Some biologic characteristics of Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) reared in potato tubers was studied in laboratory at 25 ± 1ºC, relative humidity of 70 ± 10% and photophase of 14 hours. The male longevity it was 33.4 days and the female longevity it was 31.4 days, the survivor it was 100% until the 6º day for both sex, the total number of eggs per female of P. operculella it was 195, with viability of 46.3%, when these adults received a solution of honey at 10%.
