Résumé partiel
The chinese citrus fly is one of the key pests in Bhutanese mandarin orchards that lays eggs in developing fruit that cause pre-mature fruit drop. In this study it is used as a "model subject" to explore the integration of technical, social and administrative domains of knowledge. The confinement of the study to control of the fly leads to the study addressing a broad set of issues that are linked through their relevance to control the pest. Citrus fly control and its consequent doubling of the mandarin harvest is relatively easily measured and could serve as an indicator for effectiveness of technology development, farmers’organisation, government services and policies.

Part 1 deals with the socio-economic aspects of the study, and deals with the link between technology, learning processes and organisation. Chapter 1 gives the socio-economic and historical background of the area of study. The area falls under Pemagatshel and Samdrup Jongkhar districts in Bhutan, it is mountainous and borders Assam (under India) in the south. The inhabitants are Sharchok-pa or eastern Bhutanese people with an Indo-Burmese origin, they speak a distinct language that is not written. The local religion is dominated by the Nyingma-pa sect of the Mahayana Buddhism that heavily draws upon Tibetan traditions. The "Dzongda" or District Administrator is the representative of the Royal Government of Bhutan in the "Dzong", the District Administrative centre. Forestry, livestock and agriculture sections represent the Ministry of Agriculture and carry out the developmental programmes in the district. Districts are divided in blocks headed by a kind of mayor, blocks consist of five to fifteen villages with village headmen.
