Trap crops enhance the control efficacy of Metarhizium brunneum against a soil-dwelling pest

Soil-dwelling insect pests may cause considerable damage to crops worldwide, and their belowground lifestyle makes them hard to control. Amongst the most promising control agents for subterranean pests are soilborne entomopathogenic fungi (EPF) such as Metarhizium brunneum. Albeit EPF can be highly pathogenic to their target pest species under laboratory conditions, their efcacy in the feld is often limited due to adverse environmental conditions. Here, we test for the first time if the efcacy of EPF can be improved when they are augmented with trap crops.
