Table 1. Comparison of the toxicity of Cry4Ba and its mutant inclusions towards A. aegypti larvae.

Toxin inclusion	LC50† (µg ml−1)
Wild-type Cry4Ba	0.50 (0.36–0.71)
Cry4Ba-R203Q	0.59 (0.37–0.93)

^†LC₅₀ represents the toxin inclusion concentration that leads to 50% mortality after 24 h exposure to a serial dilution of each toxin inclusion. 95% confidence limits are indicated in parentheses.
