Figure 4. Effects of B. bassiana and lambda-cyhalothrin insecticides on diversity, evenness
and dominance (spring trial): Shannon index, Hurlbert’s PIE and proportion of the most
common species before (left) and 30 days after spraying (right). Brackets indicate 95%
confidence limits over 1000 iterations (Gotelli and Colwell, 2001).
