Nitidulidae trapping performed from 2018 to 2021 to characterize flight behaviors of potential vectors of the oak wilt pathogen yielded three new species records for Canada, six new species records for Ontario, and three new species records for Manitoba. The new records for Canada include Carpophilus (Ecnomorphus) corticinus reported from Ontario, C. (Myothorax) nepos reported from Ontario and Manitoba, and Glischrochilus (Librodor) obtusus reported from Ontario. In addition, the following species are first recorded in Ontario: Carpophilus (Ecnomorphus) antiquus, C. (Megacarpolus) sayi, Stelidota coenosa; and also in Manitoba: Carpophilus (Megacarpolus) lugubris and Cychramus adustus. Collection data is provided for the two provinces and national records.

Dead wood is an important habitat for both fungi and insects, two enormously diverse groups that contribute to forest biodiversity. Unlike the myriad of studies on fungus–insect relationships, insect communities on ascomycete sporocarps are less explored, particularly for those in hidden habitats such as underneath bark. Here, I present my observations of insect community dynamics on Biscogniauxia spp. on oak dead wood from the early anamorphic stage to matured teleomorph stage, aided by the debarking behaviour of squirrels probably targeting on these fungi. In total, 38 insect taxa were observed on Biscogniauxia spp. from March to November. The community composition was significantly correlated with the presence/absence of Biscogniauxia spp. Additionally, Librodor (Glischrochilus) ipsoides, Laemophloeus submonilis, and Neuroctenus castaneus were frequently recorded and closely associated with Biscogniauxia spp. along its change from anamorph to teleomorph. L. submonilis was positively associated with both the anamorph and teleomorph stages. L. ipsoides and N. castaneus were positively associated with only the teleomorph but not with the anamorph stage. N. castaneus reproduced and was found on Biscogniauxia spp. from June to November. These results suggest that sporocarps of Biscogniauxia spp. are important to these insect taxa, depending on their developmental stage.

The seasonal activity of Coleoptera was studied using fermental crown traps. The study was conducted from April to October 2019 in five forest biotopes (aspen, lime, pine, birch and oak) in the territory of the Mordovia State Nature Reserve (Russia, Republic of Mordovia). Eighty-three species are found from 31 families. Cerambycidae (13 species), Nitidulidae (11 species) and Curculionidae (9 species) had the greatest species diversity. A significant part of the identified taxa (57 species from 23 families) can be attributed to saproxylic beetles. The peak abundance of Coleoptera in four biotopes (aspen, lime, pine and birch forests) was in mid-May; in an oak forest, it was at the beginning of June. Seven species seasonal activity was monitored (Cryptarcha strigata, Glischrochilus hortensis, Glischrochilus grandis, Cychramus luteus, Soronia grisea, Protaetia marmorata and Anisandrus dispar).

