Diabrotica virgifera virgifera

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.

Control of the western corn rootworm with Heterorhabditis bacteriophora by Ganpati Jagdale

It has been demonstrated that that application of an entomopathogenic nematode Heterorhabditis bacteriophora can reduce the population of the western corn rootworm Diabrotica virgifera virgifera in the field and thus reducing the damage caused by this insect pest to corn roots and preventing subsequent lodging of plants (Stefan et al., 2010).

Use insect parasitic nematodes to manage western corn rootworms (Diabrotica virgifera virgifera) by Ganpati Jagdale

The western corn rootworm (Diabrotica virgifera virgifera) is a very serious pest of corn in the North America and Europe. Larvae of this insect exclusively feed on maize roots, often causing plant lodging whereas adults may reduce yields through silk feeding and interfering maize pollination.
