Status of Ategumia matutinalis as a biocontrol agent for Clidemia hirta in Hawaii

Ategumia matutinalis, a pyralid leaf roller, was collected from the melastomes Heterotrichum cymosum in Puerto Rico and Clidemia hirta in Trinidad, West Indies. It was released in Hawaii in 1969 to control Clidemia hirta. Parasitism of the leaf roller's larvae by four species of hymenopterans may account for low field populations, suggesting that biotic interference limits the effectiveness of this biocontrol agent.

Review and status of biological control of clidemia in Hawaii
Efforts to control clidemia (Clidemia hirta) in Hawaii with phytophagous insects began in 1952. Several attempts have been made since then to introduce potential biological control agents to reduce the spread of this weed into forest areas, and other control measures have been tried by various groups and agencies. It was not until recently, however, through the enactment of significant legislation and subsequent funding, that explorations and studies were conducted specifically on clidemia insects in Trinidad, West Indies. Fourteen species of insects were evaluated. Studies indicated that several species were sufficiently host-specific to warrant introduction into Hawaii for the biological control of clidemia.
