Impact of insecticides on physical properties of mosquito bednets
Mutasim A Ahmed and Yassir A Eltahir
The purpose of this study is to apply insecticides to different types of fabrics used for production of mosquito nets, and to investigate the effect of treatment on fabric physical properties. Cotton, nylon and polyester bednets were treated with deltamethrin insecticide according to the recommended dosages. The mortality percentages of mosquitoes were evaluated using WHO cone test method in the insectry of the Blue Nile National Institute for Communicable Diseases, University of Gezira. The important physical properties of bednets were tested before and after treatment using different instruments and apparatus. The study proved that deltamethrin insecticide is more effective for nylon and polyester than for cotton bednets. The tearing strength and the tensile strength decrease, while elongation increases.
Statistical Package for Social Sciences (SPSS) was used for analysis. From the findings it can be said that treatment with insecticide affect the tensile strength of all types of bednets, tearing strength on cotton and elongation on polyester. From this study, deltamethrin insecticide is preferable to be used for nylon and polyester bednets.
