From: Virulence effect of Metarhizium anisopliae (Met.) and Beauveria bassiana (Bals.) fungi against the peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae)

Lethal concentration (conidia/ml) χ2 χ2 tabulated P Slope ± SE
LC50 LC90
M. anisopliae
 9.5 × 106 9.9 × 107 0.79 6.0 0.69 0.59 ± 0.244
B. bassiana
 5.1 × 107 1.9 × 109 0.69 6.0 0.71 0.82 ± 0.50
  1. LC50—lethal concentration of 50% of the tested insect, χ2—Chi-square, P—probability level of 5%, SE—standard error
