While little is known on ABAs of the red poultry mite (RPM), compared to ABAs of plant feeding mites, recent studies have identified potential ABAs for RPM. The poultry scientific community has yet to adopt the release and conservation of ABAs, partially because they lack the taxonomic expertise required to monitor the mite fauna before and after predator releases. Although the number of molecular taxonomy studies have increased substantially, species identification of mites is based almost entirely on morphology and is dependent on traditional taxonomists. Without reliable DNA barcodes for identification, and with only few mite taxonomists left for accurate morphological identification, we are clearly facing a taxonomic crisis. In the present study, we integrated molecular and morphological taxonomic tools with the aim of developing a library of mite DNA barcodes based on expertly identified specimens, to facilitate mite identification through DNA barcodes. Mites were collected from manure in poultry houses, bird nests, and from nearby soils. Series of isomorphic specimens were imaged, placed individually in micro-plates and sent to the Canadian Center for DNA barcoding for the sequencing. Following their return, mites were mounted on slides and 34 species were identified, belonging to the families (in parentheses no. of species per family) Laelapidae (4), Blattisociidae (3), Rhodacaridae (2), Digmasellidae (3), Melicharidae (3), Parasitidae (8), Macrochelidae (6), Ascidae (1) and Cheyletidae (4).
