A survey was carried out to study the distribution, composition and economic importance of silkworm diseases between 2015 and 2017 in some parts of Ethiopia. From the surveyed areas, diseased silkworms were observed and distinguished at their station. In addition, sample infected silkworm parts were taken and examined in Melkassa Agricultural Research Center (MARC). The result showed that flacherie, grasserie and muscardine diseases were observed as a consequence of pests’ contamination on mulberry and eri-silkworm race with different rates of incidence and severity levels. Very high infestation and damage levels were found from flacherie and grasserie diseases. Flacherie and grasserie, recorded from most of the surveyed area were the most widely distributed disease. Muscardine disease was observed as low level of intensity. However, pebrine disease was not detected in all surveyed areas.
