Coconut scale Aspidiotus destructor (Hemiptera: Diaspididae) seasonal occurrence, dispersion and sampling on banana in Hawaii
International Journal of Tropical Insect Science 25 (2), 80-85
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.

A Hawaii, la cochenille du cocotier Aspidiotus destructor (Signoret) infeste les feuilles et fruits sur bananier. Cette publication décrit les variations saisonnières de ses populations sur deux variétés de bananier ainsi qu'une méthode d'échantillonnage destinée à mieux gérer les campagnes de lutte. Nous avons montré que le nombre d´A. destructor présent sur bananier varie avec la saison et la variété. Ainsi la densité de cochenilles et la proportion d'arbres infestés sont plus élevés sur la variété Cavendish. Nous avons trouvé que la distribution d´A. destructor est agrégative. Une méthode d'échantillonnage séquentielle basée sur un seuil minimum est proposée.
