Drosophila suzukii: a revolution for soft fruits in Trentino, North of Italy

Drosophila suzukii infestation on soft fruits was reported for the first time in Trentino, North of Italy, in 2009. This was the first record of this pest in Italy and Europe. Two years after, the spotted wing drosophila reached an extraordinary development of population, causing serious damages on soft fruits and cherries. An important infestation was also observed for the forst time on wine grape. Conventional insecticides, even if applied many times, were ineffective in reducing fruits damage, due to the very high pressure
of
the
pest.
 Interesting
results
were
obtained
with
alternative
control
methods
(anti‐insect
 nets,
mass
trapping,
attract
and
kill,
etc.).
 A
multi‐method
approach
seems
to
be
the
best
to manage D.suzukii infestations in a sustainable way in Trentino.
