Abstract

The wings of Bombyx mori are known to become smaller when irradiated with γ-rays at the larval stage. This was considered to be a non-stochastic effect wherein the wing-size reduction curve, plotted vs. the irradiation dose, shows a threshold. Here we propose a new indicator for radiation sensitivity, named the wingless dose 50 (WLD50), which was obtained from the inflection point of wing-size data normalized by the body-size changes and plotted against the irradiation dose. This indicator was confirmed to serve as a tool to compare irradiation sensitivity among B. mori strains.
