“…The divergence time between Wolbachia supergroups A and B was estimated over 200 Mya (Gerth & Bleidorn, 2016), while Tagiadini speciation events were dated between 1.88 and 28.75 Mya. This implies that the cocladogenesis is impossible between Tagiadini Wolbachia and their hosts because the Wolbachia Although there is a growing number of studies indicating or proving horizontal transmission of Wolbachia among coleopteran hosts, mostly via common host plants or the foraging substrate such as dung (Kajtoch, 2022), the transmission pathways in Lepidoptera are unclear but could occur through feeding on common plants (Li et al, 2017;Sintupachee et al, 2006), sucking from the same mud-pools (Duplouy et al, 2020) and exposure to ectoparasitic mites (Gehrer & Vorburger, 2012;Jaenike et al, 2007), or parasitoids (Ahmed, Li, et al, 2015;Vavre et al, 1999). Since many butterfly larvae feed on plant tissue, and adults obtain nectar from flowers or tree sap, the close association of butterflies with plants might lead to transmission being mediated through the host plant (Sintupachee et al, 2006).…”

Wolbachia, one of the most ubiquitous heritable symbionts in lepidopteran insects, can cause mitochondrial introgression in related host species. We recently found mito‐nuclear discordance in the Lepidopteran tribe Tagiadini Mabille 1878 from which Wolbachia has not been reported. In this study, we found that 13 of the 46 species of Tagiadini species tested were positive for Wolbachia. Overall, 14% (15/110) of Tagiadini specimens were infected with Wolbachia and nine new STs were found from 15 isolates. A co‐phylogenetic comparison, divergence time estimation and Wolbachia recombination analysis revealed that mito‐nuclear discordance in Tagiadini species is not mediated by Wolbachia, but Wolbachia acquisition in Tagiadini appears to have occurred mainly through horizontal transmission rather than codivergence.

“…These groups are widely recognized as pathogens, parasites, or parasitoids of the infected species [72] but are still poorly studied. For instance, the intracellular bacteria of the genus Wolbachia are the most abundant endosymbionts, infecting many arthropods [73], and their pathogenic effects on Pj should be investigated.…”

The impact of invasive species is not limited to the loss of biodiversity; it also represents significant threats to agriculture on a global scale. The Japanese beetle Popillia japonica (native to Japan but an invasive agricultural pest in North America) recently occurred in the Po plain (Italy), one of the most cultivated areas in southern Europe. Thus, our aims were to identify (i) the main landscape predictors related to the occurrence of the Japanese beetle and (ii) the areas of potential invasion of the Japanese beetle in the two Northern Italian regions in which this invasive species currently occurs, Piedmont and Lombardy. Specifically, we combined Japanese beetle occurrences available in the citizen science online platform iNaturalist with high-resolution landscape predictors in an ensemble approach and averaged the results of Bayesian generalized linear and additive models developed with the integrated nested Laplace approximation (with stochastic partial differential equation). We found that the occurrence of the Japanese beetle was negatively related to the percentage of broadleaf forests and pastures, while it was positively related to sparse and dense human settlements as well as intensive crops. Moreover, the occurrence of the Japanese beetle increased in relation to the percentage of rice fields until a peak at around 50%. The Japanese beetle was likely to occur in 32.49% of our study area, corresponding to 16,000.02 km2, mainly located in the Po plain, low hills, and mountain valleys. We stress that the Japanese beetle is a high-risk invasive species in human-dominated landscapes. Thus, we strongly recommend that local administrations quickly enact pest management in order to reduce further spread.

“…We identified Rickettsia sequences from the following taxa: Staphylinidae: Scydmaeninae, Pseudophanias excavatus (Staphylinidae: Pselaphinae) and Curculionidae: Scolytinae; these are the first records of Rickettsia infection in the Scydmaeninae and Pselaphinae. The presence of Wolbachia in beetles has been extensively reviewed in several studies (Kajtoch and Kotásková 2018;Kajtoch 2022). We revealed the presence of Wolbachia in the following taxa: Histeridae, Staphylinidae: Tachyporinae and Staphylinidae: Scydmaeninae.…”

We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 species of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculionidae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylinidae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylonidae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp. (all Staphylinidae), Stelidota multiguttata Reitter, 1877, Lasiodites inaequalis (Grouvelle, 1914) (both Nitidulidae), Lagria scutellaris Pic, 1910, and Anaedus spinicornis Kaszab, 1973 (both Tenebrionidae). We also report the first cases of Rickettsia infections in Scydmaeninae and Pselaphinae. All data (sequences, metadata, and voucher photos) are made public in BOLD database and in a Zenodo Archive.
