Some Effects of Gamma Irradiation on the Gypsy Moth, Porthetria dispar

Abstract
Pupae and larvae of the gypsy moth, Porthetria dispar (L.), were irradiated with a cobalt-60 gamma source. The effect of various dosages on pupal survival, adult longevity, mating success, egg numbers, egg viability, and F1 survival are reported. The irradiation of pupae more than 9 days old with 20,000 r resulted in very few crippling defects of the treated insects and reduced egg hatch to a low level.
