Spread of the spotted wing drosophila - Drosophila suzukii ( Diptera, Drosophlidae) and new distribution records in Dalmatia region of Croatia.

A specific survey for the detection of Drosophila suzukii Matsmura 1931 (Diptera, Drosophilidae) in Dalmatia region of the Republic of Croatia during 2013, confirmed that the pest is present and widespread. Adults were detected in traps suspended in Prunus cerasus L. (sour cherry), Prunus persica L. (peach), Ficus carica L. (fig) and Morus alba L. (mulberry) orchards and individual trees, during the fruit maturation period, in 16 (of the 51 locations) where traps were placed in Dubrovačko-neretvanska, Splitsko-dalmatinska, Šibensko-kninska and Zadarska counties. This confirmed the rapid spread of D. suzukii in Croatia and this pest is a great concern for areas that are not yet infested that have favourable conditions for the pests' development. The results of the survey highlight the importance of the development and implementation of long-term sustainable control. [ABSTRACT FROM AUTHOR]
