Tarsonemidae
Tarsonemidae is a family of mites, also called thread-footed mites or white mites. Only a limited number of tarsonemid genera (''Steneotarsonemus'', '' Polyphagotarsonemus'', '' Phytonemus'', '' Floridotarsonemus'' and ''Tarsonemus'') are known to feed on higher plants while most species in this family feed on the thin-walled mycelia of fungi or possibly algal bodies. Even among the plant-feeding tarsonemid mites, most are confined to areas of new growth where cell walls are thin and therefore easily pierced. However two species (the "broad mite" ''Polyphagotarsonemus latus'' and the "cyclamen mite" '' Steneotarsonemus pallidus'') are able to feed on older leaves because of their ability to inject toxins during feeding (presumably of salivary gland origin) causing an increase of thin walled cells surrounding feeding sites. This proliferation of new growth often results in leaves that appear stunted, puckered and twisted. Taxonomy Subdivision * Subfamily Pseudotarsonemoidinae ...

Tarsonemus
''Tarsonemus'' is a genus of trombidiform mites within the family Tarsonemidae. Description Adult ''Tarsonemus'' can be recognised by (among other features) simple unmodified setae on the dorsal idiosoma, two pairs of setae on the metapodosomal venter, short cheliceral stylets, and a gnathosomal capsule that is not conspicuously beaklike. Females of ''Tarsonemus'' have a pair of clubbed trichobothria on the prodorsum, ambulacrum I developed, the tegula short and rounded, the fourth leg pair clearly longer than the tegula, and the segugal apodeme developed. Ecology ''Tarsonemus'' mites live in various habitats including soil, litter, both woody and herbaceous plants, decaying wood, underneath bark (where they are associated with insects), animal nests, bracket fungi, stored foods, laboratory cultures and house dust. They are mostly fungivores and some are economically important pests of commercial mushroom cultures and laboratory fungal cultures. They can sometimes carry ...

Polyphagotarsonemus
The broad mite, ''Polyphagotarsonemus latus'' (Acari: Tarsonemidae), is a microscopic species of mite found on many species of plants, including important agricultural species such as grapes, apples, and other fruits. Broad mites are also currently affecting cannabis plants, as the industry matures with legalization. The mites are found in many areas throughout the world and are major pests in greenhouses. A ''P. latus'' infestation can cause stunting and twisting of the leaves and flowers, and blackening and death of new growth. The damage resembles that caused by herbicides. The mites prefer areas of high humidity and low temperature. They can be controlled by removing and destroying infested plants, and spraying with an acaricide Acaricides are pesticides that kill members of the arachnid subclass ''Acari'', which includes ticks and mites. Acaricides are used both in medicine and agriculture, although the desired selective toxicity differs between the two fields. Termino . ...

Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acarapis Woodi
''Acarapis woodi'' is an internal parasite affecting honey bees, the symptoms of infestation was originally observed on the Isle of Wight in 1904, but was not species description, described until 1921. ''Acarapis woodi'' mites live and reproduce in the invertebrate trachea, tracheae of the bees. The symptoms of ''Acarapis woodi'' infestation were originally called by beekeepers as the ''Isle of Wight Disease'', however it is now called List of diseases of the honey bee#Acarine (tracheal) mites, Acarine, after the Subclass to which the mites belong. All mites are arachnida, arachnids like spiders. The female mite attaches 5–7 eggs to the tracheal walls, where the larvae hatch and develop in 11–15 days to adult mites. The mites parasitize young bees up to two weeks old through the tracheal tube openings. There, they pierce the tracheal tube walls with their Arthropod mouthparts, mouthparts and feed on the hemolymph, haemolymph of the bees. More than a hundred mites can populate ...

Steneotarsonemus Pallidus
The cyclamen mite (''Phytonemus pallidus'') is a tiny mite often found as a pest on African violets and cyclamen ''Cyclamen'' ( or ) is a genus of 23 species of perennial flowering plants in the family Primulaceae. ''Cyclamen'' species are native to Europe and the Mediterranean Basin east to the Caucasus and Iran, with one species in Somalia. They gro ... plants. It is invisible to the naked eye, measuring only 0.02 cm (0.01 inch) at maturity. It requires a warm, humid environment, and is therefore problematic primarily in greenhouses. References Linquist, E.

Phytoseiidae
The Phytoseiidae are a family of mites which feed on thrips and other mite species. They are often used as a biological control agent for managing mite pests. Because of their usefulness as biological control agents, interest in Phytoseiidae has steadily increased over the past century. Public awareness of the biological control potential of invertebrates has been growing, though mainly in the US and Europe. In 1950, there were 34 known species. Today, there are 2,731 documented species organized in 90 genera and three subfamilies. Subfamilies The family Phytoseiidae contains these subfamilies: * Amblyseiinae Muma, 1961 * Phytoseiinae Berlese, 1916 * Typhlodrominae Scheuten, 1857 Anatomy and life cycle Phytoseiid eggs can be found along the vein of the bottom side of a leaf; They are oblong and translucent white. The larvae of these mites range from translucent white to tan in colour. They are tiny and oval in shape and size, have six legs, and are wingless. Nymphs look simil ...

Dicofol
Dicofol is an organochlorine pesticide that is chemically related to DDT. Dicofol is a miticide that is very effective against spider mite. One of the intermediates used in its production is DDT. This has caused criticism by many environmentalists; however, the World Health Organization classifies dicofol as a Level II, "moderately hazardous" pesticide. It is known to be harmful to aquatic animals, and can cause eggshell thinning in various species of birds. Difference between dicofol and DDT Dicofol is structurally similar to DDT. It differs from DDT by the replacement of the hydrogen (H) on C-1 by a hydroxyl (OH) functional group. One of the intermediates used in its production is DDT. Chemistry Dicofol is usually synthesized from technical DDT. During the synthesis, DDT is first chlorinated to an intermediate, Cl-DDT, followed by hydrolyzing to dicofol. After the synthesis reaction, DDT and Cl-DDT may remain in the dicofol product as impurities. * Formula: C14H9Cl5O * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metarhizium Anisopliae
''Metarhizium robertsii'' formerly known as ''M. anisopliae'', and even earlier as ''Entomophthora anisopliae'' (basionym) is a fungus that grows naturally in soils throughout the world and causes disease in various insects by acting as a parasitoid. Ilya I. Mechnikov named it after the insect species from which it was originally isolated – the beetle ''Anisoplia austriaca''. It is a mitosporic fungus with asexual reproduction, which was formerly classified in the form class Hyphomycetes of the phylum Deuteromycota (also often called Fungi Imperfecti). Many isolates have long been recognised to be specific, and they were assigned variety status, but they have now been assigned as new ''Metarhizium'' species, such as ''M. robertsii'', '' M. majus'' and '' M. acridum'' (which was ''M. anisopliae'' var. ''acridum'' and included the isolates used for locust control). ''Metarhizium taii'' was placed in ''M. anisopliae'' var. ''anisopliae'', but has now been described as a s ...
