Brown marmorated stink bug (Halyomorpha halys) surveillance 2021 - PH04104

Brown marmorated stink bug (BMSB, Halyomorpha halys) is an invasive pest now established in many European countries, causing significant crop damage and urban nuisance impacts. The insect species is originally from Asia but its global range has expanded considerably within the last three decades Climate-based niche models indicate that conditions in some regions of the UK are suited to establishment, with areas of Greater London likely to support at least one generation per year based on historic (c. 1975) climate data. With predicted climate change, larger areas of South East and Eastern England may become colonised by 2050.

Halyomorpha halys has a very wide host range and can feed on many crop species in addition to exotic ornamental woody plants. Tree fruit crops such as apple, pear, and stone fruits are particularly susceptible and likely to be the crops at highest risk if the pest should establish in the UK. Following arrival in a new region, H. halys can spread rapidly and have agricultural impacts very soon after establishment. Continued surveillance for this pest will be particularly valuable in South East England, so that growers can be alerted to potential risks to crops, allowing localised monitoring and control measures to be implemented at an early stage.
1) What is the current distribution of the pest in urban areas (Greater London) and crop production sites in South East England?

2) Is the pest reproducing in our climate?
