Figures & Tables

Figure 1

Mean (±standard error) percent codling moth (CM) pupal mortality at 2 and 3 days post treatment in round 1. Treatments included Steinernema carpocapsae, Steinernema feltiae, and Heterorhabditis bacteriophora and a water only control with seven CM pupae per replication. Different letters above bars indicate statistical differences among treatments within each time posttreatment (SNK test, alpha = 0.05).

Figure 2

Mean (±standard error) percent Oriental fruit moth (OFM) pupal mortality at 2 and 3 days posttreatment in round 1. Treatments included Steinernema carpocapsae, Steinernema feltiae, and Heterorhabditis bacteriophora and a water only control with seven OFM pupae per replication. Different letters above bars indicate statistical differences among treatments within each time posttreatment (SNK test, alpha = 0.05).

Figure 3

Mean (±standard error) percent codling moth (CM) pupal mortality at 2 and 3 days posttreatment in round 2. Treatments included Steinernema carpocapsae, Steinernema riobrave, Steinernema glaseri, and Heterorhabditis indica and a water only control with seven CM pupae per replication. Different letters above bars indicate statistical differences among treatments within each time posttreatment (SNK test, alpha = 0.05).

Figure 4

Mean (±standard error) percent Oriental fruit moth (OFM) pupal mortality at 2 and 3 days posttreatment in round 2. Treatments included Steinernema carpocapsae, Steinernema riobrave, Steinernema glaseri, and Heterorhabditis indica and a water only control with seven OFM pupae per replication. Different letters above bars indicate statistical differences among treatments within each time posttreatment (SNK test, alpha = 0.05).
