Potential impact of genetically modified Lepidoptera-resistant Brassica napus in biodiversity hotspots: Sicily as a theoretical model

摘要: The general increase of the cultivation and trade Bt transgenic plants resistant to Lepidoptera pests raises concerns regarding conservation animal plant biodiversity. Demand for biofuels has increased importation oilseed rape (Brassica napus L.), including lines. In environmental risk assessments (ERAs) its potential future as well food feed uses, impact on wild Brassicaeae relatives non-target should be assessed. Here we consider exposure butterflies results possible or naturalization spilled seed in Sicily (Italy). Diurnal Lepidoptera, which are pollinators, can exposed directly insecticidal proteins larvae (mainly Pieridae) through host pollen that deposit other plants. Adults via nectar. flight periods were recorded, they found overlap about 90% flowering period B. majority species. addition, a high hybridise with endemic taxa belonging oleracea group. This could lead an if introgression gene into population happens. A rank is given. We conclude that, assessments, attention paid plant-insect interaction especially biodiversity hotspot such Sicily.