Ovipositor as depicted in Fig. 11. Differential diagnosis. Glischrochilus ruzickai sp. nov. differs from all hitherto known Old World species of the subgenus Librodor in the following combination of characters: (i) pronotum with uniform punctation, (ii) posterior pronotal angles not projecting posteriad, (iii) pronotal base not bordered, (iv) each elytron black with three round orange spots, and (v) ventral surface and pygidium blackish brown to black. Border of the basal pronotal margin is either absent or indistinctly developed in several species of Glischrochilus from Asia: G. flavoguttatus (Reitter, 1875), G. flavipennis (Reitter, 1875), G. luteoniger Jelínek, 1982, G. mirabilis Jelínek, 1975, G. pantherinus (Reitter, 1879), G. pallidescriptus Jelínek, 1999. All these species differ from G. ruzickai sp. nov. in their colour pattern and other traits. Glischrochilus flavoguttatus from Himalaya also has black elytra, each with three round yellow spots, but differs in having red pronotum, shorter and bluntly pointed anterior pronotal angles as well as finer and sparser punctation of elytra. Its sutural line is distinct only in posterior half of elytra, whereas it reaches basal fourth of suture in G. ruzickai sp. nov. Colour pattern of G. ruzickai sp. nov. resembles that of G. parvipustulatus (Kolbe, 1886) and G. tibetanus Lasoń, 2016. However, both these species are as a rule much larger (body length 8.5–12.2 mm in G. tibetanus, 6.0– 10.8 mm in G. parvipustulatus), have distinctly bordered basal margin of pronotum, and pronotal punctures on sides markedly larger and closer. Etymology. Dedicated to our friend and one of the collectors of the new species, Jan Růžička (Prague, Czech Republic), a well-known specialist on Silphidae and Leiodidae; the specific epithet is a noun in the genitive singular. Collecting circumstances. At the type locality, the specimens were found sitting on sapping, freshly cut logs, lying in the hollow way through the secondary broadleaved forest (Fig. 12). Distribution. The species is known from south-western China (Sichuan and Yunnan provinces) and northern Myanmar., Published as part of Jelínek, Josef & Hájek, Jiří, 2018, Two new species of Glischrochilus with taxonomic comments, new records from Asia, and a world checklist of the genus (Coleoptera: Nitidulidae), pp. 567-576 in Acta Entomologica Musei Nationalis Pragae (Acta.

A new pheromon excreted by the Pine-bark beetle, Myelophilus piniperda L. (Col., Scolytidae). Experiments by help of olfactometres showed the females of M. piniperda excreting a pheromon which attracts males and females of the species. The effect of this pheromon is intensified by odorous substances excreted by the pine bark. The females of M. piniperda produce the hole of entrance and following the mating room in the bark. Then they send out their pheromon. Some species of predators (Glischrochilus quadripustulatus L., Thanasimus formicarius L. a.o.) are attracted by the pheromon too.

The paper presents information on four new and 16 locally distributed in the Baltic States coleopterous species from the Kaliningrad region. Such species as Reesa vespulae (Mill.), Pocadius adustus Reitt., Saulcyella schmidtii (Mark.) and Hypebaeus flavipes (F.) are reported for the eastern Baltic region for the first time. Other taxa – Elmis maugetii Latr., Georissus crenulatus (Rossi), Onthophagus Taurus (Schreber), Gnorimus nobilis (L.), Ovalisia rutilans (F.), Brachypterolus antirrhini (Murr.), Tetratoma ancora F., Aspidiphorus orbiculatus (Gyll.), Phryganophilus auritus Motsch., Metoecus paradoxus (L.), Glischrochilus grandis (Tourn.), Neomida haemorrhoidalis (F.), Phytoecia cylindrical (L.), Anidorus nigrinus (Germ.), Hispa atra L. and Psylliodes marcida (Ill.) are among locally and sporadically distributed in the Baltic States species. The current article also presents information on finding localities and date as well as ecological peculiarities of every species in the Kaliningrad region.

The saproxylic sap beetleGlischrochilus(Glischrochilus)quadripunctatus(Linnaeus, 1758), is associated with subcortical habitats of coniferous trees. This species is widely distributed across Europe and Siberia, and is the best known and largest European nitidulid species. A closely related cryptic species,G.(G.)tremulaesp. nov.has been discovered in a xerothermic area of SE Finland in association with old aspens. The two species exhibit a sympatric occurrence in SE Finland, on their respective host trees. We analyze the COI barcode region to compareG.(G.)quadripunctatus,G.(G.)tremulaesp. nov., andG. (Librodor) hortensis(Fourcroy, 1785). Morphological, ecological, and molecular data confirm the presence in SE Finland of twoGlischrochiluss.str. species. We provide a description of the new species. The newGlischrochilusapparently represents a relictual taxon associated with old hollow aspens, and should be considered a species with inherent conservation value within European saproxylic beetle communities.

