Abstract
Background The Mediterranean Region represents a biodiversity hotspot with a high rate of endemism. In its western part, Corsica Island is notable in terms of biodiversity due to its large surface and its large range of habitats from seaside to alpine biotopes. Amongst diverse groups, insects, notably the main orders of pollinators composed of Coleoptera, Hymenoptera, Diptera and Lepidoptera, represent a good part of the insular richness. New information Our sampling effort focused on the insects from these four orders visiting flowers in a characteristic thermo-Mediterranean vegetation. Our database is an insight into the Corsican floral visitor biodiversity from three sites separated by a few kilometres in the region of Ajaccio during 13 months over two successive years. In total, 4012 specimens were sampled and 252 species or morpho-species identified from 133 genera and 47 families. Beetles were by far the most abundant order representing about 54% of the sampled specimens. The most diverse order was the Hymenoptera representing 39% of the species. Our continuous survey showed that these orders are temporally dynamic both between years and between seasons in terms of abundance and diversity.

Dewaele J, Barraud A, Hellström S, Paxton RJ, Michez D. A new exposure protocol adapted for wild bees reveals species-specific impacts of the sulfoximine insecticide sulfoxaflor. ECOTOXICOLOGY (LONDON, ENGLAND) 2024:10.1007/s10646-024-02750-2.

Abstract
Wild bees are crucial pollinators of flowering plants and concerns are rising about their decline associated with pesticide use. Interspecific variation in wild bee response to pesticide exposure is expected to be related to variation in their morphology, physiology, and ecology, though there are still important knowledge gaps in its understanding. Pesticide risk assessments have largely focussed on the Western honey bee sensitivity considering it protective enough for wild bees. Recently, guidelines for Bombus terrestris and Osmia bicornis testing have been developed but are not yet implemented at a global scale in pesticide risk assessments. Here, we developed and tested a new simplified method of pesticide exposure on wild bee species collected from the field in Belgium. Enough specimens of nine species survived in a laboratory setting and were exposed to oral and topical acute doses of a sulfoximine insecticide. Our results confirm significant variability among wild bee species. We show that Osmia cornuta is more sensitive to sulfoxaflor than B. terrestris, whereas Bombus hypnorum is less sensitive. We propose hypotheses on the mechanisms explaining interspecific variations in sensitivity to pesticides. Future pesticide risk assessments of wild bees will require further refinement of protocols for their controlled housing and exposure.

Exploring the hidden riches: Recent remarkable faunistic records and range extensions in the bee fauna of Italy (Hymenoptera, Apoidea, Anthophila). Biodivers Data J 2024; 12:e116014. [PMID: 38405380 PMCID: PMC10892157 DOI: 10.3897/bdj.12.e116014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Accepted: 12/29/2023] [Indexed: 02/27/2024] Open
Abstract
Background The area sourrounding the Mediterranean basin is recognised as a major biodiversity hotspot for bees, and Italy is amongst the European countries with the highest bee species richness. Detailed knowledge of bee distribution is crucial for understanding bee biology and designing tailored conservation strategies, but is still insufficient in southern European countries, especially in Italy. New information We report recent finds of 48 bee species that yield significant novelties for the Italian bee fauna. Eight species, namely Andrenaconfinis Stöckhert, Anthidiellumbreviusculum Pérez, Coelioxysalatus Foerster, Lasioglossumalgericolellum Strand, Megachilelapponica Thomson, Megachileopacifrons Pérez, Megachilesemicircularis auct. nec Zanden and Trachusaintegra Eversmann are reported as new for Italy. In addition, Andrenabinominata Smith, Andrenacompta Lepeletier, Colletesacutus Pérez, Lasioglossumstrictifrons Vachal, Rhodanthidiumsiculum Spinola and Rhodanthidiumsticticum Fabricius are newly recorded from mainland Italy, Osmiaheteracantha Pérez from Sardegna and Nomadaflavopicta Kirby from Sicilia. We also report significant range extensions for other bee species and recent records of species that had long gone unrecorded in Italy. The combination of morphology and DNA barcoding provided reliable identifications even for the most challenging specimens. As several of our records come from areas neglected by bee experts in the past, this study stands out as a key indicator of a bee faunistic richness still awaiting discovery and hopefully it will stimulate the interest of taxonomists and stakeholders in pursuing bee research in Italy in the near future.

Abstract
The present study is an update to the first catalogue of Russian bees published in 2017. For the Russian fauna, five recently described species are reported, as well as 45 species newly recorded since the first catalogue (including one invasive species), nine species overlooked in this previous Russian checklist, and 17 published synonymies. Original records are provided for nine species previously unknown to Russia and, as a taxonomic act, one species, Anthidiumovasi Warncke, 1980, syn. nov., is synonymised with Icteranthidiumfloripetum (Eversmann, 1852). Additionally, 14 species are excluded from the original catalogue and numerous other taxonomic changes and clarifications are included. The present work revises the total number of genera for Russia to 64 and the total number of species to 1,268.
