Fig. 5. lethal concentrations for 50% individuals (LC50) of P16, P20 and P52 Aedes sticticus populations to Cry4Aa, Cry4Ba, Cry11Aa toxins and commercial Bacillus thuringiensis subsp. israelensis ( Bti ). Error: 95% confidence intervals calculated with the probit statistical analysis. 1060, 1120 and 2280 larvae were sampled from P16, P20 and P52 populations, respectively. Approximate distance between the sites: P16-P20, 45 km, P16-P52, 58 km and P20-P52, 14 km. Asterisks mean p < 0.05. NS: not significant.
