摘要：

Prickly pear cactus, introduced into eastern Australia by early settlers, became a major pest in the early twentieth century and caused abandonment of large tracts of rural land. Governmental strategies to halt the pest were ineffectual; some helped the cactus to spread. The discovery in the mid-1920s that the larvae of the Cactoblastis cactorum destroyed the pest was attributable more to luck than to cohesive policy.
