ResumoThe movement of sterile adult tobacco budworms, Heliothis virescens (F.), and corn earworms, Heliothis zea (Boddie), from St. Croix to the islands of Vieques and St. Thomas was detected by operating traps baited with females on the other islands and by inspecting host plants for the presence of marked eggs. On Vieques, 18 of 260 tobacco budworms and 2 of 5 corn earworms captured were marked insects that had been released on St. Croix. On St. Thomas, 5 of 223 tobacco budworms captured were marked insects that had been released on St. Croix. On Vieques, 4 marked tobacco budworm eggs were found. The islands are therefore not completely isolated from each other from the standpoint of insect movement.
