Biological control agents (BCAs), mainly entomopathogenic nematodes (EPNs) are a great alternative to chemical insecticides for managing spotted wing drosophila (Drosophila Suzuki). Until 2010, Michigan’s blueberry integrated pest management (IPM) program was a sustainable system that targeted the main blueberry pest complex (cranberry and cherry fruitworms, blueberry maggot and Japanese beetle). After the arrival of spotted wing drosophila (SWD), insecticide applications increased to more than 10 per season, and pest management expenses went from $75/acre to $456/acre in 2014 (MSU-AABI 2016). In response, the MSU Extension Blueberry IPM Program started on-farm trials to assess the performance of entomopathogenic nematodes (EPNs) and soil dwellers.

Growers can download this poster on more information about these trials, which was presented at the 2024 Great Lakes EXPO in Grand Rapids, Michigan, on Dec. 10-12, 2024.
