[en] The study deals with the effect of feeding irradiated dates as a whole diet on some biological parameters of the fig moth Ephestia cautella. Statistical analysis of the results indicated that the differences in the following parameters were insignificant when measured and compared with insects reared wholly either on irradiated or on unirradiated dry dates fruits: 1-Average number of iarvae and pupae produced out of 400 seeded eggs after 30 days of incubation. 2-Average percentage of adult survival and their sex-ratio. 3-Mating frequency (average number of spermatophores per female) of the survived adults. 4-Average number of eggs laid per female. 5-Average percentage of egg hatchability. 6-Mating frequency, average number of eggs per female and average percentage of egg hatchability of F1 progeny adults produced from insect parents reared on 100 diet of irradiated as well as on unirradiated dates. Therefor, it could be concluded that disinfestation of date fruits by such a range of doses (50-100) Krad of gamma radiation might not have any adverse effect on the fig moth.(5 tabs., 33 refs.)
