Pathogenicity of Entomopathogenic Nematode, Steinernema carpocapsae GSN1 Strain (Rhabditida: Steinernematidae) against Tebenna issikii (Lepidoptera: Choreutidae)
Abstract
Entomopathogenic nematode, Steinernema carpocapsae GSN1 strain was evaluated for the environmentally sound control of Tebenna issikii (Lepidoptera: Choreutidae) in the laboratory. The corrected mortality of Tebenna issikii larvae was 100% at the 40 infective juveniles (Ijs)/larva 3 days after treatment with S. carpocapsae GSN1 strain in Petri dish. LC₅₀ value of S. carpocapsae GSN1 strain against Tebenna issikii was 5.7 Ijs. The mean penetration numbers of Ijs of S. carpocapsae GSN1 strain at the 5, 10, 20, 40 and 80 Ijs/larva in a Tebenna issikii larva were 1.4, 1.4, 3.2, 5.6 and 11.9 Ijs/larva, respectively. However penetration rate of Ijs of S. carpocapsae GSN1 strain at 5 Ijs/larva was the highest among other nematode concentrations. Progeny of S. carpocapsae GSN1 strain in a Tebenna issikii larva was higher with increasing nematode concentration.
