Abstract

. The phenology of fungal fruiting has changed in the UK over the last 70 years, but whether the associated mycophagous insects are able to exploit ‘out of season’ fruit bodies is unknown. This study focused on whether fungal baits can be used as a proxy to examine changes in fungal fruiting on insect communities. Using Agaricus bisporus as a bait, mushrooms were placed into two separate woodlands monthly from November 2020 to July 2021. Megaselia ru ﬁ pes (Phoridae) and Bradysia spp. (Sciaridae) were reared from both wild fungi and fungal baits at different times, making them appropriate species to consider for possible host tracking. Various factors affect an insect’s ability to track a fungal host, these include host preference, season, period of fungal fruiting and age of mushroom. Increased fruiting of macrofungi in the future may bene ﬁ t generalist mycophagous insects, by providing enhanced temporal and spatial resource opportunities. Using fungal baits as a proxy for the effects of climate change on fungal fruiting should be bene ﬁ cial in uncovering the host preferences of mycophagous insects and may potentially indicate whether mycophagous insects can track fungal hosts across seasons.

真菌昆虫群落的季节变化

．在过去的70年里，真菌结果的物候学在英国发生了变化，但相关的真菌昆虫是否能够利用“反季节”的果体尚不清楚。本研究的重点是真菌诱饵是否可以作为检测昆虫群落真菌结果变化的代理。从2020年11月到2021年7月，以双孢蘑菇为诱饵，每月在两个不同的林地中放置蘑菇。在不同时间用野生真菌和真菌饵料饲养大蝇蝇(Phoridae)和轻蝇蝇(Bradysia spp.)，使它们成为可能的寄主跟踪考虑的合适物种。影响昆虫追踪真菌寄主能力的因素有很多，包括寄主偏好、季节、真菌结果期和蘑菇年龄。未来大型真菌数量的增加可能会为多面手的真菌昆虫提供更多的时间和空间资源机会。利用真菌饵料作为气候变化对真菌结果的影响的代理，应该有助于揭示真菌寄生昆虫的寄主偏好，并可能潜在地表明真菌寄生昆虫是否可以跨季节跟踪真菌宿主。

期刊介绍： EJE publishes original articles, reviews and points of view on all aspects of entomology. There are no restrictions on geographic region or taxon (Myriapoda, Chelicerata and terrestrial Crustacea included). Comprehensive studies and comparative/experimental approaches are preferred and the following types of manuscripts will usually be declined: - Descriptive alpha-taxonomic studies unless the paper is markedly comprehensive/revisional taxonomically or regionally, and/or significantly improves our knowledge of comparative morphology, relationships or biogeography of the higher taxon concerned; - Other purely or predominantly descriptive or enumerative papers [such as (ultra)structural and functional details, life tables, host records, distributional records and faunistic surveys, compiled checklists, etc.] unless they are exceptionally comprehensive or concern data or taxa of particular entomological (e.g., phylogenetic) interest; - Papers evaluating the effect of chemicals (including pesticides, plant extracts, attractants or repellents, etc.), irradiation, pathogens, or dealing with other data of predominantly agro-economic impact without general entomological relevance.
