The little fire ant ( Wasmannia auropunctata ), notable for its minute size and painful sting, has emerged as a significant threat in Mediterranean Europe. This widespread exotic species is well-known because of invasive nature, impacting biodiversity, public health, economic activities.

Wasmannia auropunctata , also known as the ‘little fire ant’ or ‘electric ant’, is an invasive species that represents a serious threat to biodiversity and public health globally due its intrinsic characteristics low detectability. Here, through combination of morphological molecular identification, first record this in oceanic archipelago Canary Islands presented. Molecular data reveal population from completely different another established Málaga (mainland Spain), which suggests western Palearctic has been colonised at least two independent events. The early detection very limited area provides important temporal window for eradication prevention dispersal other areas.

Ants are an important arthropod group due to their involvement in ecological processes amongst others as ecosystem engineers or predators, but some invasive alien species also implicated detrimental environmental, economic and human health effects. Despite recent advancements, the ant biodiversity of Cyprus is still need further research with previous online inventories synthesising a checklist just 65 native 10 species. The “Ants Cyprus” website (https://sites.google.com/view/ants-of-cyprus) aims to: (1) raise public awareness increase local knowledge on significance ants, (2) provide data (3) enhance conservation efforts management practices for species, respectively. This dynamic, user-friendly has been designed use by scientific community, officers wider it will be regularly updated new information generated.

Invasive ants pose a risk to human well-being and social/ecosystem stability. Linepithema humile Mayr is among the most damaging invasive worldwide. Most L. populations invade ports/wharfs isolated from surrounding landscapes, but unfortunately, new population was discovered in an inland urban area (Nara Prefecture) of Japan 2021. In this study, first, supercolony type Nara identified via hostility test, then its distribution pattern characterized. aggression tests between four supercolonies (haplotypes LH1, LH2, LH3, LH4), ant showed extremely strong against all exept which detected only introduced range. Nara, abundant around river. Simulations revealed that using environment for movement/dispersal increased annual dispersal ability by 14 times compared with achieved ground (125 m), as mentioned literature. Therefore, river channels can serve major pathways long-distance invading areas. Since applying chemical strategies rivers problematic, preventing moving initial invasion sites crucial.
