Abstract: Numerous introductions of natural enemies of insects, weeds and other organisms have taken place in the Caroline and Marshall islands, especially since 1945. Rodolia pumila and several other species of coccinellids have been widely distributed for control of Icerya spp. and Aspidiolus destructor. Many of these species successfully established on the high islands of Micronesia. On atolls, sketchy information suggests that R. pumila established, dramatically reduced populations of fluted scales, and then became extinct. Periodic reintroductions seem necessary to maintain these predators on atolls. Other successful introductions include a variety of predators and parasites for control of Oryctes rhinoceros including a virus, several parasitic Hymenoptera directed against Aleyrodidae, predatory snails for control of giant African snail, and a variety of insects for the control or lantana and clidemia. Though many of the biological control agents are known to have established, little information is available as to their impact on target pests.
