Thrips tabaci is a species of very small insect in the genus Thrips in the order Thysanoptera. It is commonly known as the onion thrips, the potato thrips, the tobacco thrips or the cotton seedling thrips. [1] It is an agricultural pest that can damage crops of onions and other plants, and it can additionally act as a vector for plant viruses.
The generic and English name thrips is a direct transliteration of the Ancient Greek word θρίψ, thrips, meaning "woodworm". [4] Like some other animal-names (such as sheep, deer, and moose) in English the word "thrips" expresses both the singular and plural, so there may be many thrips or a single thrips.

H. haemorrhoidalis are also susceptible to phosphine [13] [19] and have been controlled with 2 hours of fumigation with 620 ppm phosphine. [20] Other methods of microbial control have been used against the greenhouse thrips as well. Entomopathogens are a form of microbial insecticides that are used for thrips control. [15]
In order to protect their eggs, thrips insert their eggs into various types of plant tissue. Eggs can be found in the stems, leaves, or flowers of plants. [8] Thrips hatch in 2–3 days and complete their life cycle in 20–30 days. [2] Adult thrips feed on the flower bud, stem and leaf parts of the plant. [8]
Articles relating to the Thrips (order Thysanoptera), minute (mostly 1 mm (0.039 in) long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Different thrips species feed mostly on plants by puncturing and sucking up the contents, although a few are predators. Entomologists have described approximately 6,000 species.
The thrips vectors are not closely related, implying an independent origin of infection for each thrips, [3] possibly transmitted horizontally through shared hosts. There may be other species of thrips competent to transmit similar viruses, but they have not been documented on crops of economic significance.
