Competitive abilities of the entomopathogenic Nematodes steinernema feltiae and Heterorhabditis bacteriophora in the same host at different temperatures

The effectiveness of Turkish strains of the entomopathogenic nematodes Steinernema feltiae and Heterorhabditis bacteriophora on the last instar larvae of Tenebrio molitor were investigated. Mortality rates of T. molitor larvae caused by each nematode species alone (experiment I) were determined.
