Abstract

Globalisation and the export- import activities of foods contribute the expansion of invasive species in the world (Tait. et al., 2021). One of these species is the spotted wing drosophila (SWD) (Drosophila suzukii, Matsumara), which is a major threat to berries. Since it has a wide range of host plants and since it is an insect with several generations and a large population, it can cause enormous damage to berries (Wiman et al., 2016, Tait et al., 2021). Our experience shows that in Hungary it causes the most damage to blackberries, but it is also an increasingly common pest in our vineyards. Successful integrated pest management (IPM) can only be implemented by understanding the insect's biological cycle and ecological requirements. It is of paramount importance to strengthen the plants' defence system, avoiding diseases that give the green light to various pest organisms. By spraying salicylic acid, which induces resistance, the berry skin thickness can be increased in the case of thin-skinned grape varieties susceptible to rot (e.g., Rhine Riesling), thereby the insect damage rate can be reduced (Németh et al., 2020). The looser cluster structure by the treatments is also beneficial in preventing spread of the pest. In the current work, we present the results and experiences of the study series for the years 2021-2023.
