Cordia curassavica: successful biological control of a noxious weed in Malaysia.
The selection and release of Metrogaleruca obscura and Eurytoma attiva for control of Cordia curassavica in coconut plantations in Malaysia in 1977 are described. The success of the program is emphasised. In a survey in 1992 in Sungei Yu, C. curassavica existed only in small scattered patches. Oecophylla sp., Crematogaster sp. and Cantheconidia [Cantheconidea] spp. preyed on M. obscura and Eupelmus spp. and Nanastatus spp. were parasitoids of E. attiva but these enemies did not prevent control of the weed. Chromolaena odorata and Passiflora foetida are mentioned as having replaced Cordia curassavica as major weeds of coconut plantations in Sungei Yu.
