Pathogenicity of Steinernematid Nematodes on the Sweet Potato Weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae) and Their Feasibility for Suppression of the Weevil Population

Pathogenicity of Steinernematid Nematodes on the Sweet Potato Weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae) and Their Feasibility for Suppression of the Weevil Population

We evaluated entomopathogenic nematodes (Steinernematidae) as potential biocontrol agents to suppress the wild population of the sweet potato weevil, Cylas formicarius (Fabricius) as part of its eradication program. The pathogenicity of Steinernema carpocapsae (‘All’ strain), S. feltiae, S. riobrave...

Zusammenfassung:We evaluated entomopathogenic nematodes (Steinernematidae) as potential biocontrol agents to suppress the wild population of the sweet potato weevil, Cylas formicarius (Fabricius) as part of its eradication program. The pathogenicity of Steinernema carpocapsae (‘All’ strain), S. feltiae, S. riobrave and S. glaseri (‘326’, ‘328’, ‘Mungyeong’ and ‘Dongrae’ strains) was checked against the sweet potato weevil under laboratory conditions. S. carpocapsae induced the highest mortality in both sexes of the adult sweet potato weevil (90%
