NALDC Record Details:
Adult emergence and sterility of Indianmeal moths (Lepidoptera: Pyralidae) irradiated as pupae in dried fruits and nuts
Download [PDF File]
Raisins, almonds, and walnuts infested with pupae of the Indianmeal moth, Plodia interpunctella (Hiibner), were treated with gamma radiation (14.4-92.1 krad). Effects of radiation on adult emergence and reproduction were similar in all commodities. Adult emergence was reduced or eliminated at the two highest doses;adults that did emerge were deformed and unable to mate successfully. Females from pupae irradiated with 26.9- 31.9 krad were completely sterile, whereas this dose only partially sterilized males. F, progeny of irradiated parents showed a high degree of sterility; female progeny were lessaffected than males. Presence of partially sterile males after irradiation with 26.9-31.9 krad does not reduce the potential of this dose for eliminating infestations in dried fruits and nuts because irradiated males are unlikely to mate with untreated unmated females within irradiated products.
