Are all modern Canolas, transgenic canola containing Bt ? http://www.plantphysiol.org/cgi/reprint/112/1/115.pdf What about the relation between canola's Bt and Nosemas in bees? http://en.wikipedia.org/wiki/Diseases_of_the_honey_bee It has been reported that exposure to corn<http://en.wikipedia.org/wiki/Maize>pollen containing genes for *Bacillus thuringiensis<http://en.wikipedia.org/wiki/Bacillus_thuringiensis> * (Bt) production may weaken the bees' defense against *Nosema*[5]<http://en.wikipedia.org/wiki/Diseases_of_the_honey_bee#cite_note-sciam-4>. In this study, it is stated that in relation to feeding a group of bees with Bt corn <http://en.wikipedia.org/wiki/Bt_corn> pollen and a control group with non-Bt corn pollen, that: "in the first year the bee colonies happened to be infested with parasites (microsporidia). This infestation led to a reduction in the number of bees and subsequently to reduced broods in the Bt-fed colonies as well as in the colonies fed on Bt-toxin-free pollen. The trial was therefore discontinued at an early stage.This effect was significantly more marked in the Bt-fed colonies. (The significant differences indicate an interaction of toxin and pathogen on the epithelial cells of the honeybee intestine. The underlying mechanism which causes this effect is unknown.)" http://www.bioone.org/doi/abs/10.1603/0022-0493-94.6.1361?journalCode=ecen -- Juanse Barros J. APIZUR S.A.
