Mines in grapevine leaves were observed in July 2018 in a private vineyard located in the northwestern part of the country (village Butan).

Key words: Phyllocnistis vitegenella, Bulgaria, Vitis spp. INTRODUCTION Among invasive herbivore insects, leafminers represent an Ukraine, Turkey, Georgia, Kazakhstan,Uzbekistan, and important group. Many leafminers are known as economic Turkmenistan (Nieukerken et al., 2012; Cean, 2014; Fauna pests of agricultural crops (Kirichenko et al., 2018). They Europaea, 2018). This is the sixth record of the American are introduced to new continents and spread through grape leaf miner in Europe after Italy, Slovenia, various pathways such as horticultural trade and accidental Switzerland, Hungary and Romania. The species has a transport of adults and pre-imaginal stages in containers potential to become a serious pest for Bulgarian vineyards. and vehicles. They may also spread long distances with air This study reports P. vitegenella Clemens, 1859 currents (Kirichenko et al., 2018). Due to the lack of natural (Lepidoptera: Gracillariidae) as a new species for Bulgarian enemies in the new habitat, their effective control may be a fauna and a new pest on Vitis vinifera L. in the country. real problem. According to Kirichenko et al. (2018) in recent years, leafminers have attracted much attention due to increasing invasion records. Last few years, two species MATERIALS AND METHODS of leafminers originated from North America, invaded Old Continent and they are now being considered as serious Mines in grapevine leaves were observed in July 2018 in a pests for vineyards. These species are Phyllocnistis private vineyard located in the northwestern part of the vitegenella Clemens, 1859 (Lepidoptera: Gracillariidae) and country (village Butan). The leaves with symptoms, larvae Antispilla oinophylla van Nieukerken and Wagner, 2012 and adults were collected. The observations were recorded (Lepidoptera:Heliozidae) (Cean, 2014). In Europe, the with a digital camera. The biological materials (infested native leafminer, which is known to attack vineyards is leaves, larvae and adults) have been deposited at University Holocacista rivillei (Stainton, 1855) (Lepidoptera: of Forestry, Plant Protection Department, Laboratory of Heliozidae). It was recorded from French mainland, Greek Entomology, Sofia, Bulgaria. The nomenclature used here mainland, Italian mainland, Malta, Sicily, Slovenia, South for the genus Phyllocnistis Zeller, 1848 was according to European Russia, Spanish mainland, Croatia, Bulgaria, Fauna europaea (2018).

In Slovenia, the species was detected in 2004 Genus Phyllocnistis Zeller, 1848 is one of the more speciose (Seljak, 2005). In Switzerland, it was recorded in 2009 in genera in the Gracillariidae and currently, 90 valid names Ticino (south part of Switzerland) (Cara and Jermini, are known across the globe (Davis and Wagner, 2011). 2011). Later in 2014, the species was observed in Hungary In Europe the genus Phyllocnistis Zeller, 1848 is (Szabóky and Takács, 2014). In Romania, P. vitegenella was represented by 10 species, 4 of them known are from found for the first time in 2013, in the eastern part of the Bulgaria - Phyllocnistis labyrinthella (Bjerkander, 1790), country (Ureche, 2016). While in Bulgaria, mines made by Phyllocnistis saligna (Zeller, 1839), Phyllocnistis feeding larvae were detected in private vineyard in July unipunctella (Stephens, 1834) and Phyllocnistis 2018 on V. vinifera L. Probably the species entered Bulgaria valentinensis Hering, 1936 (Drenowski, 1909; Beiger, 1979; from Romania, where it has been detected since 2013. De Prins and De Prins, 2018; Fauna Europaea, 2018). The Several mines made by Phyllocnistis vitegenella were American grape leafminer is the fifth species from genus observed in each affected leaf (Figures 1 and 2). Although it Phyllocnistis found in Bulgaria. P. vitegenella was observed is a monophagus species and has a restricted host range, in Europe for the first time in 1995 in the north-east of occurring on Vitis spp., we found also several leaves with Academia Journal of Agricultural Research; Trencheva and Trenchev. 266 a b Figure 3a and b: Mine of Phyllocnistis vitigenella Clemens, 1859 on Parthenocissus quinquefolia (L.)
