No. significant difference was observed between the moisture regain of the wild silk fibers after degumming. However, there were significant differences in weight loss and moisture regain between cocoon shells as well as shell layers. E. bauhiniae had the lowest weight loss and moisture regain of 23.19 and 5.64%, respectively while G. postica had the highest weight loss and moisture regain, 56.84 and 9.05%, respectively. The SEM micrographs also showed the presence of remnant sericin gum on the fibers surface. In both A. panda and E. bauhiniae, the outer shell layers had the lowest moisture regain and highest weight loss while the inner layer of E. bauhiniae and middle layer of A. panda lost the least weight. The physical structure and chemical composition ofthe cocoon shells and fibers contribute towards the variation in the moisture regain and weight loss and these features may have commercial implications due to their direct effect on the resulting fabric

Kabaru, JM, Yenesew' A.  2003.  Plant derived larvicides as a tool to manage malaria in Kenya. AbstractPlant derived larvicides as a tool to manage malaria in Kenya

Malaria remains a serious parasitic disease killing over one million people annually. One of the strategies to manage the malaria problem is to control the population of mosquito at larval or adult stages of their life cycle. However with. the appearance of insect resistance to conventional insecticides together with the growing environmental concern on the use of many synthetic insecticides, in particular halogenated compounds such as DDT, the search for effective and environmentally friendly insecticidal agents is intensifying. In this effort some East African plant extracts and pure compounds have been tested for larvicidal activities (Muwangi and Mukiama, 1988; Mwangi and Rembold, 1988; Gikonyo et aI., 1998).

In laboratory tests conducted Oil adult locusts, the toxicity of crude 80% methanol extracts of M. volkensii fruit increased by more than 20-fold when the post-treatment temperature was raised from 1S"C to 40"C. This temperature-dependent toxicity was observed in insects treated either topically or via injection. This phenomenon could partly explain the wide variability in efficacy of M. volkensii fruit extracts reported by different investigators.
