Abstract

Orahova muha invazivna je vrsta porijeklom iz Sjeverne Amerike. Ličinke orahove muhe hrane se plodom oraha čime se smanjuje njegova tržišna i nutritivna vrijednost. U Hrvatskoj je vrsta prvi put zabilježena 2004. godine na području Istarske i Primorsko goranske županije, a u narednim godinama proširila se na kontinentalni dio Hrvatske. U istraživanju je praćena populacija orahove muhe u voćnjaku na području Svete Nedelje (lokalitet Strmec). Dinamika populacije štetnika praćena je od kraja lipnja do sredine listopada 2019. godine pomoću Csalomon® PALz žutih ljepljivih ploča s dodatkom sintetskog hranidbenog atraktanta postavljenih na solitarno stablo oraha. Ulov štetnika je započeo 5. srpnja te je trajao do 4. listopada 2019. godine. Ukupno je ulovljeno 680 odraslih jedinki orahove muhe što je dokaz udomaćenosti vrste na području istraživanja. Rezultati ovog istraživanja prilog su poznavanju dinamike populacije i rasprostranjenosti štetnika na području Zagrebačke županije.

Abstract (english)

The walnut husk fly is an invasive species native to North America. The larvae of the walnut husk fly feed on the fruit of the walnut, which reduces its market and nutritional value. In Croatia, the species was first recorded in 2004 in the Istria and Primorje-Gorski Kotar County, and in the following years it spread to the continental part of Croatia. In this study the population of the walnut husk fly was monitored during the 2019 vegetation season in an orchard in the area of Sveta Nedelja (Strmec locality). The pest population dynamics was monitored in the period from the end of June to the middle of October 2019 using Csalomon® PALz yellow sticky traps with the addition of synthetic food-attractant placed on a solitary walnut tree. The catch of pests began on July 5 and lasted until October 4, 2019. A total of 680 adult walnut husk flies were caught, which is evidence of the species' domestication in the study area. The results of this research are a contribution to the knowledge of population dynamics and pest distribution in the Zagreb County.
