The boll weevil is a species of beetle in the family Curculionidae. The boll weevil feeds on cotton buds and flowers. Thought to be native to Central Mexico, it migrated into the United States from Mexico in the late 19th century and had infested all U.S. cotton-growing areas by the 1920s, devastating the industry and the people working in the American South. During the late 20th century, it became a serious pest in South America as well. Since 1978, the Boll Weevil Eradication Program in the U.S. allowed full-scale cultivation to resume in many regions.
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than 6 mm in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
The Papaveraceae are an economically important family of about 42 genera and approximately 775 known species of flowering plants in the order Ranunculales, informally known as the poppy family. The family is cosmopolitan, occurring in temperate and subtropical climates, but almost unknown in the tropics. Most are herbaceous plants, but a few are shrubs and small trees. The family currently includes two groups that have been considered to be separate families: Fumariaceae and Pteridophyllaceae.
In physics, specifically field theory and particle physics, the Proca action describes a massive spin-1 field of mass m in Minkowski spacetime. The corresponding equation is a relativistic wave equation called the Proca equation. The Proca action and equation are named after Romanian physicist Alexandru Proca.
Corydalis is a genus of about 540 species of annual and perennial herbaceous plants in the family Papaveraceae, native to the temperate Northern Hemisphere and the high mountains of tropical eastern Africa. They are most diverse in China and the Himalayas, with at least 357 species in China.
The beetle subfamily Curculioninae is part of the weevil family Curculionidae. It contains over 23,500 described species in 2,200 genera, and is therefore the largest weevil subfamily. Given that the beetle order (Coleoptera) contains about one-quarter of all known organisms, the Curculioninae represent one of the – if not the – most successful radiations of terrestrial Metazoa.
Chamaerops is a genus of flowering plants in the family Arecaceae. It contains only one species, Chamaerops humilis, variously called European fan palm or the Mediterranean dwarf palm. It is one of the most cold-hardy palms and is used in landscaping in temperate climates.
Arenga pinnata is an economically important feather palm native to tropical Asia, from eastern India east to Malaysia, Indonesia, and the Philippines in the east. Common names include sugar palm, areng palm, black sugar palm, and kaong palm, among other names.
Diaprepes abbreviatus, also known as the diaprepes root weevil, citrus root weevil and sugarcane rootstock borer weevil, is a species of weevil that is native to the Caribbean, where in Spanish it is colloquially called chichí. It has become an invasive pest in several locations in the United States.
Brentidae, sometimes known as the primitive weevils, is a cosmopolitan family of primarily xylophagous beetles also known as straight-snouted weevils. The concept of this family has been expanded with the inclusion of three groups formerly placed in the Curculionidae; the subfamilies Apioninae, Cyladinae, and Nanophyinae, as well as the Ithycerinae, previously considered a separate family. They are most diverse in the tropics, but occur throughout the temperate regions of the world. They are among the families of weevils that have non-elbowed antennae, and tend to be elongate and flattened, though there are numerous exceptions.
Ynys-hir RSPB reserve is a nature reserve of the RSPB situated beside the Dyfi estuary in Ceredigion, mid Wales between Aberystwyth and Machynlleth. The reserve covers 550 hectares and includes a variety of habitats extending inland from mudflats and salt marsh through farmland and pools to oak woodland and hillside scrub. Facilities include a small visitor centre and seven hides.
Rhinotia hemisticta is a species of weevil in the family Belidae, commonly referred to as the long-nosed weevil, or long nosed weevil. It is found in Australia, is about 1 inch (2.5 cm) long, and is found in wooded areas.
Alexandru Proca was a Romanian physicist who studied and worked in France. He developed the vector meson theory of nuclear forces and the relativistic quantum field equations that bear his name for the massive, vector spin-1 mesons.
Lixus concavus, commonly called the rhubarb curculio, is a species of weevil. Rhubarb is a host, together with dock, sunflower, and thistle.
The maize weevil, known in the United States as the greater rice weevil, is a species of beetle in the family Curculionidae. It can be found in numerous tropical areas around the world, and in the United States, and is a major pest of maize. This species attacks both standing crops and stored cereal products, including wheat, rice, sorghum, oats, barley, rye, buckwheat, peas, and cottonseed. The maize weevil also infests other types of stored, processed cereal products such as pasta, cassava, and various coarse, milled grains. It has even been known to attack fruit while in storage, such as apples.
Ceratocapnos claviculata, the climbing corydalis, is a weak scrambling plant in the family Papaveraceae. It is endemic to Europe, growing mostly near the Atlantic fringe.
The biological screw joint is a naturally occurring form of the screw joint, a mechanical device that combines rotational movement with single-axis translation. Alexander Riedel of the State Museum of Natural History Karlsruhe and Thomas van de Kamp of the Karlsruhe Institute of Technology discovered it in specimens of Trigonopterus oblongus, a weevil found in Papua.
Weeleyhall Wood is a 31 hectare biological Site of Special Scientific Interest north of Clacton-on-Sea in Essex. It is managed by the Essex Wildlife Trust.
Procas lecontei is a species of marsh weevil in the beetle family Brachyceridae. It is found in North America.
Procas is a genus of marsh weevils in the family of beetles known as Brachyceridae. There are at least 20 described species in Procas.
