In the context of the German biosafety research programme, scientist Mechthild Schuppner is attempting to determine whether genetically modified Bt maize is harmful to domestic butterflies. At Aachen university, she is conducting feeding experiments with small tortoiseshell butterflies. Therefore, she has succeeded in establishing a breeding programme for the winged subjects of her study. Her experiments include temporarily supplying larvae with a special diet of pollen from Bt maize, in order to check if this has an impact on their development or may even kill them.

We have captured Mechthild Schuppner's research on film: you can watch the video under http://www.gmo-safety.eu/en/maize/ecosystem/734.docu.html. There you can also read an article that elucidates her work in more detail.

We would be pleased if you report about the topic.
