Rosengren, Anna, 2006: Samiska kvinnor och osynlig historia. En komparativ studie av svenskar och samer vid 1600-talstinget. (Saami Women and Invisible Histories. A Comparative Study of Swedes and Saamis in Court during the 17th Century.)The purpose of the paper is to gain new knowledge about Saami women in the 17th century using court protocols in the Luleå and Torneå Lappmarks, supplemented by secondary sources.Saami women did not write their own history, nor did Saami men. Information available about Saami is written by male representatives of the Swedish crown and church.

The study was performed in southwest of Colombia in close collaboration with the interna-tional centre of tropical agriculture, CIAT and supervised from the university of Valle, Uni-valle, Cali, Colombia and from the Department of Landscape Management and Horticultural Technology, SLU, Alnarp, Sweden. The main purpose of this thesis was to evaluate six different non-conventional insecticides and their ability to control whitefly Aleurotrachelus socialis in cassava Manihot esculenta. The aim was also to evaluate the most appropriate application technique for these products which were: Agronim, Biomel, Bioneem, EcoSwing, Coco soap + chilli and L´Ecomix. The products are mainly based on vegetable oil, soap and plant extract and cause primarily a physical contact effect which affirm that it is fundamental to obtain a high coverage of the underside of the leaves, where A. socialis is present.
