| Environmentally sound control of fall webworm, Hyphanria cunea (Drury) with entomopathogenic nematode, Sreinernema carpocapsae Pocheon strain was evaluated in the laboratory and pot. Pathogenicity of 5. carpocapsae Pocheon strain was different depending on larval stage, i.e., mortality of the 2nd instar and the $3~4th$ instar was $100%$ with >20 infective juveniles (Ijs)/larva in 3 days, but the 5th instar was $34%$ with (Ijs)/larva in 3 days. Pathogenicity of 5. carpocapsae Pocheon strain was higher with increasing nematode concentration. Mortality of Hyphanria cunea larva by 5. carpocapsae Pocheon strain was not significantly different (more than $70%$) between nematode concentration on treated trees (Malus alba and Platanus orientalis) and in pot. |
