Abstract Biocontrol on Haiti is mainly in the form of classical biological control. Successful early projects are control of citrus blackfly by a hymenopteran parasitoid since the 1930s and control of the sugarcane borer by an introduced tachinid parasitoid since 1953. After 1970 three hymenopteran parasitoids were introduced for control of the coffee berry borer. A new project concerns the introduction of predators against the fluted scale Crypticerya genistae. Most Haitian farmers have insufficient financial resources to apply chemical control, which creates possibilities for use of conservation biocontrol and also allows the ecosystem service of biocontrol to exhibit its role in pest and disease reduction.
