| Abstract: | Summary The toxicities of 4 alkylating agents (EMS, MMS, DES and MNU) were compared using 5th instar males ofLocusta migratoria cinerascens. The substances in order of (decreasing) toxicity were: MMS, MNU, DES and EMS. Treatment of different species, strains, stages and sexes revealed that the toxicity of EMS is not invariant with respect to these factors. Acridids compared to most insects are extremely radiosensitive; this study shows that they are  mutagen-sensitive also. |
