Brown marmorated stink bug, Halyomorpha halys
Brown marmorated stink bugs are invasive sucking insects that cause serious economic damage to a wide range of fruit, grain and vegetable crops. Serious infestations of this polyphagous pest have resulted in 25-90% crop losses in apple, peach, sweetcorn, pepper, tomato, maize and soyabean crops within the last decade. Halyomorpha halys is multivoltine, producing up to 5 generations per year. Additionally, thresholds for the insect are extremely low (2 per row foot / 5 per 15 sweep nets) as its feeding behaviour causes ‘cat-facing’ or seed failure; ensuring crops are unmarketable. As such, monitor this destructive pest using Cross Vane Funnel or Delta traps with Halyomorpha halys aggregation pheromone lures as part of an integrated pest management programme.