The sap beetle, Colopterus truncatus (Coleoptera: Nitidulidae), is one of the primary vectors of the oak wilt pathogen, Ceratocystis fagacearum, in the north-central United States. Field behavioral assays utilizing various release rates and blends of three methyl-branched hydrocarbon aggregation pheromone components showed that flight responses of this beetle were similar in Illinois and Minnesota populations. In both locations, both sexes of the beetle responded synergistically to a combination of the three-component pheromone and fermenting whole-wheat bread dough. Further, Colopterus truncatus preferred a high release rate over a low release rate of the three-component blend. In both locations, the response of C. truncatus to a simplified version of the pheromone consisting of (2E,4E,6E)-3,5-dimethyl-2,4,6-octatriene (1) and (2E,4E,6E,8E)-3,5,7-trimethyl-2,4,6,8-decatetraene (3) was not significantly different from the response to the three-component blend. An experiment in Illinois with all possible combinations of the components demonstrated that the decatetraene (3) was the crucial component in the blend; of all treatments, the maximal response was elicited by 3 + dough. Chipped bark, phloem, and xylem from northern pin oak, Quercus ellipsoidalis, was not attractive to C. truncatus in Minnesota. During a weekly survey over two seasons in Minnesota, C. truncatus flew in response to the three-component pheromone between early April and early July, with the maximum responses coming on May 4, 2000 and April 20, 2001. During both years, more than 98% of the beetles were trapped between April 14 and June 1. During the same survey, Glischrochilus spp. (Nitidulidae) flew during longer periods of the summer, particularly in 2001. The sex ratio of C. truncatus responding during all experiments was female-biased (1.8:1, female–male), which is characteristic of other male-produced coleopteran aggregation pheromones. Other sap beetles that play a minor role in the pathobiology of C. fagacearum also responded in experiments conducted in Minnesota. Carpophilus brachypterus Say was cross-attracted to the two- and three-component blends of the C. truncatus pheromone and dough, whereas two Glischrochilus spp. were attracted to all treatments that contained dough.

Nitidulids are primary vectors of the oak wilt pathogen, Ceratocystis fagacearum (Bretz) Hunt, in the north-central United States. Species of adult nitidulids associated with different ages of oak wilt fungus mats on red oaks (Quercus rubra L. and Quercus ellipsoidalis E.J. Hill) during spring in east-central Minnesota were determined. The exoskeletal surfaces of representative specimens were assayed for the presence and abundance of the pathogen. Six species comprised 94% of 2542 adults, representing at least 12 species, collected between 1994 and 1996. Of these six species, Colopterus truncatus Randall and Epuraea corticina Erichson were the most abundant ones on immature mats (94% of 154 nitidulids). They were also more abundant than the other species on mature mats (77% of 868 nitidulids). Carpophilus sayi Parsons was the most common species (28% of 1134 nitidulids) on aging mats, while Carpophilus sayi and three Glischrochilus species (Glischrochilus sanguinolentus (Oliv.), Glischrochilus fasciatus (Oliv.), and Glischrochilus quadrisignatus Say) were predominant on declining mats (80% of 214 nitidulids). Multiple numbers of individuals of each species were commonly found on the mats. The smaller bodied species, C. truncatus and E. corticina, had the lowest numbers of fungal propagules on their bodies, while the highest incidence and numbers of viable propagules were found for the three largest bodied species (Glischrochilus spp.). These results are important to elucidating the principal nitidulid species involved in successful transmission of the pathogen in Minnesota.

The cosmopolitan genus Glischrochilus Reitter, 1873 (Nitidulidae: Cryptarchinae) is distributed in Holarctic and Oriental regions. According to the most recent catalogue (Jelinek & Audisio 2007), 32 species are known from the Palaearctic region. In China the genus is represented by 13 species, most of which were described by Jelinek (1975, 1982, 1999) and Lason (2009).

