Bark and ambrosia beetles (Coleoptera, Scolytinae) are amongst the most important wood-boring insects introduced to Europe. During field investigations conducted between 2019 2021 in different countries regions of Europe, many exotic species have been recorded providing new relevant data. Dryoxylon onoharaense (Murayama, 1933) is Europe for first time. Xyleborinus attenuatus (Blandford, 1894) a Italy, while Xylosandrus germanus 1894), Hypothenemus eruditus (Westwood, 1836) Amasa sp. near A. truncata country records Portugal. Cnestus mutilatus Phloeotribus liminaris (Harris, 1852) were collected Italy was France after discovery, confirming their establishment dispersal into areas.

Volatiles from nutritional fungal symbiont influence the attraction of Anisandrus maiche (Coleoptera: Curculionidae) to ethanol-baited traps

Environmental Entomology, Год журнала: 2024, Номер 53(1), С. 108 - 115

Опубликована: Янв. 10, 2024

Abstract Anisandrus maiche Stark (Coleoptera: Curculionidae: Scolytinae) is a non-native ambrosia beetle from central Asia that has been spreading throughout the eastern United States since 2005. Preferred hosts of A. are not well characterized within its currently invaded range, but it established in managed and natural forests Indiana. Current monitoring detection efforts for this rely on ethanol-baited traps, fungal volatiles may alter attraction to ethanol. In study, we conducted trapping experiments Indiana determine extent which suite common alcohols influences response traps. We then evaluated isoamyl isobutyl alcohol as potential attractants their ability enhance Lastly, used SPME-GC-MS identify Ambrosiella cleistominuta (Mayers & Harr.), symbiont maiche, grown 7 14 days malt extract agar. Benzyl alcohol, hexanol, methyl phenylacetate, phenethyl piperitone reduced traps field. Moreover, adding benzoate individually did further increase capture. When paired with ethanol, repelled beetles early flight period significantly trap capture during fall flight. These results represent first step understanding role colonization behavior ultimately inform management strategies species.

Ambrosia beetles are highly successful as invaders because they often transported internationally with wood packaging and other products their inbreeding mating systems facilitates establishment of invading populations. In 2022, two independent insect surveys in canton Ticino (southern Switzerland) revealed the widespread occurrence invasive ambrosia beetle Anisandrus maiche (Kurentzov, 1941) from southern to central-upper Ticino. This species is native east Asia has previously been found a non-native United States, Canada, western Russia, Ukraine and, 2021, northern Italy. Here, we present results several trapping studies using different trap types (bottle traps, funnel traps Polytrap intercept traps) attractants map distribution species. total, 715 specimens A. , all female, were trapped, identity selected individuals was confirmed by morphological molecular identification based on three mitochondrial nuclear markers (COI, 28S CAD). Trap samples early April September 2022 intervals four weeks showed that flights occurred mainly June mid-August.

New records of non-native Coleoptera in Italy

In the last decades, climate change and globalisation have been exacerbating introduction of non-native beetles worldwide. Due toits peculiar territory, geographical position in middle Mediterranean Basin, Italy is one European countries with highest number intercepted, adventive established beetles, some which are invasive. this perspective, producing new faunistic records continuously updating reliable easily accessible distributional data a fundamental step investigating potentially preventing further species introduction.The aim contribution to report discuss Coleoptera Italy. For species, enlarge previously-known distribution (e.g. ambrosia Anisandrusmaiche (Kurentzov, 1941) Cnestusmutilatus (Blandford, 1894) or click beetle Monocrepidiusposticus (Eschscholtz, 1829)), while for others scarab Archophileurusspinosus Dechambre, 2006), confirm their establishment highlight possible expansion phase.

The introduction of non-native organisms into new areas may pose major threats to natural ecosystems. Therefore, continuous and careful national surveys for the interception invasive species are necessary. During survey quarantine in 2023, two ambrosia beetles, Anisandrus maiche (Kurentzov) Xylosandrus compactus (Eichhoff), were recorded Slovenia. was three locations eastern part Slovenia, with a total 386 individuals. Three individuals collected one location near port Koper. We discuss possible pathways dispersal.

Trap captures of invasive ambrosia beetles (Coleoptera: Curculionidae) as influenced by ethanol release rate

Abstract Infestations of ambrosia beetles in the tribe Xyleborini (Coleoptera: Scolytinae) are associated with economic losses to horticultural trees due branch die‐back and tree death. Ethanol is a key attractant used for monitoring flight activity. Trapping experiments were conducted woodlots Ohio, USA, Veneto, Italy, characterize effect ethanol release rate on captures Anisandrus maiche , Xyleborinus saxesenii Xylosandrus crassiusculus germanus . In Ohio (2019, 2020 2021) Italy (2021), traps baited centrifuge tubes that modified achieve rates 0.1–13.2 g/day. (2022), varying quantities manufactured lures 0.02–1.4 There was no consistent relationship between trap tubes. nine sixteen analyses, releasing at 1.1 g/day or higher collected more A. X. than 0.1 contrast, 0.1–1.4 attracted 0.02–0.05 This comprehensive study provides important insights into tactics along implications optimizing ethanol‐baited as part ‘push‐pull’ strategy whereby repellents ‘push’ away from vulnerable attractants ‘pull’ them annihilative traps.

Abstract The non-native wood-boring and symbiotic fungus-culturing Xylosandrus germanus (Blandford) was first reported in New York apple orchards 2013. Trapping surveys have been conducted annually since to assist growers timely applications of preventative control measures. In 2021, a similar-looking introduced species, Anisandrus maiche (Kurentsov), identified traps west central York. recorded 2005 Pennsylvania but its history unclear due potential misidentification. We collected ambrosia beetles using ethanol-baited bottle 2022 2023 at 2 commercial near Lake Ontario cider the lower Finger Lakes district. Traps were placed forest interior, edge, orchard edge each site. trapped from mid-April into early October; it abundant region less so Lakes. contrast, counts A. very high extremely low Ontario. It late-May mid-September. Most other bark beetle species uncommon. Captures X. generally highest interior declined toward usually present across habitats same time. Thus, practice trapping edges should continue. Both can potentially infest stressed trees, including orchards, throughout growing season.

Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae) in chestnut‐growing areas in north‐west Italy

EPPO Bulletin, Год журнала: 2025, Номер unknown

Опубликована: Май 21, 2025

Abstract Field surveys were carried out to deepen knowledge about the ambrosia beetle community in sweet chestnut‐producing areas north‐west Italy. They where Castanea sativa is dominant species, using ethanol‐baited black cross‐vane traps, from March October over a 2‐year period (2023–2024). A total of 42 180 individuals including four genera and six species trapped, with Xyleborinus saxesenii (Ratzeburg) representing more than 90% all specimens. The other found included: Anisandrus dispar (F.), Xyleborus monographus Xylosandrus crassiusculus (Motschulsky) germanus (Blandford) . In addition these which already known be present surveyed area, maiche Kurentzov was collected for first time. Although recorded most cases did not raise particular concern among chestnut growers, strong increase their abundance 2024. Specifically, while have doubled presence, X. increased 10‐fold. Owing economic environmental value since beetles are significantly influenced by climatic factors, specific investigations needed time evaluate whether presence actually increasing, particularly context climate change.
