Oil production: oil derived from genetically

modified oilseed rape contains a lower level

of erucic acid that for its toxicity is allowed

a maximum permissible limit of 5% in edible

fats

Animal feed

Production of margarine

supplemented with

methanol, methyl ether

plant (biodiesel) can be

used for the propulsion

of diesel engines

Pasta with Brassica

fruticulosa, tomato, pine

nuts, garlic and olive oil

Sausage and Brassica

fruticulosa

Herbicide tolerant: mainly to Glyphosate (GM HTCanola)

Pest resistance: GM plant modified with genecryIAb with insecticidal proprieties againstlepidopteran pests

Plutella xylostellaPieris brassicae

Gene flow: trasmission of pollen by wind and

insects can get to fertilize plants placed a Km to

distance

Persistence of GM trait: loss of seeds in the field

before and after harvest up to 10%. Much remains

viable for 5-10 years resulting in the birth of GM

plants in subsequent years

Impact to non-target insects: directly and

indirectly on adults and larvae (mainly

Lepidoptera)

Bioindicators of biodiversity

The preliminary results of this study highlight

the necessity to use as focal species to assess

the potential impact of GM Bt canola, for

monitoring protocols, some of the species

present in the area and who have flight

period overlap with the Bt canola pollen

production
