Impact of low dosages of Bs WDG (0.5 and 1 kg/ha) on immature mosquito density in standardized field tests. A: during rainy season; B: during dry season. Daily differences in immature densities were analysed using Mann-Whitney tests at a significance level of p < 0.017. Different letters (a, b) on bars indicate a significant difference at the specific sampling day.
