Tetranychus urticae (common names include red spider mite and two-spotted spider mite) is a species of plant-feeding mite generally considered to be a pest. It is the most widely known member of the family Tetranychidae or spider mites. Its genome was fully sequenced in 2011, and was the first genome sequence from any chelicerate.
Tetranychus is a genus of spider mite. Tetranychus is one of the most economically important genera of mites, due to its high potential to destroy agriculture. [ 1 ] It contains 159 described species, the most significant of which is Tetranychus urticae .
Tetranychidae have eyes, 4 pairs of setae on the prodorsum, and a palptibial complex. Its two subfamilies differ in the structure of the empodium, which has tenent hairs in Bryobiinae and lacks them in Tetranychinae. [7] [8] Tuckerellidae have most dorsal setae expanded and leaf-like. The posterior margin of the body has a row of flagelliform ...
Spider mites are members of the family Tetranychidae, which includes about 1,200 species. [1] They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants , where they may spin protective silk webs , and can cause damage by puncturing the plant cells to feed. [ 2 ]
Tetranychus lintearius is a species of spider mite known as the gorse spider mite. It is used as an agent of biological pest control on common gorse, a noxious weed in some countries. The adult mite is half a millimeter long and bright red. It lives in colonies in a shelter of spun silk spanning many branch tips.
Panonychus ulmi, the European red mite, is a species of mite which is a major agricultural pest of fruit trees. [1] It has a high reproductive rate, a short generation time (21 days at 20 °C or 68 °F) and produces many broods in a year, all of which contribute to its pest status. [1]
Bryobia is a genus of mites in the spider mite family, Tetranychidae. The taxonomy of the genus is difficult. The genus has been revised several times. It is difficult to distinguish these tiny species from each other on the basis of morphological characters, and there is little agreement on which characteristics are of importance.
