The Brown Marmorated Stink Bug is here, ‘kicking up a stink’ in the UK, as predicted by PCN!

In PCN 113, we asked ‘is the brown marmorated stink bug our next invasive pest?’

We can now answer this with a tentative “yes” thanks to the eagle-eyed observation of Melvin Knapp, Killgerm’s Technical Manager (South). Melvin spotted an individual Brown Marmorated Stink Bug (BMSB) Halyomorpha halys, inside an external rodent bait box, at a site in Hampshire this November.

“I recognised the Brown Marmorated Stink Bug, having been alerted to it from reading Pest Control News, then sent it to Killgerm’s entomologist for confirmation. I found it due to awareness, yet I expect others will have seen it and discounted it as the similar ‘mottled shield bug’ Rhaphigaster nebulosa or other shield bugs.” recounted Melvin. “I know it is an agricultural pest in other parts of the world but in the UK its main significance will be as an overwintering nuisance much like harlequin ladybirds and cluster flies,” explained Melvin.

Interestingly, the BMSB has been ‘flying under the radar’ for a little while in the UK. It turns out that there have been six previous finds of the BMSB in the UK known to Plant Health Controls. Four were in association with imported goods, one report on scaffolding outside an office and one record from passenger luggage. Findings were reported in 2010, 2013, 2014 (2), 2017 and now one in the public health pest control sector in 2018. It is not known whether this 2018 finding indicates an established population rather than isolated imports but it certainly raises the profile of yet another invasive pest species.
