Relationship between two natural enemies of brown marmorated stink bug pest


A new CABI-led study has examined the relationship between two closely-related natural enemies of the brown marmorated stink bug in respect of how they interact when trying to attack the fruit and nut pest's egg masses.

The brown marmorated stink bug is a global pest which in 2016 caused $60m worth of damage to Georgia's hazelnut (a third of its crop) and in 2010, $37m worth of apples were destroyed in parts of the U.S..

Dr. Tim Haye, an expert on the brown marmorated stink bug (Halyomorpha halys) based at CABI's center in Switzerland, teamed up with researchers from the MARA-CABI Joint Laboratory for Bio-safety and Agriculture and Agri-Food Canada, to understand how competition between two scelionid parasitoids on the stink bug's eggs may provide insight into how they may coexist to fight the devastating crop pest.
