Biological characteristics of some mutant mulberry silkworm (Bombyx mori L.) forms

Abstract

Based on the results obtained and the analysis made we could draw the following conclusions: the factors temperature and laser beams used reduced the biological traits of mulberry silkworm; the reduction of silkworm viability in result of temperature and laser beam treatments was race specific; gamma irradiation had a slight effect on the silkworm biological traits and no race differences were established; the use of ethyl methane sulphonate led to an increase in the main biological traits
