Abstract
The genetic effects of Apron 35 SD [Methyl D‐L‐N‐(2–6‐dimethyl phenyl)‐N‐(2'‐methoxyacetyl‐alaninate)], a new chemical fungicide produced by Ciba‐Geigy, on the male and female germinal cells of the silkworm Bombyx mori has been investigated. 50 μl of 50, 100, 200 and 400 ppm of the chemical in 0.75% NaCl were injected into five‐day‐old male and female pupae at the wingbud region. The resulting moths were mated to untreated moths of the opposite sex, and the female moths of both crosses were allowed to lay eggs. The results showed that when the males were treated, the chemical induced a significant amount of dominant lethals. The crosses involving the treated female produced a large percentage of unfertilized eggs. The percentage of dominant lethals and the unfertilized eggs obtained increased proportionately with the increase in the concentration of the fungicide. Thus Apron 35 SD is both mutagenic and antifertility agent in silkworm B. mori.
