First record of alien species Chymomyza amoena [Diptera

Abstract

Strana vrsta Chymomyza amoena (Loew 1862) zabilježena je prvi puta u Hrvatskoj. Ova fitofagna vrsta octene muhe porijeklom iz Sjeverne Amerike otkrivena je u Europi 1975. godine na području nekadašnje Čehoslovačke, a već 1980. godine zabilježena u dvije nama susjedne države (Mađarskoj i Srbiji). Smatra se da se C. amoena proširila uvozom jabuke iz Amerike u Europu, a velik broj dostupnih biljaka domaćina (domaće jabuke, engleski hrast te europski kesten) zaslužan je za široku rasprostranjenost vrste u Europi. U radu se navode biljke domaćini, morfologija i biologija vrste, lokalitet prvog pronalaska, te se prognozira širenje vrste na području Hrvatske. C. amoena razvija se u različitim vrstama orašastih, jezgričavih i koštićavih plodova oštećenim od primarnih štetnika, te se smatra jedinom vrstom octene muhe s ovakvim razvojnim navikama u Sjevernoj Americi i Europi. Poznati domaćini u Europi su šumske vrste (kesten i hrast crnika) te voćne vrste (jabuka, divlja trešnja i šljiva). C. amoena ne pričinjava primarne štete u uzgoju, stoga se ne smatra štetnikom u poljoprivredi i šumarstvu. Dva primjerka vrste pronađena su tijekom 2016. godine u vinogradu na području Međimurske županije okruženim šumom i zapuštenim voćnjakom jabuke. S obzirom da je Međimurska županija poznata voćarska regija, a u relativnoj blizini u okolici Medvednice, Hrvatskom zagorju i Samoborskom gorju nalaze se i kestenove sastojine, pretpostavlja se da bi vrsta mogla biti proširena na području Sjeverozapadne Hrvatske, te na drugim sastojinama pitomog kestena u Hrvatskoj. Rad predstavlja prvi nalaz vrste C. amoena na području Hrvatske, te pruža nove uvide o rasprostranjenosti vrste u Europi.

The Impact of Beehive Proximity, Human Activity and Agricultural Intensity on Diptera Diversity in a Mediterranean Mosaic of Agroecosystems, with a Focus on Pest Species

“…The presence of Chymomyza amoena has been confirmed in the northern part of Croatia [ 30 ], and this study has revealed its presence at six new localities in the Istria region. The collecting localities are surrounded by Mediterranean forests and extensive production of grapes, figs, and sweet cherries.…”

“…Drosophila suzukii (Matsumura, 1931) was the most abundant invasive alien species found at every sampling site. Moreover, we found a total of 34 specimens of Chymomyza amoena (Loew 1862); this species was previously confirmed only twice in Croatia [ 30 , 47 ]. Callopistromyia annulipes was also found in fourteen locations with 265 specimens, representing the second record in Croatia.…”

“…More than 200 species of Diptera are considered pests infesting ripening fruits [ 27 , 28 , 29 ]. Alien species of Diptera have exponentially increased in Europe since the second half of the 20th century [ 30 ]. Most alien pests in Europe were introduced unintentionally, and almost one-third originate from North America.…”

Fallen fruit: A backup resource during winter shaping fruit fly communities

“…It is not considered a true pest (Band & Band, 1980;Pajač Živkovi c et al, 2017) at present and has received much less research attention than D. suzukii. Native to North America, it has become widely established in Europe since its first detection in 1975 in Czechia (Band et al, 2005;de Jong & van Zuijlen, 2003;Pajač Živkovi c et al, 2017).…”

“…Worldwide, communities of frugivorous species have been impacted by invasive exotic species. For instance, in Europe, the invasive members of the Drosophilidae family, Drosophila suzukii Matsumara and Chymomyza amoena Loew, are highly polyphagous and could profoundly alter the structure of Drosophilidae communities developing in fresh and decaying fruit by using the same resources as native species (Band et al, 2005; Pajač Živković et al, 2017; Poyet et al, 2014, 2015).…”
