Abstract

The development of Bt corn expressing the insecticidal Cry1Ab protein from Bacillus thuringiensis (Bt) represents a novel approach for controlling potentially destructive populations of Asiatic corn borer (ACB) Ostrinia furnacalis. An important prerequisite to commercial development of Bt corn is a monitoring scheme for detecting the early evolution of insect resistance to Bt corn. This, in turn, requires the estimation of baseline susceptibility of ACB populations to Cry1Ab, which can be compared with future estimates of ACB susceptibility. These baseline susceptibility estimates also can be used as the basis for selecting a diagnostic dose for resistance monitoring , which is less labor intensive than the usual quantal response bioassays.
