Corrected mortality of 28 isolates against adult T. tabaci 4 days post treatment in the laboratory.
Data are expressed as means ± SEM based on 3 replications, each consisting of 20 adults. All strains were tested at 1×107 conidia mL−1.

Corrected mortality of adult F. occidentalis and N. barkeri over 10 days following inoculation with 1×107 conidia mL1 of B. bassiana strain SZ-26.
Figure 3.
Corrected mortality of F. occidentalis and N. barkeri over 10 days following inoculation as first instars with 1×107 conidia mL1 of B. bassiana strain SZ-26.
After 10 days, surviving F. occidentalis had reached the pupal stage and surviving N. barkeri had reached the adult stage.
