Cucujidae
The Cucujidae, "flat bark beetles," are a family of distinctively flat beetles found worldwide (except Africa and Antarctica) under the bark of dead trees. The family has received considerable taxonomic attention in recent years and now consists of 70 species distributed in five genera. It was indicated Cucujus species are scavengers, only feeding on pupae and larvae of other insects and on other subcortical beetles such as their own. Since the Cucujidae prey on larvae of potentially tree damaging beetles that spread fungal diseases, they are considered to be beneficial to the health of living trees. Included genera are: ''Cucujus'' Fabricius, with 14 species and subspecies distributed throughout the Holarctic; ''Palaestes'' Perty, 8 spp., Neotropical; ''Pediacus'' Shuckard, 31 spp., mostly Holarctic, but extending south into the Neotropics and to Australia; ''Platisus'' Erichson, 5 spp. in Australia and New Zealand, and ''Thesaurus'' known from South America.

Cucujus
''Cucujus'' is a genus of beetles in the family Cucujidae, the flat bark beetles. It contains 19 currently recognized species and subspecies. Description Species of ''Cucujus'' are of moderate size (6-25mm), greatly dorso-ventrally compressed, and brightly colored, often red or red and black. Additionally, they can distinguished from other members of the family by the head being generally wider than the pronotum with prominent temples, and the elongate, inverted male genitalia with a flagellum. The genus occurs throughout the Holarctic The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical reg ... region, with indigenous species in North America, Europe, and Asia. It is most diverse in Asia.

Palaestes
''Palaestes'' is a genus of beetles in the family Cucujidae. It contains eight currently recognized species. Like all members of the Cucujidae, adults are greatly dorso-ventrally compressed. All known species of ''Palaestes'' are brightly colored red or yellow and black, and the males have curiously modified mandibles that look like ice tongs; female mandibles are not modified. ''Palaestes'' shares with the Australian-New Zealand genus '' Platisus'' the character of the male genitalia, which lacks a flagellum, lying on its side in the abdomen, versus inverted in ''Cucujus'' and ''Pediacus ''Pediacus'' is the largest genus in the family Cucujidae of flat bark beetles.

Cucujus Cinnaberinus
Larva of Cucujus cinnaberinus ''Cucujus cinnaberinus'' is a species of beetles in the family Cucujidae, the flat bark beetles. It is native to Europe, being most common in Central Europe and rare in much of Southern and Western Europe. This beetle lives under tree bark. It is associated with oaks (''Quercus'' spp.), maples (''Acer'' spp.), and poplars (''Populus'' spp.). It can be found in various habitat types, including forests and urban areas. It is a saproxylic species, often feeding on decomposing wood. It has also been observed eating maggots and the larvae of other beetles. This beetle is on the IUCN Red List as a near-threatened species. It is on many national lists of threatened species in Europe. Forest management practices include the removal of dead wood and dying trees, reducing available habitat and food sources for the beetle.Horak, J., Vávrová, E., & Chobot, K.

Pediacus
''Pediacus'' is the largest genus in the family Cucujidae of flat bark beetles. It contains 31 currently recognized species.Michael C. Thomas. 2004. A revision of ''Pediacus'' Shuckard (Coleoptera: Cucujidae) for America north of Mexico, with notes on other species. Insecta Mundi 17: 157-177 (2003). ''Pediacus'' adults are relatively small (2.7-7.0mm), flattened brownish beetles with no or very small temples, and short antennae with a distinct club. Male genitalia are inverted and possess a short flagellum. The genus is Holarctic in distribution, but extends south as far as Guatemala in the Western Hemisphere, generally at high altitudes, and into Australia in the Eastern Hemisphere. Adults and larvae are found under dead bark; frequently that of conifers in North America. They are thought to be predaceous.

Laemophloeidae
Laemophloeidae, "lined flat bark beetles," is a family in the superfamily Cucujoidea characterized by predominantly dorso-ventrally compressed bodies, head and pronotal discs bordered by ridges or grooves, and inverted male genitalia. Size range of adults is in length. Currently, it contains 40 genera and about 450 species, and is represented on all continents except Antarctica; species richness is greatest in the tropics. Classicification Historically, Laemophloeidae was treated as a subfamily of Cucujidae, but starting in the middle of the 20th century, most of what had been treated as subfamilies of the Cucujidae were considered to be families. Habitat and behaviour Most laemophloeids, adults and larvae, are found under bark of dead trees, where they apparently are primarily fungivores, although some genera with adults having subcylindrical bodies (e.g., '' Leptophloeus'', '' Dysmerus'') occur in the galleries of bark beetles (Curculionidae The Curculionidae are a family ...

Upis Ceramboides
''Upis ceramboides'' is a species of beetle, one of many wood-living insects that benefit from forest fires. It often occurs in quantities below the bark on the fire-damaged birches, but can sometimes be seen on other deciduous trees such as willow and aspen. The larvae thrive in the inner bark which is rich in mycelia, and in the sapwood. They develop into pupae during the summer months under the bark, and they develop over two or three years. The following spring they reproduce themselves. It has over the years have disappeared from southern Sweden and is now only locally in the Norrland coast (Västerbotten and Norrbotten) as well as Canada and Alaska. The reason for the species' decline is probably the lack of fire-damaged forests and birch, and the modern forestry practices. ''Upis ceramboides'' is considered "vulnerable" in terms of species survival. In Vindeln municipality it is called ', because it occurs indoors when burning firewood in winter. The species' survival at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xylomannan
Xylomannan is an antifreeze molecule, found in the freeze-tolerant Alaskan beetle ''Upis ceramboides''. Unlike antifreeze proteins, xylomannan is not a protein. Instead, it is a combination of a sugar (saccharide) and a fatty acid that is found in cell membranes. As such is expected to work in a different manner than AFPs. It is believed to work by incorporating itself directly into the cell membrane and preventing the freezing of water molecules within the cell. Xylomannan is also found in the red seaweed '' Nothogenia fastigiata'' ( Scinaiaceae family). Fraction F6 of a sulphated xylomannan from ''Nothogenia fastigiata'' was found to inhibit replication of a variety of viruses, including Herpes simplex virus types 1 and 2 (HSV-1, HSV-2), Human cytomegalovirus (HCMV, HHV-5), Respiratory syncytial virus (RSV), Influenzavirus A, Influenzavirus B, Junin and Tacaribe virus, Simian immunodeficiency virus, and (weakly) Human immunodeficiency virus The human immunodeficiency ...
