RESUMEN
The spotted wing drosophila (SWD), Drosophila suzukii Matsumura (Diptera: Drosophilidae), is an invasive polyphagous pest of soft-skinned fruit that has started to threaten small fruit production in Europe since 2008. High reproductive capacity, short generation time, and difficulties in visualizing early damage contribute to its rapid spread. Currently, the control strategy against D. suzukii mostly relies on treatment with synthetic insecticides. Keeping in mind that this pest causes the greatest damage during the harvesting period, control using chemicals is not recommended due to the increased risk of high pesticide residue levels in the fruit. With the aim of reducing the use of insecticides, there is a need for developing an environmentally safer way of control. Alternative solutions could rely on the use of essential oils (EOs), which can be used in conventional and organic production systems. Four essential oils, geranium (Pelargonium graveolens), dill (Anethum graveolens), Scots pine (Pinus sylvestris), and bergamot (Citrus bergamia), were assessed for their insecticidal effects using four different tests (contact toxicity, fumigant-contact toxicity, repellent effect, and multiple-choice tests). The EOs applied were dissolved in acetone at three different concentrations. The most promising one was the geranium essential oil, which had the best effect in all conducted tests, even at the lowest applied concentration. Geranium oil caused very high mortality (95%), even at the lowest concentration applied, after 24 h in the fumigant-contact test, and it caused a mortality of over 85% in the contact test. It was also noticed that geranium demonstrated a deterrent effect by repelling females from laying eggs for four days after at the lowest applied concentration. Scots pine and dill EOs have moderate to strong effects in most tests. The mortality of 100% was achieved for the highest applied concentration in the fumigant-contact and contact tests. Bergamot EO did not have any significant insecticidal activity. Geranium, Scots pine, and dill have great potential to be used as an environmentally friendly way of controlling D. suzukii as they exhibit deterrent, repellent, and insecticidal effects.
RESUMEN
The topic of this study is the factors that influence the consumption of traditional food products (TFPs) in tourism, as seen from the perspective of management-sector employees in food and beverage catering facilities. The paper aims to analyse the economic, environmental, social, and touristic factors that highly influence the consumption patterns of catering facilities which are significant providers of traditional gastronomic experiences in tourism, by using the specially designed TFPct scale. The study was conducted on a sample of 300 catering facilities in AP Vojvodina (the Republic of Serbia). An explanatory factor analysis was used to confirm the key factors that influence the consumption of traditional products used to prepare the meals that are a part of what catering facilities offer. Subsequently, a binary logistics regression model was used to establish which of the indicated factors has a statistically significant effect on the management's decision to purchase these products for their catering facility. The study showed that the TFPct scale is appropriate for this type of research, and that economic factors are key factors in the consumption of traditional products. Moreover, compared with other types of catering facilities, interest in the consumption of these products is clearly expressed by a la carte restaurants.
RESUMEN
Background and aims: The gastronomic identity of an area is the key factor in tourism development, attracting numerous tourists and generating significant income. Numerous economic actors participate in its use and proper placement, and their perception of the gastronomic potential significantly affects its distribution and use in tourism. The main aim of this study is to investigate the factors of gastronomic identity that influence the development of tourism, observed at two tourist destinations in Southeast Europe [the Republic of Serbia (RS) the city of Novi Sad with Fruska Gora Mountain, n = 305 and Bosnia and Herzegovina (BIH) the city of Sarajevo with Jahorina Mountain, n = 301]. Methods: In order to define the factors that are relevant to food tourism development, a custom-made GastroIdentity scale was created. A survey was conducted among employees in the hospitality and tourism industry as well as employees in educational institutions in the field of hospitality and tourism. Results: The research results show that employees from the RS area acknowledge the importance of organizing gastronomic events where local products are presented and that they understand that dishes and beverages with unique and recognizable tastes can characterize their area. Employees from the BIH area pointed out that the nutritional quality of their local agricultural and gastronomic products represents an advantage when compared to mass-produced ones and that the local gastronomic culture and tradition are authentic representatives of the culture of the region. Conclusion: The GastroIdentity scale proved to be dependable, highlighting gastronomic culture and tradition as extremely crucial factors in tourism, using the input provided by the employees from the investigated areas. Noteworthy results were also recorded regarding the need for incentives for food tourism development in the investigated regions.
