Figure 1:
Mortality of medium (Me) or large (La) Phyllophaga vetula larvae due to the separate or combined application of Metarhizium anisopliae (M1cog) at two doses (H = 1 × 108 or L = 1 × 106 spores/insect) and 250 IJs of Steinernema glaseri (Sg) or Steinernema carpocapsae (Sc). SE, standard error.

Figure 3:
(A and B) Mortality of large (La) or medium (Me) Phyllophaga vetula larvae due to the increase in the dose of Metarhizium anisopliae M1cog, H = 1 × 108 or L = 1 × 106 spores/insect, before the application of 250 IJs of Steinernema glaseri (Sg) or Steinernema carpocapsae (Sc).
