Halyomorpha halys

The Brown Marmorated Stink Bug has been detected in the UK on several occasions, mainly on imports from China, mainland Europe and North America  It serious and what are its possible implications to UK wildlife and our biosecurity. Initial reports indicated it is a serious pest on more than 100 plant genera, including Apple Peaches and ornamentals such as Acer as a whole genus.


Brown Marmorated Stink Bug is native to much of East  Asia. The adults will feed mainly on fruits where they suck out the juices, while the younger stages of the bug tend to feed on foliage and stems. There are more than 57 species of hitch-hiker stink bugs. Therefore, if established in the UK, it could cause serious economic damage to our food supply and devastate ornamentals.

It has spread to North America and was first detected in 1996 and in Europe in 2004. It now causes huge losses in crops like apple, pear, peach, apricot, cherry and kiwis. Perhaps more worrying is that it attacks soya and corn crops, causing damage estimated at é250,000,000. It has also been attacking greenhouse crops in Hungary and Switzerland. More worrying for consumers is the fact adults can invade warm houses in order to over-winter, where they leave a very unpleasant odour.

As of March 2022 this bug is not being treated as a quarantine pest as some think it is impossible due to its ability to hitch a ride not just on plant materials but also virtually any for of packaging. There  have been several sightings in the south of England and one in the city of Leicester. Scientists have not yet reported finding prof of breeding in the UK, unlike in Europe, where breeding is widespread.
