100% of homozygous larvae are killed by 0.1% methyl methanesulfonate.
Hemizygous male larvae are sensitive to methyl methanesulfonate (MMS). They show sensitivity to ultra violet (UV) light. Sensitivity to MMS is recessive at 0.075% MMS and shows a strong semidominant effect at 0.125% MMS. 23.9% of eggs laid by homozygous females develop into adults that eclose.
