چکیده

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.

A novel approach to biological control with entomopathogenic nematodes: Prophylactic control of the peachtree borer, Synanthedon exitiosa

Generally, microbial control agents such as entomopathogenic nematodes are applied in a curative manner for achieving pest suppression; prophylactic applications are rare. In this study, we determined the ability of two Steinernema carpocapsae strains (All and Hybrid) to prophylactically protect peach trees from damage caused by the peachtree borer, Synanthedon exitiosa, which is a major pest o...

Characterization of biocontrol traits in the entomopathogenic nematode Heterorhabditis georgiana (Kesha strain), and phylogenetic analysis of the nematode’s symbiotic bacteria

Our objective was to estimate the biocontrol potential of the recently discovered entomopathogenic nematode species Heterorhabditis georgiana (Kesha strain). Additionally, we conducted a phylogenetic characterization of the nematode’s symbiotic bacterium. In laboratory experiments, we compared H. georgiana to other entomopathogenic nematodes for virulence, environmental tolerance (to heat, desi...
