  1. Notes: The different suspensions/solutions were all prepared at the same time but the larvae were only added to the treatments at 5-day intervals. Time zero: larvae added to freshly prepared suspensions/solutions. Different capital letters show statistical differences within each treatment over time (columns) at the 5% level using Duncan’s post hoc test. Different lower case letters show statistical differences between treatments for the same time point (lines) at the 5% level
  2. Abbreviations: F, Metarhizium anisopliae conidial suspension (1 × 109 conidia ml-1); N, neem oil 0.01%
