Fig. 2. lethal concentrations for 50% individuals (LC50) of P03, P05 and P14 Aedes rusticus populations to Cry4Aa, Cry4Ba, Cry11Aa toxins and commercial Bacillus thuringiensis subsp. israelensis ( Bti ). Untreated populations are indicated in white and treated populations in black. Error: 95% confidence intervals calculated with the probit statistical analysis. 1160, 2320 and 2320 larvae were sampled from P03, P05 and P14 populations, respectively. Approximate distance between the sites: P03-P05, 70 km, P03-P14, 58 km and P05-P14, 85 km. Asterisks mean p < 0.05. NS: not significant.
