Ips Cembrae
''Ips cembrae'', known generally as larch bark beetle or eight-toothed larch bark beetle, is a species of typical bark beetle in the family Curculionidae. Its habitat is Euro-Siberian, ranging from sea level to sub-alpine. It was first recorded in Great Britain in 1955. Populations were said to be found in Japan and China, but further research determined that those were actually Ips subelongatus. The insect measures around 5 mm and has a dark brown to black colour. The species is considered hard to distinguish visually from Ips typographus. As a pest Ips cembrae is native to most of its habitat and is considered less of a pest risk than Ips typographus.EPPO/CABI 1997. Ips typographus. In: Quarantine pests for Europe, 2nd edn. Ed. by Smith IM, McNamara DG, Scott PR, Holderness M, CAB International, Wallingford. The beetle mainly affect the European larix, larix decidua, especially during periods of drought.

Curculionidae
The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae. They include the bark beetles as the subfamily Scolytinae, which are modified in shape in accordance with their wood-boring lifestyle. They do not much resemble other weevils, so they were traditionally considered a distinct family, Scolytidae. The family also includes the ambrosia beetles, of which the present-day subfamily Platypodinae was formerly considered the distinct family Platypodidae. Description Adult Curculionidae can be recognised by the well-developed, downwards-curved snout (rostrum) possessed by many species, though the rostrum is sometimes short (e.g. Entiminae). They have elbowed antennae that end in clubs, and the first antennal segment often fits into a groove in the side of the rostrum. The body tends to be robus ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Ips Subelongatus
''Ips subelongatus'', known generally as larch bark beetle or oblong bark beetle, is a species of typical bark beetle in the family Curculionidae. It is considered near indistinguishable from Ips cembrae except for the species of tree it chooses as a host and through DNA analysis. The species of tree it dwells in are ''Larix sibirica, Larix gmelinii, Larix leptolepis'' and ''Larix gmelinii'' var. ''olgensis''. The beetle is found in the Asian part of Russia, China (Heilongjiang, Jilin and Liaoning provinces), Japan (Hokkaido and Honshu), the Korean peninsula and Mongolia Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south.

Ips Typographus
The European spruce bark beetle (''Ips typographus''), is a species of beetle in the weevil subfamily bark beetle, Scolytinae, the bark beetles, and is found from Europe to Anatolia, Asia Minor and some parts of Africa. Biology of the species Morphology Adults are usually long, cylindrical and robust, black or brownish-black. Elytron, Elytral declivity is slightly shiny, with 4 teeth on each margin side. The third tooth is the biggest and club like on its top. The egg is yellowish-white. The larva is white and legless. The pupa is also white. Life cycle and interactions Bark beetles are so named because they reproduce in the inner bark, living and dead phloem tissues, of trees. Adult beetles hibernate in forest litter and host trees when environmental conditions are not favorable for reproduction. When conditions are right, they travel up to half a mile in search of a vulnerable host. Once the host is located, the adult burrows through the weakened Bark (botany), bark in ord ...

Larix Decidua
''Larix decidua'', the European larch, is a species of larch native to the mountains of central Europe, in the Alps and Carpathian Mountains as well as the Pyrenees, with disjunct lowland populations in northern Poland and southern Lithuania. It is widely naturalized in Scandinavia. Its life span has been confirmed to be close to 1000 years (with claims of up to 2000 years) but is more often around 200 years. It is claimed that one of the larches planted by the second Duke of Atholl at Dunkeld in 1738 is still standing. Description ''Larix decidua'' is a medium-size to large deciduous coniferous tree reaching 25–45 m tall, with a trunk up to 1 m diameter (exceptionally, to 53.8 m tall and 3.5 m diameter). The crown is conic when young, becoming broad with age; the main branches are level to upswept, with the side branches often pendulous. The shoots are dimorphic, with growth divided into long shoots (typically 10–50 cm long) and bearing several buds, and short shoots ...

Bursaphelenchus
__NOTOC__ ''Bursaphelenchus'' is a genus of nematodes (roundworms) in the order Aphelenchida. Most are obligate mycophages, but some feed on wood, with two species, the red ring nematode (''B. cocophilus'') and the pine wood nematode (''B. xylophilus''), economically significant as pests of coconut palms and of pine trees, respectively. Given that ''Bursaphelenchus'' species are usually hard to distinguish from one another except by trained nematologists with access to microscopes or DNA sequence analysis, the entire genus is put under quarantine in some countries. Where this is not the case however, these nematodes are becoming established as model organisms for nematode developmental biology, ecology and genetics. As of 2009, there are about 70 to 90 species in the genus. New taxa are described frequently. Ecology ''Bursaphelenchus'' contains a single described hermaphroditic species, ''okinawaensis'', and over 100 described gonochoristic species. They inhabit soil or decay ...

Frass
Frass refers loosely to the more or less solid excreta of insects, and to certain other related matter. Definition and etymology ''Frass'' is an informal term and accordingly it is variously used and variously defined. It is derived from the German word ''Fraß'', which means the food takeup of an animal.M. Clark and O. Thyen. The Oxford-Duden German Dictionary. Publisher: Oxford University Press 1999. The English usage applies to excreted residues of anything that insects had eaten, and similarly, to other chewed or mined refuse that insects leave behind. It does not generally refer to fluids such as honeydew, but the point does not generally arise, and is largely ignored in this article. Such usage in English originated in the mid-nineteenth century at the latest. Modern technical English sources differ on the precise definition, though there is little actual direct contradiction on the practical realities. One glossary from the early twentieth century speaks of "...excrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
