Table 1 Lethal concentrations of B. thuringiensis and B. bassiana against second instar larvae of T. absoluta

Biopesticides	LC₅₀	95% confidence limits	LC₉₀	95% confidence limits	Slope
B. thuringiensis (mg/ml)	0.24	0.16–0.48	4.16	1.35–6.48	1.33 ± 0.34
B. bassiana (spore/ml)	1.8 × 10⁷	1.2 × 10⁷–9.5 × 10⁷	48.9 × 10⁷	10.9 × 10⁷–100.4 × 10⁷	0.48 ± 0.24

The larvae treated for only 24 h and the larval mortality were recorded and corrected with the control until pupation
