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. -

I further more cede copyright of the thesis in favour of the University of the Free State.” ________________________________ Ismari van der Merwe 2 February 2015 ii The establishment of a sustainable wild silk industry in Africa could pave the way for similar Africa-unique projects to capture the true spirit of the continent. That spirit that determines her worth and echoes in her truths: “Every morning in Africa, a gazelle wakes up. It knows it must run faster than the fastest lion or it will be killed. Every morning a lion wakes up. It knows it must outrun the slowest gazelle or it will starve to death. It doesn’t matter whether you are a lion or a gazelle… when the sun comes up, you’d better be running.” (Author: Unknown) iii Acknowledgements Research is never the work of one person alone. There are always a lot of people that in their own way, however small, helped to make a project like this possible. -

This news- issue of The Tachinid Times. This is the largest issue of the letter accepts submissions on all aspects of tachinid biology newsletter since it began in 1988, so there still seems to be and systematics, but please keep in mind that this is not a a place between peer-reviewed journals and Internet blogs peer-reviewed journal and is mainly intended for shorter for a medium of this sort. This year’s issue has a diverse news items that are of special interest to persons involved assortment of articles, a few announcements, a listing of in tachinid research. Student submissions are particularly recent literature, and a mailing list of subscribers. The welcome, especially abstracts of theses and accounts of Announcements section is more sizable this year than usual studies in progress or about to begin. I encourage authors and I would like to encourage readers to contribute to this to illustrate their articles with colour images, since these section in the future. This year it reproduces the abstracts add to the visual appeal of the newsletter and are easily of two recent theses (one a Ph.D. and the other a M.Sc.), incorporated into the final PDF document. -

Ten animals died on the farm over the previous 5 months. Magrecia Hausiku1 Erick Kandiwa1 Rumenotomies were successfully performed on three affected animals. The authors were of Pricilla Mbiri1 the opinion that the affected animals ingested the cocoons around the time of weaning, which Erdwin N.
