Tropilaelaps mites: a fast-spreading threat requiring urgent EU preparedness

The European beekeeping sector is no stranger to parasitic pressure. For decades, Varroa destructor has defined the baseline for colony health management. Attention is now also turning to Tropilaelaps, a parasite spreading westwards and nearing the European Union.
In a letter addressed to the European Commission, Member States, and National Reference Laboratories for bee health, BeeLife calls for immediate preparedness and reinforced vigilance, urging authorities to prevent the introduction of the mite and to effectively manage its potential spread.
A parasite characterised by rapid spread
Like Varroa, Tropilaelaps reproduces within capped brood cells of the honey bee, Apis mellifera. However, its biological characteristics make it particularly concerning:
faster reproductive rate;
rapid movement across combs;
exclusive feeding on brood;
very short phoretic phase.
These features enable infestations to develop quickly, potentially leading to rapid colony collapse.
Increasing proximity to the European Union
Tropilaelaps has already been detected in Georgia and in Russian regions bordering Ukraine, where it is associated with colony losses. According to the European Reference Laboratory for Bee Health, limitations in surveillance capacity in parts of the region make the epidemiological situation uncertain, while the risk of introduction into the EU remains significant.
Multiple pathways of introduction
The mite may enter the EU through several routes, including:
movement of live bees (particularly queens and packages)
used beekeeping equipment
apicultural products such as comb
This diversity of pathways increases the complexity of prevention and control.
No authorised treatments available
There are currently no veterinary medicinal products in the EU specifically authorised against Tropilaelaps. While some treatments used against Varroa destructor may offer partial efficacy, they do not provide a reliable or sustainable solution.
Preventive action, early detection, and rapid response therefore remain essential.
A limited window for action
Unlike Asian honey bee species, Apis mellifera has not evolved alongside Tropilaelaps, making European colonies particularly vulnerable.
If the mite becomes established, eradication would be extremely difficult. Experience with Varroa destructor demonstrates that delayed intervention leads to long-term, systemic impacts.
