A study of Diatraea saccharalis F. (Lepidoptera:Crambidae) and its effects upon sugarcane was made from 1958 through 1960 on St. Croix in the U.S. Virgin Islands. Diatraea is our principal sugarcane pest, its attacks on B.37161 cane ranging up to 43.94 percent of all joints bored during the study period. Parasitization of Diatraea eggs by Trichogramma minutum Riley (Hymenoptera:Trichogrammatidae) averaged over 97 percent. Pupae and larvae were not found to be parasitized, so Lixophaga diatraea Town-send (Diptera:Tachinidae) was imported and released at five locations on the Island. Nine months after release this tachinid fly was apparently established.
