“…Our work represents a case study demonstrating that community-based control efforts in which members of the public are invited to serve as citizen scientists can achieve population suppression under the appropriate settings (e.g., public river access, limited range of invasive species). Given the sometimes-high cost and challenge of funding control programs in perpetuity, community engagement and involvement in tournaments or bounty hunts represents a tractable approach to achieving management goals (Wallace et al 2021 ).…”

Control of non-native, invasive species in groundwater-dependent ecosystems that are also inhabited by regionally endemic or at-risk species represents a key challenge in aquatic invasive species management. Non-native suckermouth armored catfish (SAC; family Loricariidae) have invaded freshwater ecosystems on a global scale, including the groundwater-dependent upper San Marcos River in Texas, USA. We used passive integrated transponder tags to follow the movements and fates of 65 fish in a 1.6 km spring-fed reach of the upper San Macros River to assess the efficacy of a community-based spearfishing bounty hunt for controlling SAC. We found the weekly probability of SAC survival was negatively correlated with the number of fish removed as a part of the bounty hunt each week ( P = 0.003, R 2 = 0.86), while the probability of SAC being speared and reported was positively correlated with the number of fish removed ( P = 0.011, R 2 = 0.53). The majority of SAC used < 25 m 2 of river over a nine-week tracking period, but the area of river fish used correlated positively with the number of relocations ( P < 0.001, R 2 = 0.36) as might be expected for a population that disperses through diffusive spread. These findings collectively suggest local-scale suppression of the SAC population is possible through community engagement in spearfishing, but over longer time periods immigration might offset some of the removal success. This conclusion provides an explanation for the pattern in which long-term spearfishing tournaments have reduced biomass but ultimately not resulted in eradication of the population.

“…Data collection and monitoring of non-native species, especially if not directed towards specific target taxa of medical, economic or phytosanitary interest, is, however, generally difficult to implement on a national scale; in this regard, the contributions deriving from the non-professional entomological community and citizen-science initiatives prove to be fundamental (e.g. Crall et al (2010) , Larson et al (2020) , Wallace et al (2021) ). This work aims to share faunistic data on Italian non-native beetles in a standard and easily accessible format, updating the distribution or confirming the establishment of some taxa and reporting the arrival of further species.…”

In the last decades, climate change and globalisation have been exacerbating the introduction of non-native beetles worldwide. Due toits peculiar territory, climate and geographical position in the middle of the Mediterranean Basin, Italy is one of the European countries with the highest number of intercepted, adventive and established non-native beetles, some of which are invasive. In this perspective, producing new faunistic records and continuously updating reliable and easily accessible distributional data is a fundamental step in investigating and potentially preventing further species introduction. The aim of this contribution is to report and discuss new faunistic records of non-native Coleoptera in Italy. For some species, new records enlarge the previously-known distribution (e.g. the ambrosia beetles Anisandrus maiche (Kurentzov, 1941) and Cnestus mutilatus (Blandford, 1894) or the click beetle Monocrepidius posticus (Eschscholtz, 1829)), while for others (e.g. the scarab beetle Archophileurus spinosus Dechambre, 2006), data confirm their establishment and highlight a possible expansion phase. The false powderpost beetles Ptilineurus marmoratus (Reitter, 1877) and the longhorn beetle Xylotrechus chinensis (Chevrolat, 1852) are two new additions to the Italian fauna, while the establishment of the monotomid beetle Monotoma americana Aubé 1837 is confirmed.
