| epitypification of ophiostoma galeiforme and phylogeny of species in the o. galeiforme complex. | ophiostoma galeiforme was described first in 1951 from larix kaempferi in scotland, where it was found to be associated with the bark beetles hy-lurgops palliatus, dryocoetes autographus, and the ambrosia beetle trypodendron lineatum. the taxonomy of this fungus has been uncertain because of a lack of sexual structures on the type specimen and contamination of a preserved ex-type culture. the aim of this study was to clarify application of the species name, o. galeiforme, by designating an epity ... | 2004 | 21148954 |
| nematode parasites and associates of dendroctonus spp. and trypodendron lineatum (coleoptera: scolytidae), with a description of bursaphelenchus varicauda n.sp. | nematode parasites and associates of four bark beetle species in british columbia were surveyed. bursaphelenchus varicauda n.sp., ektaphelenchus macrostylus, panagrolaimus dentatus, and cryptaphelenchus latus were found associated with dendroctonus pseudotsugae. parasitorhabditis obtusa was found in the gut and contortylenchus reversus in the hemocoel of both d. pseudotsugae and d. rufipennis. the latter also had hemocoel infections of sphaerulariopsis dendroetoni, which were not found concomita ... | 1983 | 19295808 |
| three genera in the ceratocystidaceae are the respective symbionts of three independent lineages of ambrosia beetles with large, complex mycangia. | the genus ambrosiella accommodates species of ceratocystidaceae (microascales) that are obligate, mutualistic symbionts of ambrosia beetles, but the genus appears to be polyphyletic and more diverse than previously recognized. in addition to ambrosiella xylebori, ambrosiella hartigii, ambrosiella beaveri, and ambrosiella roeperi, three new species of ambrosiella are described from the ambrosia beetle tribe xyleborini: ambrosiella nakashimae sp. nov. from xylosandrus amputatus, ambrosiella batrae ... | 2015 | 26466881 |
