Aims: To evaluate the conformity of the results obtained by the European Union (EU) National Reference Laboratories (NRLs) for the identification of Tropilaelaps spp. by morphological examination

Modalities: Ring test consisting of sending a unique panel of samples, successively to each participating laboratory.

Requirements for participation: 

Due to logistical constraints, this comparative laboratory test (CLT) is only open to EU NRLs, which have not participated in the two previous campaigns.

NRLs from non-EU countries may also participate, depending on feasibility.

Comparative laboratory test (CLT) methods:

EURL procedure:  morphological identification of Tropilaelaps spp. (adult form)

This method is also published in the World Organisation for Animal Health (WOAH) Manual.

Matrix: Microscopic slides (specimens mounted in Hoyer medium).

Provisional Agenda:

Registration: January 2024

CLT period: From March to December 2024.
