Abstract
Aspidiotus destructor is a well-known pest of several tropical crops, mainly coconuts and bananas, and is present in most tropical countries. In Fiji it was a serious menace to the copra industry, and attempts to control it by biological means were made in 1920, when parasites were introduced from Tahiti ; in 1927, when other parasites were introduced from Java ; and in 1928, when predators were imported from Trinidad. The introductions made in 1920 and 1927 proved of no economic value, but the predators from Trinidad completely suppressed the pest in 1928 and 1929, and have controlled it most satisfactorily ever since.
