Radiation sterilization of the greenhouse white fly (Trialeurodes vaporarium Westw.; Homoptera: Aleurodidae). Part 1

Results are reported of studies on the sterilizing effect of ionizing radiation on puparia and imagoes of the greenhouse white fly. The irradiation was made by gamma rays (60Co) at rate of 12±5% rad/s. On the basis of the dose-mortality curve, the main parameters of the lethal radiation effect for puparia were determined (LD, regression coefficients). It was found that in the irradiated populations existed susceptible and resistant fractions and a higher radioresistance of the females as well. The radiation sickness of white flies, emerged from irradiated puparia, reduced their longevity according to the applied dose. The direct irradiation of the adult insects produced the same effect, but after using higher doses
