Abstract

Lisni miner vinove loze strana je invazivna vrsta leptira iz porodice Gracillariidae porijeklom
iz Sjeverne Amerike otkrivena na području Europe 1995. godine. U Hrvatskoj je vrsta
utvrđena 2010. godine, no njezina rasprostranjenost i štetnost slabo je istražena. Gusjenice
štetnika hrane se lisnim parenhimom te oblikuju dugu krivudavu minu u listu čime se
smanjuje njegova asimilacijska površina i list se prijevremeno suši. Cilj rada bio je utvrditi
prisutnost lisnog minera vinove loze u vinogradima pokušališta Jazbina. Štete od lisnog
minera vinove loze utvrđene su vizualnim pregledom vinove loze tijekom jeseni 2023. godine
u vinogradu u kojemu se uzgaja sortiment otporan na plamenjaču i pepelnicu vinove loze.
Ukupno je pregledano 380 trsova različitih sorata vinove loze a štete su utvrđene na više od
20 % pregledanih trsova. U prosjeku su kod svih istraživanih sorata štete utvrđene na dva lista
po trsu a prosječna oštećenja iznosila su 1,5 cm2 po listu. Prisutnost lisnog minera vinove loze
po prvi put je utvrđena na pokušalištu Jazbina. Iako nisu zabilježene značajne štete u uzgoju
vinove loze, zbog invazivnog karaktera vrste te ubrzanog širenja na području Europe
preporučuje se redovito pratiti njegovu populaciju.

Abstract (english)

The grapevine leafminer is an invasive species of moth from the family Gracillariidae,
originating from North America, and it was discovered in Europe in 1995. In Croatia, the
species was identified in 2010, but its distribution and harmfulness are poorly researched. The
larvae of the pest feed on the leaf parenchyma, creating long winding mines in the leaf, which
reduces its photosynthetic area and causes the leaf to dry out prematurely. The aim of this
study was to determine the presence of the grapevine leafminer in the vineyards of the Jazbina
experimental station. Damage from the grapevine leafminer was determined by visual
inspection of grapevines during the autumn of 2023 in a vineyard cultivating varieties
resistant to downy mildew and powdery mildew. A total of 380 vines of different grape
varieties were inspected, and damage was found on more than 20% of the inspected vines. On
average, all investigated varieties had damage on two leaves per vine, with average damage of
1.5 cm² per leaf. The presence of the grapevine leafminer was confirmed for the first time at
the Jazbina experimental station. Although significant damage to grapevine cultivation was
not recorded, due to the invasive nature of the species and its rapid spread across Europe, it is
recommended to regularly monitor its population.
