attesa della colonizzazione di coleotteri scolitidi. Nel demanio Sparano, (Noto, SR) a 620 m s.l.m., sui monti Iblei sono state abbattute piante esca di Pinus halepensis, mentre in due località del Parco dell’Etna, Passo Silletta (1200 m s.l.m.) e Secondo Monte (1600 m s.l.m.), sono state abbattute piante esca di Pinus laricio. A maggio dell’anno successivo, parti di fusto di diametro crescente lungh…
The biological control applied in Citrus orchards against harmful exotic pests in Sicily (Italy)
2018
The citrus groves are injured by infestations caused by indigenous species or old and new phytophagous introduced. Several problems have found in the biological control a optimal solution that allowed a considerable reduction in the use of chemical products. In fact, applications of programs using biological methods has been more successful on citrus than in any other cropping system. Sicily (Italy), due to its location in the Mediterranean Sea, represents an island particularly rich flora and fauna with a characteristic biodiversity different from those of other countries and regions of Italy. It produces about 60% of the national citrus production with more areas of organic citrus groves.…
European Red List of Grasshoppers, Crickets and Bush-crickets
2016
The European Red List is a review of the conservation status of European species according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level, so that appropriate conservation action can be taken to improve their status. This Red List publication summarises results for all hitherto described native European Orthoptera species (grasshoppers, crickets and bush-crickets). All Orthoptera species (grasshoppers, crickets and bushcrickets) native to or naturalised in Europe before AD 1500 (a total of 1,082 species), have been assessed in this Red List. The geographical scope is continent-wide, extending from Iceland in the…
Predatory performance of two Mediterranean phytoseiid species, Typhlodromus laurentii and Typhlodromus rhenanoides fed on eggs of Panonychus citri an…
2013
Laboratory trials were carried out to determine the predatory capacity of two endemic to the Mediterranean area phytoseiid mites Typhlodromus (Typhlodromus) laurentii Ragusa et Swirski and Typhlodromus (Anthoseius) rhenanoides Athias-Henriot (Parasitiformes Phytoseiidae) upon the eggs of the two most important tetranychids damaging Citrus orchards in Sicily: Tetranychus urticae Koch and Panonychus citri (McGregor) (Acariformes Tetranychidae). The research aimed at investigating the predatory behaviour of the phytoseiids upon the prey stage considered the most vulnerable. The predation rate of the two phytoseiid species was different on the two prey eggs, both in every observation day and fo…
Predation of Typhlodromus longilaterus Athias-Henriot (Parasitiformes, Phytoseiidae) females on eggs and juveniles of the tetranychid mites Tetranych…
2013
Typhlodromus longilaterus is a generalist phytoseiid mite described by Athias-Henriot in 1957 and commonly found in Israel on spontaneous herbaceous plants. As very little is known about this species, the present study reports preliminary results on the predation capacity of phytoseiid females on eggs and juveniles of two tetranychid mites very common in the Mediterranean area, Tetranychus urticae and Panonychus citri. After 24 hours the phytoseiid females preyed on 15% of offered eggs of both tetranychids, while the prey ratio was higher on T. urticae eggs after this period (33.4% and 33.5% vs 20.8% and 16.2% after 2 and 3 days for T. urticae and P. citri respectively). The phytoseiid show…
