Abstract

Spotted lanternfly Lycorma delicatula is an emergent invasive agricultural pest native to China, and has invaded the Republic of Korea ([i.e., South Korea] first detected 2006), Japan (2009), and the United States of America (2014). Previous reports from the Republic of Korea and the United States on L. delicatula detail rapid population expansion and severe feeding damage to crop and non-crop host plants following its invasion. In contrast, populations in Japan initially spread slowly and remained isolated to two prefectures (Ishikawa and Fukui) for 8 years post-invasion without any reports of agricultural damage. Here we update the current known distribution of L. delicatula in Japan through field surveys and complete a comprehensive review of formally published literature and community scientist reports. Recently L. delicatula has expanded its range in Japan with six new prefectural detections in the last 2 years. Phylogenetic analyses were performed using whole mitochondrial genome sequences of specimens collected across Japan to elucidate the genetic makeup and potential source areas of these populations. Phylogenetic analyses suggest the putative area of origin of Japanese L. delicatula populations is the north-central region of China, as opposed to the invasive populations in the Republic of Korea and in the United States, which both originate from the eastern region of China. Results presented here provide a better understanding of the factors influencing the invasion dynamics of L. delicatula, which could enable development of improved biosecurity, monitoring, and incursion management programs for this pest.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Population Ecology due to its progression and the good impact it has achieved in recent years, according to the agency Scopus (SJR), it has become a reference in its field. In the year of publication of the work, 2025, it was in position , thus managing to position itself as a Q2 (Segundo Cuartil), in the category Ecology, Evolution, Behavior and Systematics. Notably, the journal is positioned en el Cuartil Q4 for the agency WoS (JCR) in the category Ecology.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-05-12:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 4.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 2 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 0.5.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: http://hdl.handle.net/20.500.12327/3586
