Abstract (croatian)

Prema podatcima FAOSTAT-a iz 2018. površine pod kukuruzom zauzimale su približno 1,147 milijarda hektara. Kukuruz je uz pšenicu, rižu i krumpir najvažnija svjetska kultura. U Hrvatskoj je oko 250 000 ha oranica zasijano kukuruzom pa možemo reći da je kukuruz najvažnija kultura i u Hrvatskoj. Jesenska sovica (Spodoptera frugiperda, J.E. Smith) važan je štetnik kukuruza iz porodice sovica (lat. Noctuidae). Štete pričinjavaju gusjenice koje se hrane na listovima biljaka te mogu uzrokovati potpunu defolijaciju i ugibanje biljke. Gusjenice jesenske sovice hrane se s 80 različitih biljaka, a preferiraju kukuruz. Dugo vremena štetnik je bio prisutan samo u Americi, međutim 2016. ovaj je štetnik prvi put uočen i u centralnoj i zapadnoj Africi. Tijekom dvije godine jesenska sovica proširila se gotovo po cijelom afričkom kontinentu. Podatci o širenju iz lipnja 2019. govore o prisutnosti štetnika u Egiptu što je dosad najbliže Europi. S obzirom na iznimno brzo širenje štetnika tijekom protekle tri godine opravdana je sumnja i strah da bi štetnik mogao vrlo brzo stići u Europu. Iznimno je važno na vrijeme obavijestiti poljoprivrednike o važnosti ovog štetnika koji može ozbiljno ugroziti proizvodnju kukuruza u Europi.

Abstract (english)

According to FAOSTAT in 2018 the maize was sown on approximately 1.147 billion ha. Along with wheat, rice, and potatoes, maize is the world's most important crop. In Croatia, out of 815,000 ha of arable land, about 250,000 ha are sown with maize, so we can also say that corn is the most important crop in Croatia too. The fall armyworm (Spodoptera frugiperda, JE Smith) is an important pest of maize from the Noctuidae family. Damages are caused by larvae that feed on the leaves and can cause complete defoliation and destruction of the plant. Fall armyworm larva can feed on 80 different plant species with a preference for maize. For a long time, the pest was present only in America, however, in January 2016 this pest was observed for the first time in Central and West Africa. During two years, the fall armyworm almost has spread across the entire African continent. Expansion data from June 2019 indicate the presence of the pest in Egypt, which is the closest to Europe so far. Given the extremely rapid spread of the fall armyworm over the past three years, the fear that the pest could reach Europe very quickly is justified. It is extremely important to inform farmers about the harmfulness and importance of this pest, which can seriously jeopardize maize production in Europe.
