The development of drosophilid species (Diptera, Drosophilidae) in different strawberry cultivars

Development of spotted wing drosophila in fruits of two raspberry cultivars

“…Similarly, this research of the development of spotted wing drosophila on different raspberry cultivars confirmed its dominance in another crop in Croatia. In Croatia the development of drosophilid species in the greenhouse production of strawberries was studied and although the presence of D. suzukii was confirmed, its dominance has not been established since the native drosophilid species D. simmulans develops mostly in strawberry (Pajač Živković et al, 2019).…”

“…In both raspberry cultivars, female dominance was recorded, which implies that further population increase can be expected. From a biological point of view, female-dominated insect populations have better biological potential (Pajač Živković et al, 2019), which means that such populations will continue to grow and expand in the future. The results of of research confirmed the dominance of D. suzukii species in agroecological systems of fruit growing in greenhouses in Croatia, and its preference for raspberry cultivar 'Amira'.…”

“…Very rapidly, infested fruit begin to deteriorate around the feeding area (OEPP/EPPO 2010). The affected fruits are susceptible to attack by other drosophilids and secondary pathogens which represents indirect damage (Walsh et al, 2011, Pajač Živković et al, 2019. All these characteristics make this fly a serious threat for agriculture on global level (Hauser et al, 2009, De Ros et al, 2015.…”

“…The first economic damages made by spotted wing drosophila in Croatia were detected in commercial production of fresh strawberries in 2016 (Pajač Živković et al, 2019). Except on strawberries, this species is a potentially important pest on other berries like raspberries.…”
