Background:
Triatomines are hematophagous insects that act as vectors of Trypanosoma cruzi, the causative agent of Chagas disease. External Quality Assessment (EQA) is a tool used for monitoring and improving taxonomic identification activities performed by the health laboratories in Brazil.
Methods:
EQA were conducted in four municipalities in the state of Pernambuco. Boxes containing a panel of 12 adult Hemiptera specimens (male and female) were sent for species identification.
Results:
The results revealed 68% accuracy, with difficulty for morphologically similar species, such as those of the genus Rhodnius.
Conclusions:
EQA is essential for monitoring laboratory performance, highlighting the need for ongoing training.
