Figure 3. Effects of Beauveria bassiana and lambda-cyhalothrin insecticides on diversity (Shannon index), evenness (Hurlbert’s PIE)
and dominance (proportion of the most common species) before (A), 20 (B) and 40 (C) days after spraying (winter trial). Error bars
indicate 95% confidence limits over 1000 iterations (Gotelli and Colwell, 2001).
