Abstract
Determination of Optimal Temperature for Production of Quality Eri Silkworm Cocoon and Seed
Highlights
Bere Silk Production PLC is the largest commercial silk producer and processor in the country
Because of lack of specific research information on optimum temperature for egg laying and cocoon production at Arba Minch area, this study evaluated the effect of temperature ranges on egg and cocoon productions to fill the prevailing gap
The results of study showed that eri silkworm growth performance measured as cocoon weight, pupa weight and shell weight, egg number and hatchability were significantly (P
Summary
Bere Silk Production PLC is the largest commercial silk producer and processor in the country It purchases cocoons from smallholder farmers, while supplying them with silkworm seeds. The company works with both individual smallholder farmers and farmers’ groups to develop the local sericulture industry. It has been supplying the farmers with seeds of eri silkworms and castor beans, as well as deliver technical advisory services. 2324 °C optimum temperature and 75-80% relative humidity are required. Regardless of the location, profitable silkworm rearing requires suitable temperature, relative humidity, light intensity, soil type and low rainfall. Because of lack of specific research information on optimum temperature for egg laying and cocoon production at Arba Minch area, this study evaluated the effect of temperature ranges on egg and cocoon productions to fill the prevailing gap
