“…Invasive insect species pose a considerable threat to biodiversity and economy all over the world. The biogeographical barriers formerly limiting species to their native range have been overcome due to globalization, and the number of unintentionally introduced arthropods, including many harmful phytophagous ones, seems to be increasing rapidly in Europe (Blank et al ., 2010; Cardaş et al ., 2011; Matošević, 2012; Matošević & Pajač Živković, 2013; Vétek et al ., 2016; Holuša et al ., 2017; Zúbrik et al ., 2017; Belitskaya et al ., 2018; Dautbašić et al ., 2018; Forest Research, 2018; Bălăcenoiu et al ., 2020). Although it would be hard to estimate all costs incurring after the establishment of an alien pest in the invaded territories, detailed knowledge about the biology and behaviour of the particular species may largely help implement impact assessments and make adequate decisions subsequently.…”

“…Although this species was described in Japan as early as 1939 (Takeuchi, 1939), the number of available reports on its damage to elms in East Asia is limited. Since its first records from Poland and Hungary in 2003, the range of A. leucopoda has expanded to many countries of the continent, including Romania (Bălăcenoiu et al ., 2020; Cardaş et al ., 2011), Russia (Belitskaya et al ., 2018), Bosnia Herzegovina (Dautbašić et al ., 2018), Slovakia (Zúbrik et al ., 2017), Czech Republic (Holuša et al ., 2017), Croatia (Matošević, 2012; Matošević & Pajač Živković, 2013) and Great Britain (Blank et al ., 2010; Vétek et al ., 2016; Forest Research, 2018). The species reproduces by thelytokous parthenogenesis and is able to develop through several generations a year (Blank et al ., 2010; Papp et al ., 2018; Papp, 2018; Vétek et al ., 2020), which facilitate the rapid spread of this pest if the host plant is available and consequently result in mass infestations.…”

Although much research has been carried out to develop taxa resistant to Dutch elm disease (DED), newly occurring pests represent a new challenge for the protection of elms (Ulmacae). The invasive zigzag elm sawfly (Aproceros leucopoda) is a recent invader of Asian origin in Europe defoliating elm trees that are otherwise often characterized with major resistance to DED. The range expansion of this pest poses a major threat to elms. The aim of this study was to identify the susceptibility of Ulmus crassifolia, Hemiptelea davidii and Zelkova serrata to this pest by using three different methods (oviposition trials with cut shoots and with plants in pots, and larval feeding trials with plants in pots) to define the performance of A. leucopoda on potential hosts. The fact is that A. leucopoda was unable to complete its development on either of these three taxa of Ulmaceae, whereas Ulmus pumila (the reference during the trials) was again confirmed as a true host of the pest clearly indicating that the host plant range of A. leucopoda is probably limited not only to Ulmus but also within this genus. Our results may be considered in future resistance breeding programmes, pest risk assessments, and for the selection of Ulmaceae species.

The elm zigzag sawfly (EZS), Aproceros leucopoda Takeuchi, was detected in the United States for the first time in Virginia in 2021. In 2022, it was confirmed in 4 additional states: Pennsylvania, North Carolina, Maryland, and New York. These are the first records of this species in the United States and demonstrate a rapid range expansion of an invasive defoliating pest. Native to Asia, EZS feeds exclusively on Ulmus spp. (elms; Ulmaceae). In the United States, feeding damage ranges in severity from minor to severe. Young instars create a zigzag-shaped pattern in leaves as they feed, while older larvae feed more completely on foliage, leaving only the midvein and sometimes thick lateral veins. This more complete feeding often obscures the signature zigzag defoliation of younger instars. Long-term health impacts to host trees are unknown, though aesthetic damage, growth loss, and branch dieback occur in Europe where it is also invasive. Little is known about management options for this pest, and continued expansion of this species’ range in the United States is expected.
