Use entomopathogenic nematodes to control western corn rootworm / by Ganpati Jagdale

Efficacies of two biological control agents including entomopathogenic fungus (Metarhizium anisopliae) and insect-parasitic nematode (Heterorhabditis bacteriophora) against western corn rootworm, Diabrotica virgifera virgifera was compared with two insecticides including Tefluthrin (synthetic pyrethroid compound) and clothianidin (neonicotinoid compound).  According to Pilz et al (2009), insect-parasitic nematode,  H. bacteriophora was as effective as both insecticides in reducing population of the western corn rootworm.
