The western flower thrips [Frankliniella occidentalis (Pergande)] is an invasive pest insect in agriculture. This species of thrips is native to the Southwestern United States [1] but has spread to other continents, including Europe, Australia (where it was identified in May 1993 [1]), and South America via transport of infested plant material. [2]
Many flower-dwelling species bring benefits as pollinators, with some predatory thrips feeding on small insects or mites. In the right conditions, such as in greenhouses, invasive species can exponentially increase in population size and form large swarms because of a lack of natural predators coupled with their ability to reproduce asexually ...
Flower thrips can be agricultural pests in either two species of thrips in the genus Frankliniella: F. tritici , Eastern flower thrips F. occidentalis , Western flower thrips
Frankliniella is a genus of thrips belonging to the family Thripidae. [1] The genus was first described by Karny in 1910. [1] The genus has cosmopolitan distribution. [2] Frankliniella species can be quite variable in appearance, making identification challenging. [3] There are about 230 species in the genus. [3] Species include:
They are sites where a female has oviposited into developing flower buds or fruitlets. Despite the cosmetic damage suffered by these light skinned apple cultivars they are seemingly unaffected by most thrip vectored viruses. Infested apples of the mountain west simply provide a natural setting for Western Flower Thrips to thrive and reproduce.
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...

The chili thrips, Scirtothrips dorsalis, is an Asian pest on many crops, including chili peppers, roses, strawberry, tea, ground nuts, and castor bean. The western flower thrips, Frankliniella occidentalis , has recently expanded its range from western North America to large portions of Europe and Asia through the trade of greenhouse plants.
