Table 2 Toxicity of Bacillus thuringiensis isolate RM11 to diamondback moth, Plutella xylostella larvae, in comparison with positive control HD1

From: Characterization of indigenous Bacillus thuringiensis isolate RM11 toxic to the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae)

Isolate Regression equation χ2 LC50 (μg/ml) Confidence limits (95%) LC95 (μg/ml) Confidence limits (95%)
Lower limit Upper limit Lower limit Upper limit
RM11 Y = 4.4206 + 0.8843x 3.36 4.51 2.261 15.708 757.9 35.26 16,294.1
Positive control HD1 Y = 6.5494 + 1.3729x 4.07 0.07 0.052 0.102 1.17 0.69 2.60
  1. In negative control (78/11), there was no mortality even up to 1000 µg/ml and hence not included for comparison
