An experimental transgenic Bt cotton cultivar "NuPEARL" was evaluated in the Mississippi Delta for efficacy against a multitude of lepidopteran pests. This cultivar appears to have higher Cry1Ac expression than normal Bt cotton cultivars. Correlations among efficacy and expression of Cry1Ac will be discussed
