EFFECT OF CONTINUOUS LOW-LEVEL GAMMA-IRRADIATION ON SUCCESSIVE GENERATIONS OF DAHLBOMINUS FUSCIPENNIS (ZETT.) (HYMENOPTERA: EULOPHIDAE)
Keyword(s):
D. fuscipennis were reared under continuous gamma-radiation at 10, 5, and 2.5 r/hr. At 10 r/hr the population failed to reach the third generation. After two generations at 5 r/hr the population was reduced in numbers to 20% or less of the control population, hut managed to survive for the seven generations through which the experiments were continued. At 2.5 r/hr the numbers in the first five generations were reduced below those of the controls, but had completely recovered by the sixth generation.
