The larvae rotate as they produce silk until the matting of threads forms a thin continuous scale around the periphery of the larvae. The scale covers the entire larvae. After accidental introduction to various Pacific islands, this scale became a serious pest of coconuts. Largely because of efficient parasitoids and predators this scale is generally not a problem in Hawaii. As in the use of all chemicals, consult the label or a pesticide database, to determine what chemicals may be used on specific crops.
Sprays are only effective on the crawler stage of scales.
However, control is difficult on other life stages. Chemical applications should be used only when parasites are not economically effective. The application of pesticides may kill natural enemies of the scale and result in a resurgence of the pest. Aspidiotus destructor Signoret, an Armored Scale Pest New to the Hawaiian Islands.
