Fig. 2.

Effect of augmenting the numbers of Steinernema diaprepesi(Sd), S. riobrave (Sr) or Heterorhabditis zealandica (Hz) in raw soil, followed by augmentation of S. diaprepesi 7 d later on numbers of entomopathogenic nematodes recovered from Baermann funnels. Error bars are standard errors of means. Bars with the same letter do not differ from each other according to Tukey's Honestly Significant Difference Test (P ≤ 0.05). White letters represent differences between numbers of S. diaprepesi and black letters represent differences between total numbers of EPN.
