Radiosensitivity of two strains of the codling moth Cydia pomonella (Linnaeus) (Lepidoptera: Tortricidae) originating from different elevations in Armenia
Journal of Applied Entomology 134 (3), 227-233
Abstract: The purpose of this study was to analyse the radiosensitivity of codling moth Cydia pomonella (L.) strains from different elevations, 850 and 2000 m above the sea level. The level of sterility of parental males and inherited sterility of F1 males in the strain from the higher elevation at all radiation doses (80, 100 and 150 Gy) was significantly lower, than in the strain from the lower elevation. The frequency of chromosomal aberrations in the F1 generation in the strain from the higher elevation was significantly lower at 80 and 150 Gy than that in strain from the lower elevation. The average number of eupyrene sperm in the F1 males descended from irradiated males was higher in the strain from the higher elevation than in the strain from the lower elevation. Inheritance of the resistance/susceptible to ionizing radiation were examined by standard genetic cross-breeding analysis confirming the polygenic nature of the differences in radiosensitivity. The implications of these findings for the implementation of area-wide integrated pest management programmes that integrate the use of sterile insects are discussed.
