The diet of the inhabitants of the island of Tristan da Cunha in the South Atlantic, consists principally of potatoes that are grown in walled ""patches"" which provided some shelter from the strong winds. An insect pest, locally known as the"" potato grub"" caused extensive damage to the potato crop. According to Naude (1947) the insect had been identified as Meliana exul. Very little was known about the pest. Members of the recent expedition to Tristan da Cunha did a study but had to limit their activities to testing three insecticides.
