Abstract

Drosophila suzukii (Matsumura, 1931) is an invasive oligophagous pest native to southeastern Asia. The first documented report of this pest in Serbia was in 2014. The insect is a pest of healthy and physiologically mature (ripening) soft fruits. The aim of the study was to determine the efficiency of different types of baited traps in mass trapping specimens of this species in raspberry plantings. Five types of blends (attractants) were used for mass trapping. The experiment was set up on May 27th, 2017. Inspection and sample collections were carried out at 7-10 day intervals from June 4th to July 31st, 2017. Based on the analysed field data, we confirmed that standard trap S was the most efficient, with 8099 specimens caught in the experimental period. The number of caught specimens decreased in the deployed traps, as follows: trap T4 (695), trap T3 (682), trap T2 (643), and trap T1 (482) as the least efficient. Statistical analyses showed very significant differences between the standard trap and trap T1, and significant differences between the standard trap and the other trap types in the average number of caught specimens. No significant differences in trapping were found between the other trap types.

Highlights

The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura, 1931) (Diptera, Drosophilidae) is an invasive oligophagous pest native to southeastern Asia (Asplen et al, 2015)
The highest efficiency in the first examination was shown by attractant S, with an average catch of 53.85 adults per trap, followed by the attractants T4, T2, and T1 as the least effective (Figure 2)
The highest average number of adults in the growing season was caught by attractant S (245.42 specimens per trap), followed by the attractants T4 (115.83), T3 (113.67) and T2 (107.16)

Summary

Introduction

The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura, 1931) (Diptera, Drosophilidae) is an invasive oligophagous pest native to southeastern Asia (Asplen et al, 2015). Ecological plasticity and a wide range of host plants enabled survival and spread in the territory of introduction (Zerulla et al, 2015). European countries, such as Italy (2009), Spain (2010) and France (2010), have established pest monitoring and control programmes (Cini et al, 2012). The species was probably introduced to Serbia through fresh fruit imports at the Horgoš border crossing. In Serbia, SWD is a very important pest of small fruits, primarily raspberry (Tošеvski et al, 2014), as still one threat in this production behind newer identified (Tanasković and Milenković, 2009). The harmful effects of this insect are observed during purchase or later during proccessing, and this is the main reason for justified concerns of raspberry producers, purchasers and processors
