Emergence (±SEM) of Trissolcus japonicus from egg masses placed at three locations in an apple orchard treated with thiamethoxam + λ-cyhalothrin. The number of replicates for each treatment is presented in parentheses. Values with an asterisk are significantly different (p < 0.05) from the untreated woodline value in that column.
