The International Sericultural Commission • Intergovernmental organization created in 1960 • All main silk producer States are members but not China • Headquarters in the city of Lyon in France • Purpose : promotion of development of sericulture ( technical support, contacts, data collection, quarterly journal : SERICOLOGIA,…).

Tropical sericulturaldevelopment : theoricalpossibilities • Most countries in the tropical belt or subtropical belt have a favourable climate in south-east Asia, Africa and America. • Raw silk has a hight economic value, and is capable of producing additional cash income to the numerous and poor rural populations.

Tropical sericulturaldevelopment : practicalnecessities • Agro-climatic conditions (maximum temperature for highperforming silkworm strainsrearing : 30°C). • Qualities of potentialrearers (oftenwomen) : attention to details, diligence, time. • Availability of specificrearingpremisesprotectedfrom the otheractivities of the farm.

Tropical sericulturaldevelopment : practicalnecessities • Sericulture is to be develo ped in areas: - far removed from consumer markets or ports, where no other major activities are profitables at the same season(s) like industrial crops, - where food products are consumed locally. • It is very hazardous to envisage sericulture as a mono-production.

Tropical sericulturaldevelopment : practicalnecessities • Existence of a handicraft tradition or a textile industry, this is a prohibitive factor. • Existence of a processing circuit, i.e. leading to a domestic market for raw silk . Source : ISC
A complexagro-industrialprocess: sericulture (1) • Mulberrycultivation (pedological and climatic conditions, appropriatevarieties, growing techniques). • Grainage and silkworm rearing ( search for appropriate cross breeds, grainage management, rearing technique). • Cocoon handling ( collection, stifling, storage) Source : ISC
A complexagro-industrialprocess: sericulture (2) • Reeling (human and material ressources required for manual, semi-automatic and automatic basins). • Silkconditioning (human and material ressources required to test and classifyrawsilks). • Treatment of silkwaste (carding, combingspunsilk or noilsilkyarns). Source : ISC
A complexagro-industrialprocess: silkprocessing Only for those who want to export raw silk : • very hight quality : minimum 3A grade. • Use of less sophisticated machines makes it possible to use lower-grade silks but requires plentiful and experienced labour-force. Source : ISC
A complexagro-industrialprocess: by-productsfrommulberry • Fibers (phloem of shoots) • Paper (bark) • Wood (hockey sticks, cricket bats, tennis rackets, bobins, toys, furniture,….) • Fodder (leaves for cattle, poultry,….) • Traditionalmedecine and traditionalhealthydiet (fromroot, stem, leaves, fruit) Source : ISC
A complexagro-industrialprocess: by-productsfrom silkworm • Pupae for human or animal feeding • Pupaeoil for soap, cosmetics, paints and varnishes • Silkmoth for medicinalwine (China) • Potential source of antibacterial peptides, antifungal fractions (larvae), lecithin, chitin, chitosan (pupae) • Use of silkworm as bio-reactor (by transgenesis) Source : ISC
SOME IMPERATIVES • Training • Research • Dissemination of techniques • Programming: countries with no sericultural tradition/ countries withsericultural traditions Source : ISC
International cooperation and information • Everyprecise and localisedproject must be the object of an appropriate and specificstudy. • This canbeachievedefficientlywith the support of different types of competenceswhichexist in various countries. • International cooperationis indispensable and especially for researchprojects. • ISC is best equiped to serve as focal points for multilateralcooperation.

Future of sericultural economy • Domination of China on raw silk exportations, the best solution is to develop finished products • Production of economic interest molécules by transgenesis • Derived products Source : ISC
