Cabbage damage and control efficacy in field trials. (A) Images of five leaf damage grades. (B to E) Damage grades and relative efficacies in different treatments against cabbage pest complex during trials 1 and 2 (HVB and WT, transgenic and wild-type B. bassiana formulations; EB, emamectin benzoate recommended for cabbage pest control; BC, blank control). One or two asterisks marked on the bars grouped on a given sampling occasion denote significant differences among the treatments at P levels of <0.05 or <0.01, respectively, in a Kruskal-Wallis test (for damage grades) or one-way ANOVA (for efficacies). (F) Postspray survival trends of fourth-instar P. rapae larvae in the field bioassays of HV8 and WT versus BC. (G and H) Symptoms of P. rapae larvae that died of HV8 and WT, respectively. Error bars indicate SEMs from four plots (B to E) or four replicates (F).
