Mosquito Coil
A mosquito coil is a mosquito-repelling incense, usually made into a spiral, and typically made using dried paste of pyrethrum powder. The coil is usually held at the center of the spiral, suspending it in the air, or wedged by two pieces of fireproof netting to allow continuous smoldering. Burning usually begins at the outer end of the spiral and progresses slowly toward the center of the spiral, producing a mosquito-repellent smoke. A typical mosquito coil measures around in diameter and lasts around seven to twelve hours. Mosquito coils are widely used in Asia, Africa, South America, Canada, Mexico and Australia. Invention Pyrethrum was used for centuries as an insecticide in Persia and Europe, being developed into a mosquito coil in the late 1800s by a Japanese couple: Yuki and Eiichiro Ueyama ( 上山英一郎). At that time in Japan, pyrethrum powder was mixed with sawdust and burned to repel mosquitoes. Ueyama initially created incense sticks mixed from starch powder, dr ...

Insect Repellents
An insect repellent (also commonly called "bug spray") is a substance applied to skin, clothing, or other surfaces to discourage insects (and arthropods in general) from landing or climbing on that surface. Insect repellents help prevent and control the outbreak of insect-borne (and other arthropod-bourne) diseases such as malaria, Lyme disease, dengue fever, bubonic plague, river blindness, and West Nile fever. Pest animals commonly serving as vectors for disease include insects such as flea, fly, and mosquito; and ticks (arachnids). Some insect repellents are insecticides (bug killers), but most simply discourage insects and send them flying or crawling away. Nearly any would be fatal upon reaching the median lethal dose, but classification as an insecticide implies death even at lower doses. Effectiveness Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents. For protection against mosquito bites, the U.S. Centers for Disease C ...

Incense
Incense is aromatic biotic material that releases fragrant smoke when burnt. The term is used for either the material or the aroma. Incense is used for aesthetic reasons, religious worship, aromatherapy, meditation, and ceremony. It may also be used as a simple deodorant or insect repellent. Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosquito Trap
Mosquito control manages the population of mosquitoes to reduce their damage to human health, economies, and enjoyment. Mosquito control is a vital public-health practice throughout the world and especially in the tropics because mosquitoes spread many diseases, such as malaria and the Zika virus. Mosquito-control operations are targeted against three different problems: # Nuisance mosquitoes bother people around homes or in parks and recreational areas; # Economically important mosquitoes reduce real estate values, adversely affect tourism and related business interests, or negatively impact livestock or poultry production; # Public health is the focus when mosquitoes are Vector (epidemiology), vectors, or transmitters, of infectious disease. Disease organisms transmitted by mosquitoes include West Nile virus, St. Louis Encephalitis, Saint Louis encephalitis virus, Eastern equine encephalomyelitis virus, Everglades virus, Highlands J virus, La Crosse Encephalitis virus in the ...

Particulates
Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM) or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the air. The term '' aerosol'' commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or anthropogenic. They have impacts on climate and precipitation that adversely affect human health, in ways additional to direct inhalation. Types of atmospheric particles include suspended particulate matter; thoracic and respirable particles; inhalable coarse particles, designated PM, which are coarse particles with a diameter of 10 micrometers (μm) or less; fine particles, designated PM, with a diameter of 2.5 μm or less; ultrafine particles, with a diameter of 100 nm or less; and soot. The IARC and WHO designate airborne particulates as a Group 1 carcinogen. Particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N-Octyl Bicycloheptene Dicarboximide
''N''-Octyl bicycloheptene dicarboximide (MGK 264) is an ingredient in some common pesticides. It has no intrinsic pesticidal qualities itself, but rather is a Synergy#Toxicological synergy, synergist enhancing the potency of pyrethroid ingredients. It is used in a variety of household and veterinary products. MGK 264 is starting to appear on pesticide monitoring lists by states legalizing and mandating pesticide monitoring in medical and recreational cannabis. This is most likely due to the very large amounts of pyrethrenoids that are used in cannabis monitoring lists and the likelihood of MGK 264 usage to maximize yield.

National Toxicology Program Chemical Repository Database. Research Triangle Park, North Carolina. organic compound used as a synergist component of pesticide formulations. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone. It is a semisynthetic derivative of safrole.Robert L. Metcalf "Insect Control" in Ullmann’s Encyclopedia of Industrial Chemistry" Wiley-VCH, Weinheim, 2002. History PBO was developed in the late 1930s and early 1940s to enhance the performance of the naturally derived insecticide pyrethrum. Pyrethrum is and was an important insecticide against mosquitoes and other disease-carrying vectors, thereby providing public health benefits, e.g., preventing malaria. Although exhibi ...

Butylated Hydroxytoluene
Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. BHT is widely used to prevent free radical-mediated oxidation in fluids (e.g. fuels, oils) and other materials, and the regulations overseen by the U.S. F.D.A.—which considers BHT to be " generally recognized as safe"—allow small amounts to be added to foods. Despite this, and the earlier determination by the National Cancer Institute that BHT was noncarcinogenic in an animal model, societal concerns over its broad use have been expressed. BHT has also been postulated as an antiviral drug, but as of December 2022 , use of BHT as a drug is not supported by the scientific literature and it has not been approved by any drug regulatory agency for use as an antiviral. Natural occurrence Phytoplankton, including the green algae ''Botryococcus braunii'', as well as three different cyanobacteria ...

Metofluthrin
Metofluthrin is a pyrethroid used as an insect repellent. The vapors of metofluthrin are highly effective and capable of repelling up to 97% of mosquitoes in field tests. Metofluthrin is used in a variety of consumer products, called emanators, for indoor and outdoor use. These products produce a vapor that protects an individual or area. Effectiveness is reduced by air movement. Metofluthrin is neurotoxic, and is not meant to be applied directly to human skin. Although metofluthrin has insecticidal properties against the sand fly, ''Phlebotomus sergenti'', it is not an effective repellent of this insect.
