Egyptian Journal of Biological Pest Control

Table 1 Lethal concentration values of LC₅₀ and LC₉₀ (conidia/ml) of Metarhizium anisopliae and Beauveria bassiana for Bactrocera zonata fly at 72 h of treatments under laboratory conditions

Lethal concentration (conidia/ml)		χ²	χ² tabulated	P	Slope ± SE
LC₅₀	LC₉₀	χ²	χ² tabulated	P	Slope ± SE
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

LC₅₀—lethal concentration of 50% of the tested insect, χ²—Chi-square, P—probability level of 5%, SE—standard error
