Community Structure of Ammonia-Oxidizing Archaea and Ammonia-Oxidizing Bacteria in Soil Treated with the Insecticide Imidacloprid

Figure 6

The diversity indices for ammonia-oxidizing bacteria (AOB) in soil treated with imidacloprid (C: control; FR: 1 mg/kg soil; : 10 mg/kg soil). The data presented are the means and standard deviations of three replicates. Different letters (within each index) indicate significant differences (, LSD test), considering the effects of the pesticide dosage and time.
