Conservation biological control, implemented in the 1910s by erecting perches in rice fields for insectivorous birds, resulted in effective control of the fall armyworm. Guyana is supposed to be the first country where the tachinid parasitoid Lydella minense, which had been collected in 1932 in Brazil, was successfully introduced for sugarcane borer control in the same year. During this period, several native natural enemies of this borer, as well as of other pests, were also identified as a result of prospecting projects. Guyana provided some of these species to other countries in the region. Classical biocontrol projects during the period 1970-2000 were attempted and the pink hibiscus mealybug was brought under complete control in 1998 by a parasitoid and a predator. Current projects concern classical biocontrol of the carambola fruit fly by parasitoids, augmentative control of the red palm mite by predatory mites, augmentative control of the palm castniid by a native entomopathogenic bacterium and conservation biocontrol of pests in rice.
