Helicoverpa zea, commonly known as the corn earworm, is a species in the family Noctuidae. The larva of the moth Helicoverpa zea is a major agricultural pest. Since it is polyphagous during the larval stage, the species has been given many different common names, including the cotton bollworm and the tomato fruitworm. It also consumes a wide variety of other crops.
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.
The drugstore beetle, also known as the bread beetle, biscuit beetle, and misnamed as the biscuit weevil, is a tiny, brown beetle. It can be found infesting a wide variety of dried plant products, where it is among the most common non-weevils to be found. It is the only living member of the genus Stegobium. It belongs to the family Ptinidae, which also includes the deathwatch beetle and furniture beetle. A notable characteristic of this species is the symbiotic relationship the beetles have with the yeast they carry, which are transmitted from female to larvae through the oviduct.
The Indianmeal moth, also spelled Indian meal moth and Indian-meal moth, is a pyraloid moth of the family Pyralidae. Alternative common names are hanger-downers, weevil moth, pantry moth, flour moth or grain moth. The almond moth and the raisin moth are commonly confused with the Indian-meal moth due to similar food sources and appearance. The species was named for feeding on Indian meal or cornmeal, and does not occur natively in India. It is also not to be confused with the Mediterranean flour moth, another common pest of stored grains.
An allomone is a type of semiochemical produced and released by an individual of one species that affects the behaviour of a member of another species to the benefit of the originator but not the receiver. Production of allomones is a common form of defense against predators, particularly by plant species against insect herbivores. In addition to defense, allomones are also used by organisms to obtain their prey or to hinder any surrounding competitors.
The ant beetle, also known as the European red-bellied clerid, is a medium size insect, rather soft-bodied, with strong mandibles that can tear between the hard sclerotized integument of bark beetles. Larvae and adults are common predators of bark beetles in Europe.
Exomala orientalis, also known as the oriental beetle (OB), is a species of Rutelinae in the family of Scarabaeidae. It is a beetle about 0.7 - 1.1 cm long, with mottled, metallic brown- and black-colored elytra and a similarly colored thorax and head during the adult stage. It is sometimes confused with the larger and more colorful Japanese beetle. During the larval stage, the Oriental beetle can be identified by the parallel line raster pattern.
Mythimna unipuncta, the true armyworm moth, white-speck moth, common armyworm, or rice armyworm, is a species of moth in the family Noctuidae. The species was first described by Adrian Hardy Haworth in 1809. Mythimna unipuncta occurs in most of North America south of the Arctic, as well as parts of South America, Europe, Africa, and Asia. Although thought to be Neotropical in origin, it has been introduced elsewhere, and is often regarded as an agricultural pest. They are known as armyworms because the caterpillars move in lines as a massive group, like an army, from field to field, damaging crops.
The red flour beetle is a species of beetle in the family Tenebrionidae, the darkling beetles. It is a worldwide pest of stored products, particularly food grains, and a model organism for ethological and food safety research.
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.
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.
Agrilus biguttatus is a species of beetle in the family Buprestidae, the jewel beetles. Common names include oak splendour beetle, oak buprestid beetle, and two-spotted oak borer. It is native to Europe, North Africa, and Siberia. This beetle is known as a pest that causes damage to oak trees and is a factor in oak decline.
The common pine sawfly, Diprion pini, is a sawfly species in the family Diprionidae. It is a serious pest of economic forestry, capable of defoliating large areas of pine forest. It occurs throughout Europe and Russia.
Dendroctonus valens, also known as the red turpentine beetle, is a species of bark beetle characterized by a dark-reddish brown hue. It is native to forests across North and Central America. In its adult form, these beetles range from six to ten millimeters in length. A notable characteristic about them is their use of acoustic signals and chemical cues when engaging in what is a very complex mating process.
Dendroctonus terebrans, the black turpentine beetle, is a species of bark beetle native to the eastern United States. Its larvae tunnel under the bark of pine trees, weakening and sometimes killing the trees.
Ips confusus, known generally as the pinyon pine beetle or pinyon ips, is a species of typical bark beetle in the family Curculionidae. It is found in Central America and North America.
Ips avulsus, the small southern pine engraver, is a species of typical bark beetle in the family Curculionidae. The pheromones ipsenol, ipsdienol, and lanieron combined attract the most colonization in the host material in regards to the chemical ecology of the small southern pine engraver, which also effects their reproduction processes.
Dendroctonus adjunctus, the roundheaded pine beetle, is a species of bark beetle in the family Curculionidae found in North America. A parasite, the roundheaded pine beetle feeds on and eventually kills pine trees of several species in Guatemala, Mexico, and the Southern United States.
Cyrtophorus verrucosus, commonly known as the ant-like longhorn beetle or ant-mimic longhorn beetle, is a species of beetle in the family Cerambycidae. It is native to North America, more specifically southern Canada and the eastern United States.
