Biodiversa-Project Description-Final Version-110213
1.A. Detailed description of the research area and research plan Context of the proposal Biological invasions (bioinvasions) are defined as the successful establishment and spread of species outside their native range. They act as a major driver of global changes in species distribution. Diverse organisms and ecosystems may be involved, and although not all invasions have a negative impact, the ecological consequences often include the loss of native biological diversity and changes in community structure and ecosystem activity. There may also be additional negative effects on agriculture, forests, fisheries, and human health. National governments, intergovernmental structures like the European Commission and international organizations such as EPPO, CABI and IUCN have therefore mobilized to (i) introduce international laws on invasive species, (ii) organize international networks of scientists and stakeholders to study bioinvasions, and (iii) formalize the cooperation between national environmental or agricultural protection agencies (e.g. the French Agence Nationale de Sécurité Sanitaire, ANSES). Several billion euros are spent annually to address the problems caused by bioinvasions and the scientific community has focused on predicting and controlling future invasions by understanding how they occur. A peer-reviewed journal entitled "Biological Invasions” has been published since 1999. Ecologists have long drawn attention to the negative ecological effects of invasive species, whereas the evolutionary aspects of bioinvasions have received comparatively little attention. This reflects the fact that: i) invasive populations were thought to experience significant bottlenecks during their introduction to new environments and thus possess a limited potential to evolve; and ii) evolution was considered too slow to play a significant role given the relatively short timescale of the invasion process. -

The North Rift of Kenya Is a marginalized region where natural resources are under-utilized due to lack of technologies, market access and transportation. The Cabesi Project (from Camels, Bees and Silk) started in 2004 under lcipe's Commercial Insect Program. The camel program offered courses in camel husbandry and - health, and trainings for using camels for transportation. And in connection with ASAL Cabesi was able to increase the camel population by 30 animals. Cabesi provides since 2008 the complete infrastructure from beekeeping to production and sales of various bee-products. The system includes six honey collection centers in Pokot Central, West Pokot, North Pokot and Turkana Districts, and one Market Place in Kapenguria, where final processing, packaging and marketing are done. -

E-mail: [email protected] Received on December 3, 2010; accepted on December 8, 2011. Borocera cajani or “Landibe” (vernacular name) is the wild silk moth that is currently used to produce silk textiles in Madagascar. This species is endemic to Madagascar, and is distributed throughout the island, colonizing the Uapaca bojeri or “Tapia” forest of the central highlands. The forest provides food in the form of plants for B. cajani, including U. bojeri leaves. The species secretes silk at the onset of pupation and for making cocoons. Borocera cajani and its natural habitat are threatened by human destruction, such as bush fires, firewood collection, charcoal production, and the over-harvesting of their cocoons. -

Nutritional Opportunities of Edible Insects in Madagascar
Tropentag, September 9-11, 2020, virtual conference “Food and nutrition security and its resilience to global crises” Nutritional Opportunities of Edible Insects in Madagascar, Case of Borocera cajani and Bombyx mori Chrysalis Christian Tolojanahary Ratompoarison, Felamboahangy Rasorahona, Jean Rasoarahona University of Antananarivo, Department of Food Science and Technology, Madagascar Abstract In Madagascar, food consumption is marked by the predominance of cereals (rice and corn) and roots and tubers (cassava) and the low diversity of the diet. Food population intake is nutrient-poor. Several recent literatures show that insect consumption is common in rural areas. The lack of data on the nutritional composition of insects minimises the attention that nutrition stakeholders may pay to insects and constitutes a brake on the development of its consumption. In the present study, the nutritional potential of the chrysalis of two edible insects, Borocera cajani and Bombyx mori: the most locally used as food was determined and evaluated for the first time. B. cajani and B. mori contain 63.98 and 54.37 % crude protein, 29.84 and 35.78 % fat, 4.10 and 5.67 % ash, and 2.06 and 4.36 % carbohydrate, respectively. The essential amino acid (EAA) content shows that the amino acid scores of both insects exceeded the recommendation given by FAO/WHO/UNU (score >100). Amino acid profile shows that polyunsaturated fatty acid (PUFA) was the most predominant fatty acid found in both insects, followed by saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA). Mineral content was generally higher than that of conventional meat types. Both species fulfiled the recommended daily allowance (> 100 %) for Zn and Cu. -
