Abstract	The effect of Bt-cry1Ia1 (cryV now designated cry1Ia1 under revised nomenclature) of potato transgenic plants on the two species of potato tuber moth, Phthorimaea operculella (Zeller) and Symmetrischema tangolias (Gyen), was tested in Peru. Detached leaf bioassays were done using 10 neonate larvae per replication on each transgenic line of bred potato varieties Atlantic and Spunta. Mortality in Atlantic transgenic plants was lower for P. operculella, ranging from 18 to 34%, than for S. tangolias ranging from 40 to 94%. All transformed Spunta lines tested showed high levels of mortality in both species, with mortality ranging between 80 and 98%. The Bt-cry1Ia1 gene offers another source of resistance that can be pyramided for effectiveness toward the development of durable resistance to PTM and other insect pests.
