Abstract
After an aerial application, the possible persistence of Bacillus thuringensis subsp. kurstaki strain HD1 (Btk-HD1) in the soil of an oak forest near Florence (Italy), was assessed by means of morphotyping followed by a high throughput staining methodology and PCR analysis. The results show that although the numbers were relatively high on the phylloplane 24h after the insecticidal treatment, individuals belonging to the subsp. kurstaki were never detected among the members of the resident edaphic community of Bacillus thuringiensis.
