Clothianidin
Clothianidin is an insecticide developed by Takeda Chemical Industries and Bayer AG. Similar to thiamethoxam and imidacloprid, it is a neonicotinoid. Neonicotinoids are a class of insecticides that are chemically similar to nicotine, which has been used as a pesticide since the late 1700s. Clothianidin and other neonicotinoids act on the central nervous system of insects as an agonist of nAChR, the same receptor as acetylcholine, the neurotransmitter that stimulates and activating post-synaptic acetylcholine receptors but not inhibiting AChE. Clothianidin and other neonicotinoids were developed to last longer than nicotine, which is more toxic and which breaks down too quickly in the environment. However, studies published in 2012 show that neonicotinoid dust released at planting time may persist in nearby fields for several years and be taken up into non-target plants, which are then foraged by bees and other insects. Clothianidin is an alternative to organophosphate, carbamate, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neonicotinoid
Neonicotinoids (sometimes shortened to neonics ) are a class of neuro-active insecticides chemically similar to nicotine, developed by scientists at Shell and Bayer in the 1980s. The neonicotinoid family includes acetamiprid, clothianidin, dinotefuran, imidacloprid, nitenpyram, nithiazine, thiacloprid and thiamethoxam. Imidacloprid has been the most widely used insecticide in the world from 1999 through . Compared to organophosphate and carbamate insecticides, neonicotinoids are less toxic to birds and mammals. Neonicotinoid use has been studied in relation to adverse ecological effects, including honey-bee colony collapse disorder (CCD), and declining populations of insect-eating birds. In 2013, the European Union and some neighbouring countries restricted the use of certain neonicotinoids. In 2018 the EU banned the three main neonicotinoids (clothianidin, imidacloprid and thiamethoxam) for all outdoor uses, but in 2020, France re-allowed the use of neonicotinoids on sugar beet ...

Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellent ...

Indoor Residual Spraying
Indoor residual spraying or IRS is the process of spraying the inside of dwellings with an insecticide to kill mosquitoes that spread malaria. A dilute solution of insecticide is sprayed on the inside walls of certain types of dwellings—those with walls made from porous materials such as mud or wood but not plaster as in city dwellings. Mosquitoes are killed or repelled by the spray, preventing the transmission of the disease. In 2008, 44 countries employed IRS as a malaria control strategy. Several pesticides have historically been used for IRS, the first and most well-known being DDT. World Health Organization recommendations The World Health Organization (WHO) recommends IRS as one of three primary means of malaria control, the others being use of insecticide treated bednets (ITNs) and prompt treatment of confirmed cases with artemisinin-based combination therapies (ACTs). While previously the WHO had recommended IRS only in areas of sporadic malaria transmission, in 2006 it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed Treatment
In agriculture and horticulture, a seed treatment is any additional material added to the seed. By the amount of material added, it can be divided into: * A seed dressing, typically containing a "protectant" (pesticide) applied to the seed and possibly some color. * A seed coating, a layer of thin film applied to the seed typically less than 10% of the mass of the original seed. * Seed encrusting, where the applied material is typically 100%–500% of the original seed mass, but the shape is still discernible. * Seed pelleting, where the applied material is so thick that the seed's original shape is not discernible. Seed treatment provides the following functions: * For formulations with pesticides, direct application to seeds can be environmentally more friendly, as the amounts used can be very small. * Color makes treated seed less attractive to birds, and easier to see and clean up in the case of an accidental spillage. * A thick coating can improve handling, by hand or by ...

Bobwhite Quail
The northern bobwhite (''Colinus virginianus''), also known as the Virginia quail or (in its home range) bobwhite quail, is a ground-dwelling bird native to Canada, the United States, Mexico, and Cuba, with introduced populations elsewhere in the Caribbean, Europe, and Asia. It is a member of the group of species known as New World quail (Odontophoridae). They were initially placed with the Old World quail in the pheasant family ( Phasianidae), but are not particularly closely related. The name "bobwhite" is an onomatopoeic derivation from its characteristic whistling call. Despite its secretive nature, the northern bobwhite is one of the most familiar quails in eastern North America, because it is frequently the only quail in its range. Habitat degradation has likely contributed to the northern bobwhite population in eastern North America declining by roughly 85% from 1966 to 2014. This population decline is apparently range-wide and continuing. There are 23 subspecies of nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquatic Toxicity
Aquatic toxicology is the study of the effects of manufactured chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems. Aquatic toxicology is a multidisciplinary field which integrates toxicology, aquatic ecology and aquatic chemistry. This field of study includes freshwater, marine water and sediment environments. Common tests include standardized acute and chronic toxicity tests lasting 24–96 hours (acute test) to 7 days or more (chronic tests). These tests measure endpoints such as survival, growth, reproduction, that are measured at each concentration in a gradient, along with a control test. Typically using selected organisms with ecologically relevant sensitivity to toxicants and a well-established literature background. These organisms can be easily acquired or cultured in lab and are easy to handle. History While basic resear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pest Management Regulatory Agency
The Pest Management Regulatory Agency (PMRA) is the Canadian government agency responsible for the regulation of pest control products in Canada under the federal authority of the '' Pest Control Products Act'' and Regulations. The agency is a branch that reports to Parliament through Health Canada. The PMRA is responsible for providing access to pest management tools while minimizing the risks to human health and the environment by “using modern evidence-based scientific approaches to pesticide regulation, in an open and transparent manner”. Their main activity areas include: new product evaluation, post market review and compliance and enforcement. The PMRA works with provincial, territorial and federal departments in Canada to help refine and strengthen pesticide regulation across the country. Outside of Canada, the Agency works closely with international organizations such as the United States Environmental Protection Agency (EPA), the North American Free Trade Agreement ...

Toxicity
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell ( cytotoxicity) or an organ such as the liver (hepatotoxicity). By extension, the word may be metaphorically used to describe toxic effects on larger and more complex groups, such as the family unit or society at large. Sometimes the word is more or less synonymous with poisoning in everyday usage. A central concept of toxicology is that the effects of a toxicant are dose-dependent; even water can lead to water intoxication when taken in too high a dose, whereas for even a very toxic substance such as snake venom there is a dose below which there is no detectable toxic effect. Toxicity is species-specific, making cross-species analysis problematic. Newer paradigms and metrics are evolving to bypas ...

Pollinators
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most families of aculeate wasps; ants; many families of flies; many lepidopterans (both butterflies and moths); and many families of beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination. A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process. Background Plants fall into pollination syndromes that reflect the type of ...

Bee Keepers
Beekeeping (or apiculture) is the maintenance of bee colonies, commonly in man-made beehives. Honey bees in the genus '' Apis'' are the most-commonly-kept species but other honey-producing bees such as ''Melipona'' stingless bees are also kept. Beekeepers (or apiarists) keep bees to collect honey and other products of the hive: beeswax, propolis, bee pollen, and royal jelly. Pollination of crops, raising queens, and production of package bees for sale are other sources of beekeeping income. Bee hives are kept in an apiary or "bee yard". The keeping of bees by humans, primarily for honey production, began around 10,000 years ago. Georgia is known as the "cradle of beekeeping" and the oldest honey ever found comes from that country. The 5,500-year-old honey was unearthed from the grave of a noblewoman during archaeological excavations in 2003 near the town Borjomi. Ceramic jars found in the grave contained several types of honey, including linden and flower honey. Domestication of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
