Analysis of recent interception records reveals frequent transport of arboreal ants and potential
predictors for ant invasion in Taiwan
In Taiwan, there were 439 interception records based on 8 years database. The intercepted ants
arrived predominantly via timber, a pattern likely reflecting the high domestic demand for foreign
timber in Taiwan. The most frequently intercepted species were either arboreal or wood-dwelling ants,
raising a concern of these ants constituting a next wave of ant invasion in Taiwan.
Consistent with other border interception databases, secondary introduction (i.e., species arriving from
their introduced ranges instead of their native ranges) also represents a major pathway for transport
of invasive ants into Taiwan, suggesting its role in shaping the global invasion of ants.
Invasive ants are commonly transported as hitchhikers or stowaways on human commerce. Their
long-distance spread also is frequently associated with human transportation, highlighting the
importance of incorporating pathway analysis in a risk assessment framework for invasive ants.
Intercepted ants originated from 31 different countries, with Vietnam being the most common
(contributing 29.2% of all interception records), followed by Japan, China, USA, Thailand, and Laos.
The most common commodity type on which ant species arrived into Taiwan was log/timber (46.7%).
For both Japan and the USA, log/timber was the most prevalent vector of exotic ants, whereas exotic
ants from China arrived predominantly on live plants.
Cr. Teranishii and the ghost ant Tapinoma melanocephalum were the most frequently intercepted
species from Japan and Thailand, respectively.
