Abstract

The survival of Asian corn borer (ACB) exposed to Cry1Ab was initially estimated in Asian corn borer, Ostrinia furnacalis (Guenѐe), populations from 44 and 28 isofemale lines collected in Bgy. Alicaocao, Cauayan, Isabela (ACC) and Bgy. Reyes, Banga, South Cotabato (RBSC), respectively. Bioassays wree carried out using F2 neonates, which were individually transferred to plastic cups with Bt-corn leaf disc. A control group for each isofemale line was exposed to leaf discs from the same corn hybrid. Larvae were allowed to feed on the corn leaf disc for 24th to 48th. Larval feeding on the corn leaf was confirmed first before the surviving larvae were transformed to a new plastic cup with artificial diet. Results from 5 ACC isofemale lines revealed a mean larval survival and adult emergence rates of 0.13% and 0.07 % respectively. Meanwhile, data gathering for the RBSC isofemale lines is still on going to date.