Egg production and mortality of six spp. of hibernating sap beetles (Coleoptera: Nitidulidae), Glischrochilus fasciatus (Olivier), G. quadrisignatus (Say), G. sanguinolentus (Olivier), Lobiopa undulata (Say), (Carpophilus brachypterus (Say), and Phenolia grossa (F.), were studied. Hibernating beetles captured in October oviposited under laboratory conditions without cold treatment. Pre-oviposition periods ranged from 0–14 weeks from date of capture. Five of six spp. maintained on apple laid eggs; the exception was G. sanguinolentus, which laid eggs when maintained on tomato. G. fasciatus and G. quadrisignatus exhibited significantly increased egg production on tomato, but also demonstrated significantly higher adult mortality than on apple.

Glischrochilus (Librodor) forcipatus (Fairmaire, 1889) has been known from the single holotype which could not be dissected, so that the status of the species remained doubtful. New specimens of G. forcipatus, recently collected after ca. 120 years, are redescribed and compared with related species G. (L.) japonius (Motschulsky, 1857), G. (L.) jelineki Lasoń, 2009 and G. (L.) parvipustulatus (Kolbe, 1886). Validity of G. forcipatus is confirmed and key for identification of the similar species is given.

New observations concerning the biology of the genus Hericia are provided, as well as a discussion of past observations from the literature. A new species, Hericia janehenleyi, is described and illustrated from adults, phoretic deutonymphs and non-phoretic deutonymphs collected from fermenting sap flux on oak trees (Quercus spp.) in eastern Virginia, U.S.A. Deutonymphs are phoretic on the sap flux inhabiting beetle Glischrochilus obtusus (Say) (Coleoptera, Nitidulidae).

The attraction of some bark- and ambrosia beetles as well as associated beetles to the host volatiles α-pinene and ethanol was studied in field tests with flight barrier traps. Tomicus piniperda (L.) (Scolytidae), Thanasimus formicarius (L.) (Cleridae), and Rhizophagus ferrugineus (Payk.) (Rhizophagidae) were attracted by α-pinene, while Hylurgops palliatus (Gyll.) and Trypodendron lineatum (Oliv.) (Scolytidae) were attracted by ethanol and Epuraea spp. (Nitidulidae) by both α-pinene and ethanol. Combinations of α-pinene and ethanol attracted high numbers of H. palliatus, T. lineatum, R. ferrugineus, Epuraea spp., and Glischrochilus spp. (Nitidulidae) and the catches increased with increasing release rates of ethanol. By contrast, lower numbers of T. piniperda were caught in traps baited with combinations of α-pinene and ethanol than in traps baited with α-pinene alone, and the catches of this species decreased with increasing release rates of ethanol. Traps baited with a combination of α-pinene and ethanol or with α-pinene alone caught similar numbers of T. formicarius. The results are discussed on the basis of species differences in preference for breeding substrate.

During the growing season of 1951 observations were made on the biology of the four-spotted fungus beetle, Glischrochilus q. quadringnatus (Say). Overwintering sites, emergence, mating, oviposition and larval habitats were observed. Simultaneous population estimates of adult beetles and of larvae of the European corn borer, Ostrinia nubilalis (Hubn.), were made in early sweet corn. Adult beetles of the first generation emerged and moved to corn fields coincident with the beginning of stalk invasion by half-grown borer larvae, Beetles congregated in borer tunnels and exerted a reductive effect on borer populations. This reduction was estimated at 17% of those larvae reaching the third instar or about 8% of the initial population. This reduction is believed to be caused by mechanical injury with subsequent direct attack on weakened or moribund larvae. Other species of the genus Glischrochilus have been reported as predators on eggs and larvae of various bark beetles in England and in the United States.

The following stucly is based on the material in the Canadian National Collection supplemented by specimens from the collections of Messrs. Carl G. Siepmann, F. S. Carr, and G. Stace Smith. No new characters for the separation of closely allied species are offered in this paper. The most valuable characters known are those of the so-called flagellum of the male genitalia; the most useful for key purposes are presented by the elytral markings.
