Dominant lethals induced by Dithane M-45 in silkworm Bombyx mori.
Dithane M-45, a ethylenebis(dithiocarbamate) fungicide widely used in agriculture, including moriculture and sericulture, was tested for its efficacy in inducing dominant lethals in Bombyx mori. A polyvotine race of Pure Mysore was used for the studies and the topical application method was employed. After treatment with sublethal concentrations of 5, 10, and 20 g/50 larvae, the results have revealed that all of the concentrations could induce significant dominant lethals in a dose-dependent manner compared to controls. The results are discussed in the light of precautionary measures in the use of Dithane M-45 in the sericulture industry.
