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.
The mites are found in many areas worldwide and are major greenhouse pests. P. latus infestation can typically cause stunting and twisting of the leaves and flowers, blackening, and death of new growth. The damage resembles that caused by auxin herbicides, which are thought to be a result of toxins produced in their salivary glands. [2]
Spider mites feed on hundreds of different plants, including vegetables, fruits, flowers, shrubs, trees, and houseplants. As the name indicates, they’re related to spiders and have eight legs ...
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 .
Mites of this family have the cheliceral bases fused into a structure called a stylophore, which can be moved independently of the subcapitulum and can be retracted into the prodorsum. The movable digits of the chelicerae resemble stylets , being greatly elongated, and their bases are strongly recurved within the stylophore.
However, their broad spectrum of activity varies for both spider mite control, and their ability to invoke resurgences of different spider mite species on various plants. Pesticides may be both lethal and repellent to Phytoseiids and other spider mite predators. After synthetic pyrethroids applications, spider mite development is shortened, the ...
