## 1 Introduction  
_Drosophila suzukii_ ([PERSON]) (Diptera: Drosophila), commonly known as the spotted wing drosophila (SWD), is a dipteran insect belonging to the family Drosophila. This species was first reported in Japan, causing damage to cherries in 1916, but it was not formally described by [PERSON] until 1931, when it was named SWD or cherry fruit fly [1; 2]. The first record of this dipteran outside Asia was in 1980, specifically in Oahu, Hawaii (USA) [3]. By 2008, its presence was recorded in North America and Europe. In North America, it was reported in the state of California, and by 2010, it was invading different states such as Utah, Louisiana, North Carolina, South Carolina, Wisconsin, and Michigan [4] before reaching British Columbia (Canada). Subsequently, in 2011, it was detected in the state of Michoacan, Mexico [5]. In Europe, the first records of SWD were in Spain (Cataluna) and Italy (Toscana), expanding in 2012 to the Iberian Peninsula [3]. Only one year later, the first records of SWD in South America occurred. In 2013, the presence of SWD was reported in the Brazilian states of Santa Catarina and Rio Grande [6]. Later in the same year, it was detected in Uruguay (Montevideo and in the rural area of Empalme Maldonado) [7]. For Argentina, the presence of SWD was recorded in 2014 in blueberries, in the town of Lobos, province of Buenos Aires [8]. [PERSON] et al. [9] report interesting background information on the presence of SWD in Chile. The first record of this occurrence was in 2016; however, this identification was erroneous, which was corrected in time by EPPO [10], confirming its absence in the country for that year. However, in 2017, the Agricultural and Livestock Service (SAG), through the specific surveillance system for the pest, detected SWD for the first time in Chile through the capture of adult specimens in traps installed at the border crossing with Argentina, Mamuil Malal (Villarrica-Pucon path, 39\({}^{\circ}\)34\({}^{\prime}\)43\({}^{\prime\prime}\) S, 71\({}^{\circ}\)29\({}^{\prime}\)16\({}^{\prime\prime}\) W) in the La Araucania Region, southern Chile [11]. The damage caused by this species is attributed to the oviposition of eggs beneath the skin of ripe or ripening fruits. For example, females lay 1-3 eggs per fruit in up to 7-16 fruits per day [12]. Larvae hatch and feed on the fruit pulp, resulting in a loss of turgor, which leads to fruit collapse and a reduction in its commercial value [13]. In the USA, SWD caused annual losses estimated at USD 511 million in 2008, affecting crops such as strawberries, cherries, raspberries, blueberries, and blackberries [14]. In Maine (USA), studies have projected that the economic impact of SWD on wild blueberries could amount to approximately USD 6.8 million, with a 30% reduction in production [15]. In Chile, predictive models have been developed to estimate the potential impacts of SWD on grapevines and cherry trees, indicating that infestation levels could reach 56% and 79%, respectively [9]. Before implementing any pest management plan, it is crucial to understand the behavior and life cycle of the pest throughout the season [16]. Integrated Pest Management (IPM) programs for SWD commonly use commercially available traps and lures for monitoring [17]. Various attractants, such as apple cider vinegar, wine, yeasts, and their mixtures, have been evaluated to identify the most effective components for characterizing SWD pest pressure, yielding mixed results [18; 19; 20; 21; 22; 23]. Another widely used method is the use of liquid baits and mass trapping. However, both methods have some drawbacks due to the need for timely bait replacement, difficulty in SWD identification due to the need for sifting, and the presence of microorganisms (fungi) [24; 25; 26; 27]. Thus, the search for new alternatives becomes essential to support the work carried out by the SAG, the state agency responsible for environmentally friendly quarantine surveillance, and to apply new technologies.
