摘要: Abstract The sterility of male G. p. palpalis irradiated in the pupal stage and as adults with gamma doses 4–12 krad given air was investigated. treatments did not reduce viability, mating effectiveness longevity. Fertility showed a dose-dependent reduction increasing dose. required to fertility 5% or less males treated −10 +5 day-old flies were about 6 12 respectively.
