Abstract

Aspidiotus destructor Signoret (coconut scale) occurs on bananas in Hawaii, infesting leaves and fruit. Seasonal population fluctuations on two banana varieties and a preliminary sampling plan for management decision making are described. There were distinct seasonal variations in A. destructor numbers on bananas in Hawaii and varietal differences in population densities and proportions of plants infested, with cv. Cavendish incurring highest A. destructor populations. An aggregated dispersion was found for A. destructor. A preliminary sequential sampling plan based on a nominal threshold is provided.
