Phoretic mite species

Table Description: The distribution and feeding behavior of mite species phoretic on Dendroctonus frontalis (SPB) in the United States. Generalist = feeds on multiple fungi, nematodes, and dead invertebrates. Mycetophagous = feeds on specific fungi, often transports and disperses reproductive structures of fungi. We categorize phoretic mites abundance on beetles as rare (< 1% of beetles have this species), Infrequent (1-5%), common (5-20%), and frequent (>20%). Mites identified by J.C. Moser and stored as voucher specimens by R. Hofstetter at Northern Arizona University.
