Drosophila suzukii on stone fruit in the Lower Elbe region in 2016

In 2016 spotted-wing drosophila (Drosophila suzukii) developed economically relevant infestations
on cherries and plums in the Lower Elbe region in a similar manner as 2015. In both years
the fi rst two generations of D. suzukii on earlymaturing cherry cultivars were inconspicuous
whereas strong third and fourth generations developed on the main varieties Kordia and Regina,
opening up possibilities to determine precise dates of insecticide measures or fruit
picking. Incipient oviposition on Kordia and Regina was predictable a few days in advance. On
various plum cultivars the severity of D. suzukii infestations correlated with fruit maturity and a
variety-specifi c skin toughness. An early harvest in combination with a rapid cooling and a subsequent
maturation in storage could become important in controlling spotted-wing drosophila
on plums.
