Abstract

[automatically translated] Sicily is one of the Mediterranean regions with the greatest biodiversity of flora and fauna whose conservation, it will also depend on a careful plan for risk assessment of the introduction of genetically modified plants (PGM) on non-target organisms. To this end we were chosen two representative areas of different habitats Sicilian: SIC "Raffo Rosso, Monte Cuccio and Vallone Sagana (ITA020023) and SIC" Capo Gallo "(ITA020006). 5 habitats have been identified: Olive grove, Mixed forest, Ampelodesmeto, Mediterranean and coastal Mediterranean Macchia Macchia to evaluate the potential risk of introduction of PGM Bt. Most of the literature on the effects of PGM towards non-target refers to Bt corn, but it is perhaps the rape that in the Sicilian situation should be assessed with caution. Sicily is considered the center of differentiation of different Brassicaceae, with a large number of endemic species that are also used in traditional gastronomy. 16 species of Brassicae may hybridize with canola grown including Brassica carinata (Fig. 1) used as a fall-Winter rape culture. The investigations carried out concerned the Lepidoptera, day and night, excellent environmental indicators and potentially exposed to Bt toxins and Beetles Coccinellidae. They were recorded 33 species of diurnal moths. The ampelodesmeto is the habitat with the highest number of species (Tab. 1), followed by olive grove, scrubland and coastal vegetation. Some species were found only nell'ampelodesmeto (pontia edusa, Melanargia pherusa, endemic species Fig. 2, Neohipparchia statilinus and Melitaea athalia). It 'was also found the presence of the helice form of Colias crocea species (Fig. 3). The samplings were carried out throughout the year and this has allowed us to know the flight periods of several species of moths in Sicily that in most of cases it was much longer than reported in the literature. Comparing the flight periods and that of the flowering rapeseed is known that they overlap for more than 70% of the species of diurnal Lepidoptera and this represents a potential risk of exposure to Bt pollen. Similar data are also found in the case of maize flowering . The quantitative sampling of larvae of Pieris spp. It was carried out on 100 host plants during the course of the entire year. Despite the abundance of Brassicaceae, and the presence of numerous adults of Pieridis also on suckler plants flowers (Fig. 4), only a small number of larvae was found on host plants. This monitoring was also conducted near a corn field: there have been no non-target lepidopteran larvae (Pieris sp., And Vanessa cardui) on host plants to coincide with the flowering of the corn, although several adults (12 species) were flying on the sidelines. For monitoring nocturnal moths we have been used light traps the data is being processed. The sampling of the spider beetles was made with the screen by mowing and with the frapage technique. They were identified 13 species, some found only in the coastal scrub. and the presence of numerous adults of Pieridis also on suckler plants flowers (Fig. 4), only a small number of larvae was found on host plants.
