Dermanyssus Gallinae
''Dermanyssus gallinae'' (also known as the red mite) is a haematophagous ectoparasite of poultry. It has been implicated as a vector of several major pathogenic diseases. Despite its common names, it has a wide range of hosts including several species of wild birds and mammals, including humans, where the condition it causes is called gamasoidosis. In both size and appearance, it resembles the northern fowl mite, '' Ornithonyssus sylviarum.'' Description ''Dermanyssus gallinae'' is an obligate blood feeder that will normally attack its host at night, but will occasionally feed during the day. Adults are long, with long legs and usually a grayish-white body, which becomes reddish-brown when engorged. After feeding, they hide in cracks and crevices away from light sources, where they mate and lay eggs. Mites progress through five life stages: egg, larva, protonymph, deutonymph and adult. Under favourable conditions this life cycle can be completed within seven days, so pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles De Geer
Charles De Geer (30 January 1720 – 7 March 1778) was an entomology, entomologist, industrialist, civil servant and book collecting, book collector. He is sometimes referred to as Charles the Entomologist, to distinguish him from other relatives with the same name. Charles De Geer came from a prominent Swedish-Dutch family. Born in Sweden, he spent most of his childhood and youth in the Dutch Republic. At the age of 18 he moved back to Sweden and would spend the rest of his life there. Upon his return to Sweden, he took over the management of the ironworks of Lövstabruk. He was a successful businessman and with time became one of the richest men in Sweden, head of an early industry employing around 3,000 people. He had a successful civic career, became Marshal of the Court (Sweden), Marshal of the Court and was elevated to the rank of ''Freiherr#Swedish_and_Danish–Norwegian_title, friherre'' (baron) in 1773. De Geer had developed an interest in natural history and particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wound Healing
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events is set into motion to repair the damage. This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth ( cell proliferation), and tissue remodeling (maturation and cell differentiation). Blood clotting may be considered to be part of the inflammation stage instead of a separate stage. The wound-healing process is not only complex but fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes, venous or arterial disease, infection, and metabolic deficiencies of old age.Enoch, ...

Organophosphate Insecticide
In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure , a central phosphate molecule with alkyl or aromatic substituents. They can be considered as esters of phosphoric acid. Organophosphates are best known for their use as pesticides. Like most functional groups, organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, nerve agents and flame retardants. OPEs have been widely used in various products as flame retardants, plasticizers, and performance additives to engine oil. The low cost of production and compatibility to diverse polymers made OPEs to be widely used in industry including textile, furniture, electronics as plasticizers and flame retardants. These compounds are added to the final product physically rather than by chemical bond. Due to this, OPEs leak into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acaricide Resistance
Pesticide resistance describes the decreased susceptibility of a pest population to a pesticide that was previously effective at controlling the pest. Pest species evolve pesticide resistance via natural selection: the most resistant specimens survive and pass on their acquired heritable changes traits to their offspring.PBS (2001)Pesticide resistance Retrieved on September 15, 2007. If a pest has ''resistance'' then that will reduce the pesticide's ''efficacy'' efficacy and resistance are inversely related. Cases of resistance have been reported in all classes of pests (''i.e.'' crop diseases, weeds, rodents, ''etc.''), with 'crises' in insect control occurring early-on after the introduction of pesticide use in the 20th century. The Insecticide Resistance Action Committee (IRAC) definition of insecticide resistance is ''a heritable change in the sensitivity of a pest population that is reflected in the repeated failure of a product to achieve the expected level of control whe ...

Ectoparasiticide
An ectoparasiticide is an antiparasitic drug used in the treatment of ectoparasitic infestations. These drugs are used to kill the parasites that live on the body surface. Permethrin, sulfur, lindane, dicophane, benzyl benzoate, ivermectin and crotamiton are well known ectoparasiticides. Additionally, ectoparasiticides have been used to safely contaminate rhinoceros horns with hopes of it deterring the demand for these horns on the black market. Variants Permethrin Broad-spectrum and potent pyrethroid insecticide and is most convenient for both scabies and lice. First choice drug. Permethrin exerts its therapeutic effect by disrupting sodium transport across neuronal membranes in arthropods, inducing depolarization. This mechanism ultimately leads to respiratory paralysis in the affected arthropod, establishing permethrin as a potent agent in managing scabies and pediculosis.

Silicon Dioxide
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , commonly found in nature as quartz. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and abundant families of materials, existing as a compound of several minerals and as a synthetic product. Examples include fused quartz, fumed silica, opal, and aerogels. It is used in structural materials, microelectronics, and as components in the food and pharmaceutical industries. All forms are white or colorless, although impure samples can be colored. Silicon dioxide is a common fundamental constituent of glass. Structure In the majority of silicon dioxides, the silicon atom shows tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a li ...

Wattle (anatomy)
A wattle is a fleshy Caruncle (bird anatomy), caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, Snood (anatomy), snoods, and earlobes. Wattles are generally paired structures but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism. In some birds, caruncles are erectile tissue and may or may not have a feather covering. Wattles are often such a striking Morphology (biology), morphological characteristic of animals that they feature in their common name. For example, the southern and northern cassowaries are known as the double-wattled and single-wattled cassowary, respectively, and a breed of domestic pig is known as the red wattle hog, Red Wattle. Birds Function In birds, wattles are often an ornament for courting Sexual selection, potential mates. Large wattles are correlated with high testos ...
