Classical Biological Control of Soil Insects in Field Corn and Alfalfa 1998
Project Leaders: Elson Shields, Tony Testa
Assess the ability of established, long-term, entomopathogenic nematodes (H. bacteriophora Oswego) to effectively respond to herbivore invasions under three rotation cropping systems.
This study monitors the population changes of established nematode populations when the cropping system is changed from continuous corn to other typical rotated crops on dairy farms. During 1998 new populations of soil herbivores failed to colonize each of the treatments (rotated crops), resulting in a continuing decline of entomopathogenic nematode populations.
