Abstract

The predatory mites belong to Phytoseiidae family are effective biological control agents that feed on spider mites and some small pests. Their accurate identification is critical for success of biological control. The commonly used method for identification of phytoseiid species is confront of their morphologic features. As they are microscopic organisms with complex and minute taxonomic characters, various target DNA fragments including 12S rRNA, COI mtDNA, CytB mtDNA, and ITSS were identified as alternative diagnostic tools at the species level within a barcoding framework. In this study, we focus on the latest researches on the molecular barcoding of Phytoseiidae species found in Turkey. DNA sequence data in this review have been obtained from NCBI GENBANK database. The DNA sequences shared in the database was mostly produced by using COI mtDNA marker and followed by 12S rRNA, ITSS, CytB mtDNA and HSP90, respectively. Among 112 phytoseiid species recorded from Turkiye, 45% of them have already been characterized by molecular identification while 55% of which still need to be sequenced. Based on the DNA sequences belonging to species from 23 different genera, Typhlodromus is the most studied genera, and followed by Neoseiulus, Amblyseius, Euseius, and Phytoseiulus. Although Typhlodromus pyri is not predominant in Turkiye, this species is the most sequenced species among 30 different species in the genus Typhlodromus. Considering ecological and habitat variations, present molecular data about Turkish phytoseiid populations is inadequate. In the future, it is necessary to perform more molecular studies covering both Turkish populations and undefined worldwide species.
