Clidemia hirta (L.) David Don -- Melastomataceae
GO TO ALL: Bio-Control Cases
A shrub native to the West Indies and tropical South and Central America, Koster's curse became a serious introduced plant pest in Fiji. After a survey of insects attacking C hirta and related Melastomataceae, Liothrips urichi Karny (Thysanoptera: Thripiidae) was chosen as a promising natural enemy, and its life history and host plant relationships were intensively studied in Trinidad during 1927-1928 (Goeden & Andrés 1999). Potted C hirta infested with the thrips were shipped in cold storage to Fiji in 1930. On arrival the thrips were transferred directly to plants in the field. Field releases continued throughout 1930. By 1932-1933 several hundred hectares of thrip stunted C. hirta had been overgrown by plant competitors of greater forage value. Shaded and greatly weakened by thrips attack, these plants were soon defoliated and killed. Regrowth was readily located and attacked by the thrips. By 1937 the competitive ability f the weeds was permanently impaired by continued thrips attack except in a few shaded and wet areas, and successful biological control was attained (Simmonds 1937, Rao et al. 1971, Goeden 1978, Julien 1982).
