Abstract The present study was undertaken to verify ancient data in the literature on ovipositional preference of the cuttlefish Sepia officinalis for the terrestrial plant Pistacia lentiscus (mastic tree). -Adult specimens of Sepia were placed in basins together with aerial parts not only of P. lentiscus, but also of Artemisia arborescens, Centaurea alba var. deusta, Quercus ilex and Laurus nobilis. The egg masses deposited on the plants were quantified on a daily basis during the 16 day observation period. By far the largest amounts of eggs were found attached to the stems and petioles of P. lentiscus (51.8%), but Q. ilex and A. arborescens also scored high as ovipositional host plants (23.1 and 20.2% respectively). L. nobilis and C. alba var. deusta ranked very low (3.6 and 1.3% respectively). Considering the extremely divergent shape of the three preferred oviposition substrates, which excludes affinity for a uniform type of plant, the possibility of chemical attraction cannot be ruled out.

This  study deals with the biomass estimation of the understory species of Pinus halepensis    forests in the Kassandra peninsula, Chalkidiki (North Greece). These  species are: Quercus    coccifera, Quercus ilex, Phillyrea media, Pistacia lentiscus, Arbutus  unedo, Erica arborea, Erica    manipuliflora, Smilax aspera, Cistus incanus, Cistus monspeliensis,  Fraxinus ornus. A sample of    30 shrubs per species was taken and the dry and fresh weights and the  moisture content of    every component of each species were measured, all of which were processed  for aboveground    biomass data. Then several regression equations were examined to determine  the key words.

Abstract The chemical variations of the essential oil from the aerial parts of Laurus nobilis L. (Lauraceae) have been studied. Plant material has been harvested at each phenological status (vegetative, before anthesis, full flowering and seed-bearing). The oils were obtained by hydrodistillation of the air-dried samples. Analysis by GC and GC-MS of the essential oils has allowed to identify 39 compounds. The main compounds were 1,8-cineole, trans-sabinene hydrate, α-terpinyl acetate, methyl eugenol, sabinene, eugenol and α-pinene.

Xylosandrus compactus (Eichhoff) (Col.: Curculionidae, Scolytinae) is an ambrosia beetle species native to subtropical Eastern Asia, with great concern due to its high invasive ability. This species has invaded 54 countries worldwide, including 4 European countries (Italy, France, Greece, and Spain); it was detected in Mallorca (Balearic Islands, Spain) in October 2019. In the present work, X. compactus is recorded for the first time in the Iberian Peninsula (Girona province, NE Spain); specimens were collected in Banyoles (August 2020, attacking twigs of Laurus nobilis and Liquidambar styraciflua) and Platja d’Aro (October 2020, attacking twigs of L. nobilis). Up-to-date information is presented about its geographical distribution, host plants, biology, symptoms, associate damages, and the possible origin of this species in Europe.

During winter months and early spring 2011, we observed symptoms of scattered twig mortality in two historical woody urban parks of Campania (Southern Italy), at Portici (Parco Gussone: 40°48’ N, 14°20’ E) and Naples (Parco di Capodimonte: 40°52’ N, 14°15’ E). The woods consist of mature holm oaks (Quercus ilex) with an understorey of evergreen Mediterranean shrubs, natural regeneration of oak and several ornamental species. The examined dry terminals of holm oak, collected in late March 2011, hosted adult females of an ambrosia beetle of the genus Xylosandrus Reitter. Here, we report the first European record of the black twig borer (BTB) Xylosandrus compactus (Eichhoff) reproducing on new host plants in Italy. Insect and twig sampling was conducted irregularly during spring and summer 2011. Infested twigs of different host plants were isolated in plastic tubes, new emerged or callow adults counted and sexed and other biological data recorded. Hundreds of specimens of BTB, (>700 females and 43 males) emerged from sampled twigs or were directly collected from reproductive galleries at both localities.

Xylosandrus compactus and Liparthrum colchicum are two Scolytinae recorded for the first time in Italy in 2011 and 2019, respectively. X. compactus is an “ambrosia beetle” causing damages to several plants typical of the Mediterranean maquis through its digging activity on twigs and branches of the host plants. L. colchicum is a “bark beetle”, monophagous on laurel shrubs and trees. During a survey performed in summer of 2020, in “Tenuta Salviati” located in the Migliarino Natural Park (Pisa, Tuscany), adults of X. compactus and L. colchicum were collected from the same branches and apical twigs of Laurus nobilis hedges. The study aimed at characterizing fungi isolated from the external surface of the two scolytids bodies, to evaluate similarities and even their role in fungal spreading in the environment.
