Abstract

The radiosensitivity in larval instars of tasar silkworm, Antheraea proylei (Lepidoptera) was studied by analyzing larval growth,
frequency of larval mortalities, moulting and larval durations. The growth of larvae was inversely proportional to dose of gamma
ray treated. The larval lethalities expressed in LD50 values were found to be 60 Gy, 115 Gy, 160 Gy, 210 Gy and 265 Gy in Ist, IInd,
IIIrd, IVth and Vth instars respectively. As dose increases the larval durations were also increased in tolerable doses
