Abstract:

Many arthropod species harbor a diverse range of viruses. While much is known about pathogenic viruses of some economically important insects and arthropods involved in disease transmission, viruses associated with mites have rarely been studied. The main objective of this study was to characterize the virome of Phytoseiulus persimilis (Phytoseiidae), a predatory mite commercially used worldwide for the biological control of the key pest Tetranychus urticae (Tetranichidae). A combination of de novo transcriptome assembly and virion sequencing, revealed that RNA viruses are highly prevalent and active tenants of commercial populations of P. persimilis, comprising on average 9% of the mite’s total mRNA. Seventeen RNA viruses dominated the mite’s virome (i.e., were highly transcribed) with over half (n = 10) belonging to the order Picornavirales, + ssRNA viruses that infect a large range of hosts, including arthropods. Screening of the 17 dominant virus sequences in P. persimilis and T. urticae revealed that three viruses (two Picornavirales of the families Iflaviridae and Dicistroviridae, and one unclassified Riboviria) are unique to P. persimilis and three others (two unclassified Picornavirales and one unclassified Riboviria) are present in both mite species. Most of the sequences were related to viruses previously documented in economically important arthropods, while others have rarely been documented before in arthropods. These findings demonstrate that P. persimilis, like many other arthropods, harbors a diverse RNA virome, which might affect the mite’s physiology and consequently its efficiency as a biological control agent.
