| Pathogenicity of the entomopathogenic nematodes Steinernema carpocapsae (Anannur strain)(Rhabditida: Steinernematidae), Heterorhabditis bacteriophora (Tur H|), H bacteriophora (Tur-H2)(Rhabditida: Heterorhabditidae) was tested against the cereal insect pest, Eurygaster maura (Hemiptera Scutelleridae). The cup assay was used to assess nematode pathogenicity in single dose and dose mortality bioassays. The singlc-dose assay showed that all three species caused significant host imo, tality, Neimatode-induced mortality increased as the exposure time increased from 72 to l44 h. The mortality induced by the nematodes S. carpocapsae, Tur-H l and Tur-H2, were 55%, 69% and 95% respectively. In single-dose exposures, the Tur-H2 strain of H. bacteriophora was the most pathogenic among thc three nematodes tested. LC values of the nematodes varied from 8 to 62. These results indicate that … |
