Figure 1
Mean (% + SE) mortality of Melanotus communis larvae when treated with Beauveria bassiana (GHA strain), Cordyceps javanica (WF-GA17 strain), Steinernema carpocapsae (strain All), S. feltiae (SN strain), S. riobrave (strain 355), Heterorhabditis bacteriophora (VS strain), and H. indica (Hom1 strain) in a laboratory small cup bioassay. Treatment means with the same letter are not significantly different (P > 0.05, Tukey’s HSD test). HSD, honestly significant difference; SE, standard error of the mean.
Figure 2
Mean (% + SE) mortality of small and large Melanotus communis larvae when treated with Beauveria bassiana (GHA strain), Cordyceps javanica (WF-GA17 strain), Steinernema carpocapsae (strain All), S. feltiae (SN strain), S. riobrave (strain 355), Heterorhabditis bacteriophora (VS strain), and H. indica (Hom1 strain) in a laboratory small cup bioassay. Different letters above the bars indicate statistical significance (P < 0.05). SE, standard error of the mean.

Frequency distribution of wireworm weights tested in both trials. Shaded columns denote range of wireworm weights in which mortality was observed (0.04 g to 0.07 g).
