Figures & Tables

Figure 1:

Mean percentage survival (± SEM) of Rhagoletis pomonella pupae when exposed to various treatments in 30-ml soil cups for 7 days (short-term bioassay). Control = no nematodes, Sc-ALL = Steinernema carpocapsae ALL strain, Hb-VS = Heterorhabditis bacteriophora VS strain, Hi-HOM1 = Heterorhabditis indica HOM1 strain, Hmeg = Heterorhabditis megidis UK211 strain, Sf-SN = Steinernema feltiae SN strain, Sg-VS = Steinernema glaseri VS strain, Sr-355 = Steinernema riobrave 355 strain. Different letters above bars indicate statistical significance according to ANOVA and Tukey’s test (α = 0.05).

Figure 2:

Mean percentage survival (± SEM) of Rhagoletis pomonella pupae when exposed to various treatments in 30-ml soil cups for 30 days (long-term bioassay). Control=no nematodes, Sc-ALL = Steinernema carpocapsae ALL strain, Hb-VS = Heterorhabditis bacteriophora VS strain, Hi-HOM1 = Heterorhabditis indica HOM1 strain, Hmeg = Heterorhabditis megidis UK211 strain, Sf-SN = Steinernema feltiae SN strain, Sg-VS = Steinernema glaseri VS strain, Sr-355 = Steinernema riobrave 355 strain.
