The mantids of Caucasus.
2008
The male of Hierodula trancaucasica Brunner von Wattenwyl, 1878, is described here. The external morphology and shape of genitalia are analysed. A comparison with previous data and some biogeographical considerations on Paramantini are given.
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…
REVISIONE PRELIMINARE DELLA BIODIVERSITÀ ENTOMOLOGICA DELL’ISOLA DI LAMPEDUSA (SICILIA - ITALIA) PRELIMINARY REVISION OF ENTOMOLOGICAL BIODIVERSITY I…
2013
Lampedusa è un'isola appartenente all'arcipelago delle Pelagie, che è particolarmente interessante per l'aspetto faunistico, in quanto crocevia tra la fauna Europea e Africana. Gli insetti, per la loro abbondanza e diversità in natura, rappresentano una classe nel regno animale particolarmente utile per studiare la biodiversità e i fenomeni di migrazione o emigrazione delle specie, e per valutare inoltre eventuali cambiamenti climatici. Allo stato attuale i dati sull'entomofauna non sono organici e sono riportati in modo spesso frammentario, e la check-list più completa disponibile è datata 1995, quasi venti anni fa. Lo scopo di questo lavoro è stato quello di impiegare nuove tecniche di ri…
The gut bacterial community of the red palm weevil Rhynchophorus ferrugineus (Olivier, Coleoptera, Curculionidae) larvae
2011
The red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier, Coleoptera, Curculionidae) is the major pest of palm trees in the Mediterranean area. Damages are caused mainly by the endophytophagous larvae that consume the palm tender soft tissues making galleries and producing a wet “frass” with a characteristic fermented odour. The culturable bacterial community associated to the frass produced by RPW larvae inside Phoenix canariensis trees is mainly composed of facultative anaerobe gamma-proteobacteria that have their closest phylogenetic relatives in the gut microbiome of other endophytophagous and xilophagous coleopteran as bark beetles and other plant biomass-degrading insects (leaf-c…
PIANTE AROMATICHE E MEDICINALI: L’ ENTOMOCENOSI DEL CAPPERO IN SICILIA
2005
Guilds of herbivore insects of medicinal and aromatic plants are generally composed by poliphagous insects that only occasionally are present at high infestation levels. In this paper the main insect pests observed on Capper spinosa (L.) in Sicily are described. The key pests of this crop are Capparimyia savastani (Martelli) – (Diptera: Tephritidae), Asphondylia gennadii (Marchal) (Diptera: Cecidomyiidae), and, the painted bug Bagrada hilaris (Burmeister) (Heteroptera: Pentatomidae). Infestations of other insect pests are also occasionally recorded as the case of the southern green stink bug, Nezara viridula (L.) (Heteroptera: Pentatomidae), in the island of Ustica; the cabbage butterfly, P…
Scelionidae (Hymenoptera: Platygastroidea) recorded in Italy and their known hosts.
2020
Scelionidi (Hymenoptera: Platygastroidea) segnalati per l’Italia e loro ospiti noti. Il seguente lavoro propone una revisione della checklist italiana della famiglia Scelionidae dopo quella proposta da Bin et al. (1995). Viene inoltre fornito l’elenco delle specie di ospiti di Insecta e Arachnida individuate nel lavoro di raccolta bibliografica. In totale sono riportati 38 generi di scelionidi per l’Italia con 181 specie di cui 58 riportano anche gli ospiti appartenenti agli ordini: Insecta: Mantodea, Orthoptera, Embioptera, Hemiptera, Coleoptera, Neuroptera, Diptera, Lepidoptera; Arachnida: Araneae Dysderiidae, Lycosidae. Grazie all'intenso lavoro di ricerca del professor Giovanni Mineo, r…
Effect of dual biotic stress on plant volatile synomones used by egg parasitoids
2014
Studies on semiochemical communication have demonstrated that broad bean plant, Vicia faba, emits volatile synomones induced by feeding and oviposition activities of the southern green stink bug, Nezara viridula, which recruit the egg parasitoid Trissolcus basalis. However plants growing in agro-ecosystems can be attacked by several herbivore species that could affect both above and belowground plant tissues with possible consequences for parasitoid recruitment. For example, broad bean plants can also be attacked by the leaf weevil, Sitona lineatus, and simultaneous attacks by the southern green stink bug and the leaf weevil can occur in agro- ecosystems. The purpose of this work was to inv…
Electrophysiological and behavioural responses of the housefly to “sweet” volatiles of the flowers of Caralluma europaea (Guss.) N.E. Br.
2013
In sapromyiophilous plants, up to date, long range attraction of fly pollinators has been thoroughly investigated and attributed to ‘‘fetid’’ floral compounds, while the ‘‘sweet’’ floral scent fraction has not been spe- cifically investigated and its role has received little atten- tion. The aim of the present study was to verify if terpenoids, which are the main compounds of the floral bouquet of Caralluma europaea, play a role in the attrac- tion of its pollinator Musca domestica. Terpinolene, a- terpinene and linalool, described as the three main volatiles of the flowers of C. europaea, were evaluated in electro- physiological investigations and blends of these com- pounds as well as the…

Searching for the competitive ability of the alien seagrass Halophila stipulacea with the autochthonous species Cymodocea nodosa
2023
The tropical seagrass Halophila stipulacea (Forsskål) Ascherson, 1867 entered in the Mediterranean Sea through the Suez Canal more than 100 years ago. In coastal-marine ecosystems the spatial niche of H. stipulacea is often overlapped with that of native Mediterranean Sea seagrasses and therefore it might out-compete them. Aiming to better understand its invasiveness potential, we monitored a Southern Mediterranean shallow coastal-marine water habitat from August 2010 to August 2011, where H. stipulacea co-occurred with the native seagrass Cymodocea nodosa (Ucria) Ascherson, 1870. Besides, the year-round dynamics of H. stipulacea was also monitored in four periods. To test the hypothesis th…
