  abstract = {{I}nvasive species are a major concern for the maintenance of ecosystem services and biodiversity but are difficult to mitigate. {U}pstream solutions to prevent their impact, including their detection, are needed. {W}asmannia auropunctata, an invasive ant living in vagile supercolonies, is especially hard to track and is a major threat for tropical ecosystems and local animal communities. {A}s part of such tropical communities, crickets are sensitive to ecological conditions, easy to collect, detectable and identifiable through their species-specific calls. {H}ere, we evaluated the use of an acoustic community of crickets as an indicator of the presence of {W}. auropunctata in {N}ew {C}aledonia. {W}e evaluated the dominance of the crickets in the soundscape, describe the cricket community structure and diversity along a shrubland to forest gradient, characterize these cricket communities structure and diversity in the light of ongoing invasion by {W}. auropunctata, and identify cricket species' indicators of the invasion. {A}coustic recordings collected on 24 sites were described using humanlistening and spectrographic visualization. {T}he results demonstrated a clear dominance of the cricket group in the {N}ew {C}aledonian nocturnal soundscapes. {E}ach habitat harbored a specific acoustic cricket community related to specific environmental attributes including vegetation height, daily variation of humidity and temperature. {T}he presence of {W}. auropunctata was significantly associated with a lower cricket acoustic activity and species richness at night. {O}f the 19 species detected, four nocturnal species were identified as indicator of non-invaded forests and preforests. {T}his work supports the use of acoustic as an alternative method to detect invasion.},
