Scirtothrips dorsalis Hood 1919 - (yellow tea thrips)

This thrips is a polyphagous species found in Asia, Australia, Africa and the Americas. It has been suggested that the native range is southern Asia and the Australia-Pacific regions and that the species has been introduced into Africa and the Americas. In North America it was first recorded in 2005. Crops attacked are mainly vegetables, ornamentals and fruit crops. It is also a vector of tospoviruses.

Based of DNA analysis of seven nuclear markers, S. dorsalis has been regarded as a complex of several closely related (cryptic) species. Some of these species are particularly invasive. For example, the species temporarily named "South Asia 1" and "East Asia 1" have spread to North America (Kumar et al. 2017).
