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.
A bark beetle is the common name for the subfamily of beetles Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be a specialized clade of the "true weevil" family (Curculionidae). Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many species with other lifestyles, including some that bore into wood, feed in fruit and seeds, or tunnel into herbaceous plants. Well-known species are members of the type genus Scolytus, namely the European elm bark beetle S. multistriatus and the large elm bark beetle S. scolytus, which like the American elm bark beetle Hylurgopinus rufipes, transmit Dutch elm disease fungi (Ophiostoma). The mountain pine beetle Dendroctonus ponderosae, southern pine beetle Dendroctonus frontalis, and their near relatives are major pests of conifer forests in North America. A similarly aggressive species in Europe is the spruce ips Ips typographus. A tiny bark beetle, the coffee berry borer, Hypothenemus hampei is a major pest on coffee plantations around the world.
Hypothenemus hampei, the coffee berry borer or coffee borer beetle, is a small beetle native to Africa. It is among the most harmful pests to coffee crops across the world where coffee is cultivated. Spanish common names of the insect include barrenador del café, gorgojo del café, and broca del café.
Tomicus piniperda, the common pine shoot beetle, is a bark beetle native throughout Europe, northwestern Africa, and northern Asia. It is one of the most destructive shoot-feeding species in northern Europe.
Xyleborus glabratus, the redbay ambrosia beetle, is a type of ambrosia beetle invasive in the United States. It has been documented as the primary vector of Raffaelea lauricola, the fungus that causes laurel wilt, a disease that can kill several North American tree species in the family Lauraceae, including redbay, sassafras, and avocado.
Forest pathology is the research of both biotic and abiotic maladies affecting the health of a forest ecosystem, primarily fungal pathogens and their insect vectors. It is a subfield of forestry and plant pathology.
Metaparasitylenchus hypothenemi is a free-living nematode parasite that infects coffee berry borers, small beetles that harm coffee crops worldwide. This nematode has been shown to interfere with the parasitic activity of the coffee berry borer by increasing the mortality of its progeny.
The European spruce bark beetle, is a species of beetle in the weevil subfamily Scolytinae, the bark beetles, and is found from Europe to Asia Minor and some parts of Africa.
Dendroctonus frontalis, the southern pine beetle, often shortened to simply SPB, is a species of bark beetle native to the forests of the southern United States, Mexico and Central America. It has recently expanded its range to the northeastern United States, where it is considered an invasive species and has destroyed massive amounts of pine forest.
Hylastes ater is a species of beetle in the family Curculionidae, the true weevils. It is a bark beetle, a member of the subfamily Scolytinae. Its common name is the black pine bark beetle. It is native to Europe and parts of Asia, including China and Korea. It is known as an introduced species in many other regions, including Australia, New Zealand, the Americas, and South Africa. It is a pest of pines and other trees, and it is widespread in areas where pine trees are cultivated. The species "is an important threat to the biosecurity of all forested countries."
Ips is a genus of beetles in the family Curculionidae, the true weevils. They are bark beetles, members of the subfamily Scolytinae. Species are distributed throughout the Northern Hemisphere. Some are known as introduced species in Australia and Africa. Many species are pests of forest trees, especially pines and spruces. They are known commonly as engraver beetles, ips engraver beetles, and pine engravers.
Naupactini is a tribe of broad-nosed weevils. Primarily from the Neotropical realm, reaches highest genus and species diversity in South America. Their size varies from 3.5 to 35 mm long, and its colour patterns are diverse. As well many has colourful iridescent scales, others show opaque scales or setae, and some are subglabrous. In habitats with sparse vegetation or trees absence, the occurrence of flightlessness and parthenogenesis is frequent.
Curculio elephas is a species of beetle in the family Curculionidae, the true weevils. It is known commonly as the chestnut weevil. It is a serious pest of chestnut in Europe.
Ophiostoma breviusculum is a species of fungus in the family Ophiostomataceae, associated with bark beetles infesting larch in Japan. It belongs in the Ophiostoma piceae complex. It was also found in insect galleries of Larix kaempferi. The length of its perithecial necks and synnemata are shorter than in O. piceae. The synnemata also differ from the latter morphologically.
Anaphes nitens is a species of fairyfly, a chalcid wasp in the family Mymaridae. Native to Australia, it is an egg parasitoid of the gum tree snout beetle, a pest of Eucalyptus trees, and has been used in biological pest control of that species.
Verbenol (2-pine-4-ol) is a group of stereoisomeric bicyclic monoterpene alcohols. These compounds have been found to be active components of insect pheromones and essential oils.
Listronotus oregonensis, the carrot weevil, is a species of weevil in the beetle family Curculionidae. It is found in North America.
Ips pini, known generally as the pine engraver or North American pine engraver, is a species of typical bark beetle in the family Curculionidae. Males construct nuptial chambers in the bark of dead pine or spruce trees. Ips pini is a tremendous pest when it comes to pines, but mostly of mature red pine plantations. When humans try to get rid of them by trying to burn their habitat, it makes them reproduce even more. As trees get wider, their population ends up competing with other species, but mostly because of the temperature and the chemicals used to stop them is helping the beetle even more.
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, Japan, the Korean peninsula and Mongolia.
Odoiporus longicollis, commonly known as banana stem weevil or banana pseudostem borer, is a species of weevil found in South Asia and South East Asia.
