Halyomorpha halys now affecting apple orchards in Piedmont
The brown marmorated stink bug (Halyomorpha halys) is not the only harmful pentatomidae that can be found in orchards, so it is very important to be able to recognise the other species as well. Agrion technicians have therefore prepared the table below to make them easier to recognise.
H. halys compared to other bugs
In the Piedmont area, this insect has two generations a year and spends winter in sheltered environments such as houses, warehouses, etc. Due to this year’s mild weather, it managed to survive even in the fields.
Graziano Vittone, Agrion technical coordination manager, warns producers about the brown marmorated stink bug. “Now that the peach season is ending, you must monitor your apple orchards. Inspect the trees, especially the upper foliage, or shake them after placing a film underneath to count how many fall to the ground. These are both time-consuming operations, but they enable growers to assess the problem.”
“You must intervene as soon as you notice the insect on the outer trees as, if it colonises the orchard, it will be too late and most of the produce will be damaged.”
In all other cases, it must be stressed that bugs reach apple orchards from kiwi trees, peach orchards and cereal crops, so the edges must be constantly checked and protection barriers must be put in place.
