FIRST RECORD OF THE MITE Histiostoma ulmi IN SILVER FIR AND INDICATION OF A POSSIBLE PHORETIC DISPERSAL BY THE LONGHORN BEETLE Acanthocinus reticulatus     pdf     HR     EN 599
Abstract:
The mite Histiostoma ulmi (Histiostomatidae), originally discovered by the describer within the bark beetle galleries of genus Scolytus, has been found to be phoretic on a tenebrionid beetle Hypophloeus bicolor. The first discovery of H. ulmi in the galleries of the longhorn beetle Acanthocinus reticulatus indicates the possibility of its phoretic association with several beetle carriers: tenebrionid, cerambycid and scolytid beetles. In Croatia, scolytids of the genus Pityokteines, occupying the same niche within their food plant, silver fir (Abies alba) could represent these additional carriers.
Acanthocinus reticulatus infested the bark of an Abies alba specimen as a pioneer taxon, as opposed to the usual earliest colonising beetles Pityokteines spinidens and P. curvidens. Histiostoma ulmi was reared from samples taken from the galleries of this longhorn beetle’s larvae. As is typical for histiostomids, these mites feed on bacteria. They represent a monophyletic group of at least six very similar species. The morphological characters separating H. ulmi from similar species are expressed only in adult mites. Deutonymphs found attached to Pityokteines were previously determined to be Histiostoma piceae, but were never reared to adulthood. Due to a close resemblance between the deutonymphs of H. piceae and H. ulmi, incorrect assignments, relying only on deutonymphs for determination, are possible. H. ulmi was observed under laboratory conditions carrying spores of an undetermined mold fungus. Other phoretic mites, such as Tarsonemus, are known to carry spores of blue stain fungi (Ophiostomatidae) which could be of practical importance in silver fir decline. Future studies need to show, whether deutonymphs of H. ulmi, possible vectored by bark beetles, tenebrionids and longhorn beetles, also carry spores of blue stain fungi.
