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]
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]
At higher doses (100 μg/spider), the shape changed more, and the web design became irregular. All the drugs tested reduced web regularity except for small doses (0.1–0.3 μg) of LSD, which increased web regularity. [12] The drugs were administered by dissolving them in sugar water, and a

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.
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.
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 ...
