The thrips species Liothrips urichi from Trinidad is being used to biologically control C. hirta; it was first employed on Fiji in 1930 (Simmonds, 1933).
The Clidemia thrips Liothrips urichi is used as a control agent to stop the spread of Clidemia hirta in Hawai'i.
Given S. dorsalis’ broad polyphagy and long history of pestilent behavior, it has been speculated that a weed such as castor that was adopted for agriculture may have been one of several hosts of origin, and that the thrips adapted and began to exploit other hosts as they became available in the changing agricultural landscape.
Some are minor but oddly consistent spelling errors (e.g. "N. bicalcurata," "U. reinformis," "U. humboltii," "thripes," and others).
