Figure 3 in The lure of hidden death: development of an attract-and-kill strategy against Agriotes obscurus (Coleoptera: Elateridae) combining semiochemicals and entomopathogenic nematodes

Figure 3. Mean number of holes in the potato food source after infection according to nematode populations across time ((S. carpocapsae e-nema: χ2 = 73.62, p <0.001; S. feltiae AM25: χ2 = 5.03, p = 0.02, respectively). Light bars correspond to the treatments without potato extract, and the dark bars correspond to the treatments with addition of potato extract. Error bars represent the standard error of the mean.
