Abstract: | The nematode Steinernema carpocapsae (All) strain was significantly more effective against peachtree borer larvae (Synanthedon exitiosa Lepidoptera: Sesiidae]) than Steinernema riobrave (7-12) strain in field and laboratory experiments. Eighty-eight percent control of peachtree borer larvae was obtained with S. carpocapsae in the field trial when applied at 3 x 10(5) infective juveniles per tree, and 92% mortality was obtained in the lab assay using 50 infective juveniles per larva. |
