Radiation effects on adult emergence, longevity and fertility in the peach fruit fly, Bactrocera zonata (Saunders) at 3.5 Kr were studied in the laboratory condition to see the probabilities of sterile insect technique (SIT) for its fruitful application in field application. SIT is applied in integrated pest management program against tephritid fruit flies. In this paper, three parameters of irradiated B. zonata were evaluated for the possible use of SIT within the management of this pest. Pupae of B. zonata were irradiated at 3.5 Kr one day before emergence and corresponding control were kept as non-irradiated control group. A significant effect (F=5.12, df=1, P=0.04) on adult emergence on both male and female was observed with the irradiated group whereas some negative effects on longevity and fertility of the peach fruit fly were found. Mortality rate was higher in newly emerged adults. Maximum number of irradiated males were died in week 4 (Mean=5.00) following the week 3 (Mean=3.33) and week 5 (Mean=2.67). The female irradiated flies were died high in number in week 5 (Mean= 2.50). The average of longevity for the control groups was 90 days longer than the irradiated groups that took 56.16 days. The irradiated groups of B. zonata showed no fertility, i.e. no progeny where non-radiated control groups had positive response of fertility. The present study supports the possibility of B. zonata management/or eradication at radiation dose 3.5 Kr in SIT.
