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.

(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).
