Lasioderma Serricorne
''Lasioderma serricorne'', commonly known as the cigarette beetle, cigar beetle, or tobacco beetle, is an insect very similar in appearance to the drugstore beetle (''Stegobium paniceum'') and the common furniture beetle (''Anobium punctatum''). All three species belong to the family Ptinidae. ''L. serricorne'' is around 2–3 mm long, and brown in colour. The beetles, which can fly, live 2–6 weeks and do not feed as adults. They can be distinguished from ''A. punctatum'' by the fact that ''A. punctatum'' has a thorax with a pronounced "humped" shape. ''S. paniceum'' and ''L. serricorne'' have thoraces which have a much less obtuse looking angle when viewed from the side compared to ''A. punctatum'', and thus could be difficult to tell apart. However ''S. paniceum'' has a distinct three-segmented "club" at the end of each antenna whereas ''L. serricorne'' has uniformly serrated antennae of 11 segments. ''L. serricorne'' also has much weaker punctures on the surface of the wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Norwell, Massachusetts
Norwell is a town in Plymouth County, Massachusetts, Plymouth County, Massachusetts, United States. The population was 11,351 at the 2020 United States census. The town's southeastern border runs along the North River (Massachusetts Bay), North River. History Norwell was first settled in 1634 as a part of the settlement of Satuit (later Scituate, Massachusetts, Scituate), which encompassed present-day Scituate and Norwell. It was officially created in 1849 and soon became known as South Scituate. The town changed its name by ballot to Norwell in 1888, after Henry Norwell, a dry goods merchant who provided funds for the maintenance of the town roads. Early settlers were attracted to Norwell for agricultural reasons, with the town later developing a major shipbuilding industry, based on the North and Northwest rivers. Shipbuilding was a major industry in the 18th through the early 19th centuries. Some of the finest frigates, schooners, whalers, and merchant vessels were produced in ...

Cypermethrin
Cypermethrin (CP) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces. Exposure to sunlight, water and oxygen will accelerate its decomposition. Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticides Telecommunications Network (NPTN). It is found in many household ant and cockroach killers, including Raid, Ortho, Combat, ant chalk, and some products of Baygon in Southeast Asia. Uses Cypermethrin is used in agriculture to control ectoparasites which infest cattle, sheep, and poultry. Human exposure Cypermethrin is moderately toxic through skin contact or ingestion. It may cause irritation to the skin and eyes. Symptoms of dermal exposure include numbness, tingling, itching, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphine
Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula , classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (). With traces of present, is spontaneously flammable in air ( pyrophoric), burning with a luminous flame. Phosphine is a highly toxic respiratory poison, and is immediately dangerous to life or health at 50 ppm. Phosphine has a trigonal pyramidal structure. Phosphines are compounds that include and the organophosphines, which are derived from by substituting one or more hydrogen atoms with organic groups. They have the general formula . Phosphanes are saturated phosphorus hydrides of the form , such as triphosphane. Phosphine, PH3, is the smallest of the phosphines and the smallest of the phosphanes.

Methyl Bromide
Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. It has a tetrahedral shape and it is a recognized ozone-depleting chemical. It was used extensively as a pesticide until being phased out by most countries in the early 2000s. Occurrence and manufacture Bromomethane originates from both natural and human sources. In the ocean, marine organisms are estimated to produce 56,000 tonnes annually. It is also produced in small quantities by certain terrestrial plants, such as members of the family Brassicaceae. It is manufactured for agricultural and industrial use by treating methanol with bromine in the presence of sulfur or hydrogen sulfide: :6 CH3OH + 3 Br2 + S → 6 CH3Br + 2 H2O + H2SO4 Uses In 1999, an estimated 71,500 tonnes of synthetic methyl bromide were used annually worldwide. 97% of this estimate was used for fumigation purposes, w ...

Pheromones
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). Pheromones ...

Cigarillo
A cigarillo (from Spanish ''cigarrillo'', meaning "cigarette", in turn from ''cigarro'' ("cigar") + ''-illo'' (diminutive suffix), pronounced in parts of Latin America or in Spain) is a short, narrow cigar. Unlike cigarettes, cigarillos are wrapped in tobacco leaves or brown, tobacco-based paper. Cigarillos are smaller than regular cigars but usually larger than cigarettes. Cigarillos are usually made without filters, and are meant to be smoked like a cigar and not inhaled (except those made in this form only for specific tax issues). Generally, a cigarillo contains about three grams of tobacco; the length varies from and the diameter is about 6–9 mm, usually 8 mm. Comparatively, a cigarette contains less than one gram of tobacco and is about in length and 8 mm in diameter. Most cigarillos are machine-made, which is cheaper than hand-rolling. It is unusual to store them in humidors, partly because they are smoked in large quantities and so have a short s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cigar
A cigar is a rolled bundle of dried and fermented tobacco leaves made to be smoked. Cigars are produced in a variety of sizes and shapes. Since the 20th century, almost all cigars are made of three distinct components: the filler, the binder leaf which holds the filler together, and a wrapper leaf, which is often the highest quality leaf used. Often there will be a cigar band printed with the cigar manufacturer's logo. Modern cigars often come with two bands, especially Cuban cigar bands, showing Limited Edition (''Edición Limitada'') bands displaying the year of production. Cigar tobacco is grown in significant quantities primarily in Central America and the islands of the Caribbean, including Cuba, the Dominican Republic, Haiti, Honduras, Mexico, Ecuador, Nicaragua, Guatemala, Costa Rica, Panama, and Puerto Rico; it is also produced in the Eastern United States, Brazil and in the Mediterranean countries of Italy and Spain (in the Canary Islands), and in Indonesia and the P ...

Tobacco Leaves
Tobacco is the common name of several plants in the genus ''Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word ''tobacco'' originates from the Spanish word "tabaco".
