This book (Malagasy silkworms. Ecological and sociological issues) reflects the achievements and scientific activities of the university cooperation project for the 'Management and sustainable enhancement of the endemic silkworm Borocera cajani in a forested area of the Antananarivo region" 'financed by the CIUF-CUD (University Development Cooperation in Belgium). The first section of the work deals with the biological and ecological aspects of silkworms in Madagascar-with emphasis on landibe (Borocera cajanus Vinson, 1863). The second section studies the ecological and botanical dimensions of the habitat of the species, namely, tapia formations (Uapaca bojeri Baill.), by focussing on the silvicultural and botanical aspects, the causes and indicators of its decline, etc. The third section provides information about the valorization of the silk industry and covers a variety of approaches including the compilation of an inventory of edible wild plant resources and their chemical characteristics. This section also looks at the role played by silk in the rural economy, and the knowledge and skills of local communities. The third section ends by taking a look at the socio-institutional context as well as interactions between the players involved in the industry. This work comprises 21 scientific contributions written by 33 authors ; some of them are in english and all the abstracts are written in french and in english. Several chapters have already been published elsewhere. This book is aimed at all those who are passionately interested in Malagasy society and biodiversity, and the potential value of this large island in the context of sustainable development.

Au début des années 1970, le renouveau de la production de la soie, une activité qui fut longtemps l'un des piliers de l'économie cévenole, déjoue tous les pronostics qui annonçaient sa disparition inéluctable en raison de la suite ininterrompue de crises techniques, économiques et sociales auxquelles elle a été confrontée depuis le milieu du XIXe siècle. Deux projets locaux de relance de cette activité voient en effet le jour quasi simultanément. Témoin direct de la relance séricicole, Françoise Clavairolle se livre à une ethnographie minutieuse, décrivant ses conditions et ses modalités techniques, analysant ses multiples enjeux, économiques, sociaux et symboliques ainsi que son échec final. à la lumière d'un cadre théorique emprunté à l'anthropologie des techniques et à la sociologie de l'innovation, elle propose une approche compréhensive de ce renouveau qui a tenté de concilier innovation et patrimonialisation.

Insects boast incredible diversity, and this book treats an important component of the western insect biota that has not been summarized before-moths and their plant relationships. There are about 8,000 named species of moths in our region, and although most are unnoticed by the public, many attract attention when their larvae create economic damage: eating holes in woolens, infesting stored foods, boring into apples, damaging crops and garden plants, or defoliating forests. In contrast to previous North American moth books, this volume discusses and illustrates about 25% of the species in every family, including the tiny species, making this the most comprehensive volume in its field. With this approach it provides access to microlepidoptera study for biologists as well as amateur collectors. About 2,500 species are described and illustrated, including virtually all moths of economic importance, summarizing their morphology, taxonomy, adult behavior, larval biology, and life cycles.
